Pesky Pests 2: IPM – Monitoring your buildings and collections

In part 2 of our Pesky Pest blog, we will look at monitoring buildings and collections to ensure early detection of pest and fungal activity. It is recommended that a formal building and collection inspection program is developed and implemented to ensure consistency by all who carry out the inspections. Also ask for cleaning staff to report any evidence of pest or fungal activity before they remove the evidence to prevent activity going undetected.

Ensure the buildings housing collections are regularly inspected and any issues identified be addressed as soon as possible. If you have a facilities manager work in collaboration with them if possible. The inspection should cover external as well as internal areas. In addition to standard building maintenance issues, look out for existing or potential pest entry points and issues that will create a more inviting environment for our biological foes. This may include identifying areas that are cluttered with poor air movement, leaking pipes and vegetation growing up against buildings.  Are windows and doors regularly left opened? It is helpful to use a standard museum facility report to carry out your building inspection. If you would like a copy of a template, please contact your MDO.

In addition to inspecting items already in your collection, check all incoming objects and paper materials for evidence of prior or current pest and mould activity. Ideally this should be done in a dedicated quarantine area that is close to the entrance of the building and separate from the collection and display areas.

In addition to regular building inspections, it is essential to develop and implement a formal pest and fungal monitoring program for all collection storage and display areas. All staff and volunteers (including cleaning staff) who work near or with collections should receive regular training so they are familiar with all components of the monitoring program and can keep an eye out for early signs whilst going about their daily activities.

Ideally the collections should be checked once a week in the summer months and fortnightly in the cooler months. The regularity of the inspections will be guided by availability of staff or volunteers so make sure the schedule is practical.

The monitoring program should include regular visual inspections as well as the use of insect blunder traps. A bright torch should be used during inspections to see into dark spaces. A 10x magnifier with a built-in light is also invaluable to help identify little critters.

The monitoring program should include the following components:

Check:

  • Floors and walls
  • Window sills and the inside of ceiling light fixtures as many pests will fly or crawl to light.
  • Display cases and shelving.
  • Baseboards, under furniture, behind mouldings, in cracks in floors, behind water heaters and in air ducts.
  • On the outside and inside of storage enclosures as well as behind and under them.

Look for:

  • Live adults and larvae and the presence of shed larval skins or faeces.
  • Feeding debris or frass around or below specimens.
  • Exit or feeding holes
  • Hair falling from fur or pelts, mats of fibres, silken feeding tubes or cases, or moth or beetle pupae.
  • Insect eggs.
  • Fungal activity

Trap:

  • Place blunder traps throughout collection storage and display areas. Details on effective blunder trap monitoring will be covered in the next Pesky Pests blog.

Record:

  • Create an IPM Log and record pest and fungal activity. This will include number and type of pests and location of outbreaks. An IPM Log template is available on request from your MDO. Over time you may notice seasonal patterns and identify locations that are more conducive to biological activity. You can use this information to implement proactive measures such as extra monitoring, improving storage conditions or moving collections to a safer location.
  • It is important to accurately identify insect species. This will also be covered in the next installment of the Pesky Pests blog.

Take action if live pest or mould activity is discovered:

  • We will explore safe freezing and low oxygen methods in Pesky Pests 4. If you need assistance in the meantime, please consult your MDO or a conservator to determine which method is best suited to your situation.

Next time in Pesky Pests: We will delve further into the exciting world of blunder traps and insect identification.

Pesky Pests 1: What is IPM ?

Protecting collections from pest and fungal damage is one of the greatest challenges faced by cultural heritage custodians. The most effective approach to controlling pest and fungal activity in collections (including any personal collections) is a well-considered, practical Integrated Pest Management (IPM) program. So if you thought IPM was just used in the agricultural sector, think again. The aim of my new Pesky Pests series is to help you plan and effectively implement an IPM program for your collection and help you identify and eliminate your pesky biological foes.

A successful IPM program is all about proactive actions including good housekeeping practices, regular monitoring, effective building maintenance and the creation of a hostile environment for enemies. Regular applications of toxic pesticides and fungicides are not recommended and should not be necessary.

So what does a successful IPM program look like:

An organisation-wide acceptance of the principles of IPM and a willingness of all to learn and implement routine actions needed to protect the collections. These actions include:

  • Training of all staff and volunteers (including cleaning staff).
    • Contact your local MDO if you would like help with this.
    • Run regular refresher IPM sessions on an annual basis.
  • Prevention of entry of pests, such as insects, birds, and rodents, into buildings
    • Moderate the interior climate and avoid high relative humidity and temperatures.
    • Develop good exterior building maintenance and appropriate landscaping.
    • Inspect all incoming objects and paper materials for evidence of prior or current pest and mould activity, and inspect stored collections periodically for insect and mould activity. This includes materials such as stationary supplies.
  • Avoidance of practices and habits that attract pests and fungal activity:
    • Moderate the interior climate and avoid high relative humidity and temperatures.
    • Develop and maintain good interior housekeeping practices.
    • Maintain appropriate food restrictions and food/rubbish removal practices.
  • Implement measures to detect pests and fungal activity:
    • Set up and maintain a pest and fungal monitoring program for all collection storage and display areas. This should include regular visual inspections as well as the use of insect blunder traps.

Next time in Pesky Pests: We will look at how to check your buildings and collections for potential and existing risk factors and discuss mitigation strategies.

 

 

The conservation of a fire damaged print

IMG_6907

Fire damaged print of ‘Menin Gate before midnight’ before conservation treatment.

This blog will outline the conservation treatment I carried out on a print that was damaged in the fire last June at the Waltzing Matilda Centre in Winton. The print was on loan to the Winton and District Historical Society for their ANZAC exhibition “More than a name” when the fire struck. The print suffered water damage, weakening of the paper support and isolated areas of charring.

The print is a duplicate of the iconic oil painting “Menin Gate at Midnight” painted in 1927 by Australian artist William Longstaff. The painting depicts the shadowy ghosts of fallen soldiers marching past the Menin Gate Memorial in Belgium. The image gained iconic status in Australia as the nation mourned the thousands lost in World War One.

The treatment process took approximately 4 days to complete and involved the following steps:

Step 1: Surface cleaned front of the print

Charred areas of print surface before treatment.

  • The surface of the print was cleaned using a soft brush and air compression avoiding the charred areas.

Step 2: Consolidating the charred areas – part 1:

  • The weak charred areas on the front of the print (see right) were consolidated with a thin Japanese Tissue (Bib Tengujo) and wheat starch paste to prevent any loss of the damaged paper. The tissue was then carefully toned using pastel pencils to reduce the visible impact of the charred areas.

Step 3: Removal of the window mats:

Water damaged window mat and strawboard backing board.

  • The window mat was mechanically removed.
  • Under the  mat board was a thick layer of adhesive tape residue which had to be removed from the surface of the print (see image below right). As the paper support was very porous, it was necessary to use methyl cellulose poultices to soften the adhesive as direct applications of water would have caused staining of the paper.

Step 4: Backing board removal:

  • Once the window mat was removed the acidic and charred backing boards, which the print had been directly adhered to, were removed.

  • The first layer of mat board was very thick strawboard which had swollen significantly on exposure to water (see image above right). Most mat boards are a composite of a number of layers of paper glued together which can be carefully removed layer by layer. Straw board is made by compressing straw pulp in one thick layer. If the board gets wet, the pulp forms dense clumps of fibres which make removal very difficult and time consuming. The removal of the board had to be carried out without water and took more than two days.
  • Under the strawboard was another thinner mat board layer that was also removed. The bulk of the mat board layers were removed dry. Fortunately the second backing board was layered in structure making removal much easier than the strawboard layer.

Step 5: Consolidation of charred areas – part 2:

  • The charred areas of the print were consolidated on the back of the print using Lens Tissue and wheat starch paste.
  •  Areas where the paper was weak but not charred were also consolidated.

Step 6: Reduction of water staining:

  • The water solubility of the printing inks was tested and found to be stable so the print was blotter washed in deionised water to reduce the heavy staining. Blotter washing uses capillary action to gently remove any soluble staining and discolouration without the need to apply water directly to the paper surface. The treatment was successful and reduced the staining making it much less visibly intrusive to the image.

Step 7: Cleaning the brass plaque:

  • The brass plaque was cleaned by firstly brushing off any loose dirt and then very gently cleaned with a jewellers’cleaning cloth. This did not change the appearance of the plaque but further treatment was not carried out to prevent damaging the surface.

Step 6: Rematting and reframing:

  • A new window mat package was created matching the original mat configuration including the brass plaque. Canson 100% cotton cellulose mat board was used for the mat and backing board.
  • The print was then placed in its original cleaned frame. New glazing and an archival quality backing board were used to seal the frame package.

Early on Wednesday 1st December, a fire broke out at the Hervey Bay Historical Village and Museum.  The fire started in the rear building adjacent to the Workshop. The fire has caused major damage to a number of historic vehicles, stationary engines and machinery. The Museum’s tools were also destroyed in the blaze.

Thankfully the fire was contained to the Workshop area and the rest of the village was left unscathed and the Museum will be open as normal.

Since the fire, the Museum has been overwhelmed by offers of help and donations of tools. They are confident that the future is bright and the fire has made them more determined than ever to keep improving the Museum for their visitors.

For more information and to see images of the damage, please go to the Museum’s website: http://herveybaymuseum.com.au/stop-press/

2015 Cultural Heritage Network- Toowoomba Region Seminar – Preserving our Heritage: Metals, Textiles, Photographs

On the 24 and 25 October, the Cultural Heritage Network – Toowoomba Region (CHN-TR) held their annual seminar at the Pittsworth Function Centre. The seminar was supported by a successful application by the CHN-TR to the Regional Arts Development Fund.  The Regional Arts Development Fund is a Queensland Government initiative through an Arts Queensland and Toowoomba Regional Council partnership to support local arts and culture.

Over 25 people attended the seminar with participants coming from not only the Toowoomba region but as far afield as Brisbane, Canungra and even the UK. The seminar began with a thought provoking opening address by Councillor Ros Scotney (Toowoomba Regional Council). Then three workshops on the care of metals, textile and photographic collections were run simultaneously. Topics covered over the two days included object identification, safe cleaning and handling methods, and suitable display and storage techniques and materials.

Dr. Michael Marendy (Textile Conservator) was the textile workshop instructor, I ran the photographic session and Christine Ianna (Heritage collections and conservation consultant) presented the metals workshop.

After the workshops, participants were given a tour of the Pittsworth Pioneer Historical Village.

I would like to thank the CHN-TR particularly Karen Barrett and Rhonda Brosnan for all their hard work. I would also like to thank Belinda McKinlay, Pittsworth Function Centre Manager for running around after us and lending me her microplane grater so that the participants of my workshop could surface clean the backs of their photos. Finally a big thank you to the participants of the photo workshop for their good humour and enthusiasm.

The curse of the clothes moth

The curse of the clothes moth!

A recent job has reminded me of how devastating clothes moth infestations can be in textile collections. There are two types of moth species that cause damage, the casemaking clothes moth (Tinea pellionella) and the webbing clothes moth (Tineola bisselliella). More information on each clothes moth species can be found at: https://www.aepma.com.au/PestDetail/98/Clothes%20Moth

Carpet beetles can also cause major textile damage.

Serious infestations can develop undetected in collection storage and display areas causing significant damage particularly to animal fibres such as wool, silk and fur. Moths prefer dirty fabric when laying their eggs and are attracted to textiles containing human sweat or other liquids that have been spilled onto them. It is the fabric-eating larvae that causes damage not the adult moths.

If you find infested objects, it is important to deal with the problem as quickly as possible.

If the objects have been badly damaged, are very fragile, or have significant heritage value, it is strongly recommended that you seek advice from a qualified textile conservator before undertaking any treatment.

If the textiles do not contain wood or glass components, they may be suitable to freeze. When packing collections for freezing, make sure objects that are badly damaged and/or fragile are properly supported during the packing process. See the State Library of Queensland info guide on safe freezing methods: http://www.slq.qld.gov.au/resources/preserving-collections/preservation_guides/freezing-water-damaged-and-insect-infected-collections

Once the objects have been frozen and safely defrosted, careful brush vacuuming can effectively remove larvae as well as surface dirt, hair and lint which could sustain future infestations. Be sure to also thoroughly vacuum storage and/or display areas including edges of carpets, along baseboards, underneath furniture, inside closets and other undisturbed areas where clothes moth larvae feed. Refer to the following websites for instructions on how to safely vacuum textiles: http://www.museumtextiles.com/uploads/7/8/9/0/7890082/vacuuming_textiles.pdf

http://www.powerhousemuseum.com/pdf/preservation/how_to_brush_vacuum_an_object.pdf

Remember that freezing will not prevent future infestations.

You can minimise the risk of infestations by implementing a collection-wide Integrated Pest Management (IPM) plan:

Tips on salvaging fire damaged collections

Given the recent fire at the Waltzing Matilda Centre in Winton, it is timely to share a few tips and useful websites on salvaging fire damaged objects.

Below I have outlined the basic salvage procedure. For more information please refer to the provided websites or contact your local MDO or a qualified conservator for specific advice.

Gentle reminder: Make sure your disaster preparedness plan is up to date and those involved in the disaster team are familiar with its contents and have received recent hands on salvage training.

“Play the ball” at the Ration Shed Museum

MDO Lydia Egunnike began her NAIDOC week by attending the launch of a new exhibition celebrating the extraordinary sporting history of Cherbourg, a small town in the South Burnett region. Cherbourg, or Barambah as it was originally called, was established by Salvation Army member William Thompson in 1899. It became a Government Settlement in 1904. Under the “Aboriginal Protection Act” Aboriginal people from across Queensland and New South Wales were relocated to Cherbourg. From its beginnings, the community produced an exceptional number of local, state and national champions across a wide range of sports. Many of the surrounding communities recruited team members from Cherbourg. The Ration Shed museum celebrates this history in their new exhibition “Play the ball”.

The day began at the Cherbourg cemetery with the poignant unveiling of a new headstone for Frank “Big Shot” Fisher, a Cherbourg legend, and rugby league great.

After a hearty morning tea, the “Play the ball” exhibition was launched with the cutting of the ribbon by former local ruby league player Uncle Cecil Brown. Chris Sarra (on behalf of the Australian Rugby League Commission) presented a presentation plaque celebrating the Cherbourg rugby league “Team of the Century”.

“Play the ball” shares the triumphant and moving stories of Cherbourg’s sporting champions and unsung heroes. The exhibition uses a vibrant mix of photographic, oral history and audio-visual content. A number of original objects such as trophies are also on display.

The audience is encouraged to reflect upon the social, political, and cultural context in which these sporting achievements occurred. They are also reminded of the potential power of sports to instil pride and bring communities together. The exhibition has been developed as “a reconciliation process for Cherbourg and surrounding communities, a display of local pride in achievement, an affirmation of prowess and ability, and a demonstration of what is possible to the community youth.” (http://rationshed.com.au/play-the-ball-the-story-of-sport-in-cherbourg/).

Gayndah Flood Recovery Phase Two

In February 2013 communities in the Bundaberg, Burnett and Frazer Coast region were inundated by flood waters in the wake of ex tropical cyclone Oswald. In an initial disaster response, Queensland Museum’s MDO team worked with museums at Gayndah, Bundaberg and Maryborough to salvage collection material, and provided assistance to museums faced with the massive clean up task.

Eight months later, five MDOs, and Queensland Museum’s Director of Regional Services, Deborah Bailey, returned to Gayndah to help volunteers deal with the next phase of disaster recovery. The three day trip was also a chance for the MDOs and volunteers to get some invaluable applied onsite training.

Earlier posts on the blog outline the process for freezing paper-based materials.  Frozen material can be dealt with later, at a more convenient time for people whose lives have been disrupted by a disaster.

To prepare for the unfreezing process, Gayndah and District Historical Society volunteers removed the wrapped packages from the freezer two days before the MDOs arrived. They wrapped them in towels and placed them in an undercover, shaded area to slowly defrost.

Lydia Egunnike, MDO for the southern inland region, organised all materials needed for the workshop, including vast quantities of paper towels, plastic spatulas and clean water. John Wein, the Secretary of the Historical Society, ensured there were plenty of fly screens on hand that could be used for drying racks, bricks to make tables higher and prevent sore backs, and food for a hungry work crew!

Activities on the first morning involved setting up works stations and drying stations both inside and on the museum verandah.

Lydia then provided preliminary training on how to carefully separate documents, what to do if they were stuck together, how to clean away residual dirt and mud, and how to start drying them properly.

Each MDO and the six volunteers (John Wein, Mary McIntyre, Brian and Sue Hutchinson, Jamie Wilson and Judith Woodman-Heuth) then set about working through the bundle of frozen documents. With John providing advice about which documents or materials they could discard, much time was saved. John also started the process of scanning dried documents that contained important information but which were not going to be kept due to damage, mould and/or general condition.

Drying booklets, folders and archives was a primary goal. Items were interleaved with paper toweling, often two or three times over the course of the site visit. Some material was stuck together so tightly it needed to be re-submerged in clean water or re-wet and gently prised apart using finer, more professional conservation tools.

At the end of the three days, all frozen items had been assessed with the drying process underway. This was possible because of the large number of volunteers and MDOs available, but also due to the organisation and planning that had gone into preparing for the activity.

Many thanks again to the Historical Society at Gayndah volunteers for making the MDO team feel welcome and keeping us well fed.
