Museums, archives and historic buildings

In a collection, the objects are the food source: wool, silk, feathers, fur, hide, horsehair, herbarium sheets, seeds, paper, glue and bindings are what the pests that matter in museums eat. A pest program built for an office building protects the building and misses the collection.

What this page establishes

  • The pests that matter in a collection are the ones that eat the collection, and each material has its own.
  • A blunder trap is a monitoring instrument only when its catch is identified to species, trended, and held against a threshold.
  • Repositories curating federally owned or administered archeological collections are held to a written standard that names insects and rodents.
  • Under NAGPRA, a past pesticide treatment becomes part of the itemized list, where known.

The collection is the food source

A general commercial pest program is organized around the pests that bother people: cockroaches, ants, mice, flies. Those matter in a museum too, but they are not the ones that destroy collections. The insects that do are specialists in dry animal and plant protein, cellulose, and starch, which is to say they are specialists in the materials museums keep. The useful way to organize a collections program is by material, not by room.

Collection materials and the pests that damage them
MaterialPests that damage it
Wool, silk, fur, feathers, hair, hide, and taxidermyDermestid beetles, including Anthrenus, Attagenus, and Dermestes; the webbing clothes moth, Tineola bisselliella, and the casemaking clothes moth, Tinea pellionella
Herbarium sheets, seeds, botanical and dried organic samplesThe drugstore beetle, Stegobium paniceum, and the cigarette beetle, Lasioderma serricorne
Paper, photographs, and bindingsSilverfish, firebrats, and booklice (Liposcelis)
Wooden objects, furniture, and historic structural woodAnobiid and powderpost beetles; termites
EverythingRodents, through nesting and gnawing

Read down the right-hand column and very little of it appears on a route technician's target list. A service visit that inspects the loading dock and the staff kitchen, replaces rodent bait, and treats a perimeter can be performed flawlessly and still never look at a textile store, a herbarium cabinet, or a drawer of study skins.

A trap catch is data only if someone can read it

Most institutions already run blunder traps. The traps are not the gap. The gap is what happens to them afterwards. A trap is a monitoring instrument only when three things are true of its catch: it is identified to species, it is trended against earlier catches from the same position, and it is held against a threshold that triggers a defined response.

A route service log typically records counts, or simply "activity." A count without a species cannot tell a casual intruder from a breeding population inside a case.

Species and context change the meaning of the same insect. A varied carpet beetle on a windowsill in May may well have come in from flowering plants outside. One in a textile store in January is more likely to have developed indoors, on something in the room. The trap log that records both as "one beetle" has recorded nothing a collections manager can act on.

Federal repositories carry a written standard

Repositories curating federally owned or administered archeological collections operate under 36 CFR Part 79. Its standards for determining whether a repository can provide adequate long-term curatorial services require that the collection be handled, stored, cleaned, conserved, and exhibited in a manner that protects it from breakage and possible deterioration from a list of agents that includes "insects, rodents and general neglect."

Two things follow. Pest protection is part of the standard the repository is measured against, not a building-maintenance line item. And the standard names general neglect in the same breath, and a monitoring program that is set up and then never read is hard to tell apart from it.

Every treatment becomes part of the object's record

Under the regulations implementing the Native American Graves Protection and Repatriation Act, the itemized list a museum or federal agency compiles for human remains and associated funerary objects includes "the presence of any potentially hazardous substances used to treat any of the human remains or associated funerary objects, if known."

A treatment applied to a collection does not stay in the service log. It travels with the object into consultation and repatriation. A documented, non-chemical program of monitoring, isolation, freezing, and anoxia keeps that record clean going forward, and a written history of past treatments, assembled from whatever records survive, is part of good stewardship of the collections that already carry one.

The building is part of the collection

In a historic house museum, a courthouse, a capitol, or a railroad depot, the structure is itself the artifact. Original framing, floors, and millwork are collection material in every sense that matters, and they are subject to termites and powderpost beetles like any other wood.

Assessment of that wood belongs in the same program as the collection monitoring, as does bird, bat, and rodent exclusion designed so that it does not damage historic materials. An exclusion job specified for a modern commercial building can do more harm to a historic fabric than the animals it keeps out.

How the work gets done

The practice writes the program, reads the traps, reviews the service records against the program, and trains the staff who carry it day to day. The recommendations are written to stand on their own, so any licensed pest management provider can carry them out, including one the institution already uses.

The citations this page rests on

Every entry states how far it has been verified: whether the primary source was read into this repository and on what date, or whether it is corroborated from secondary sources with the primary text still unread.

  1. 36 CFR §79.9(b)(5)(ii)

    36 CFR Part 79, Subpart B, §79.9(b)(5)(ii) — Curation of Federally Owned and Administered Archeological Collections: Standards to determine when a repository possesses the capability to provide adequate long-term curatorial services

    What it requires

    A repository curating a federally owned or administered archeological collection must handle, store, clean, conserve and exhibit it in a manner that protects it from breakage and possible deterioration from a named list of agents, among them “insects, rodents and general neglect.” Pest protection is written into the standard a repository is measured against, not left to the building’s maintenance contract.

    43 CFR Part 10, Subpart C, §10.10(a)(6) — Native American Graves Protection and Repatriation Regulations: Repatriation of human remains or associated funerary objects (itemized list)

    What it requires

    The itemized list a museum or federal agency compiles for human remains and associated funerary objects in its holdings must include “the presence of any potentially hazardous substances used to treat any of the human remains or associated funerary objects, if known.” A past pesticide treatment is part of the object’s record and follows it into repatriation.

Working with the practice in this sector

  1. A trap read

    Send your blunder traps, or photographs of them, and receive species-level identification and a one-page interpretation of what the catch means. Offered at no charge as a first engagement.

  2. Collections pest risk assessment

    Materials, storage, building, and current practice assessed together, delivered as a written report suitable for a grant application or an accreditation file.

  3. IPM program design

    Trap placement, identification protocol, thresholds, quarantine and incoming-object procedures, and non-chemical response, written for your collection and your staff.

  4. Vendor service-record review

    Whoever services the building, measured against the program: what their records show, what they miss, and what the contract should ask for instead.

  5. Staff training

    Recognition of the pests on your materials list, trap reading, and when a finding needs an entomologist rather than a vacuum.

For collections managers, registrars, and conservators

Do you know what your blunder traps caught last quarter?

Not how many. What. Send the traps, or photographs of them, with where and when each one was placed.

A count without a species is a number. A species without a location and a date is a curiosity.
