Treating insect and pest infestations
Generally, in Oxford, library material which may be affected
by woodworm will be treated by freezing.
Areas proven to have a silverfish infestation might have to be treated by the City Council with a residual pyrethroid-based wettable powder.
More often than not rodents will disappear if any source
of food is eliminated. Pest control contractors should only
be used as a last resort.

other creatures should NEVER be used for rodent control
If above normal insect activity is suspected in an area start by making a plan of the room. Acquire small sticky traps from Conservation and Collection Care Service and place them in strategic positions, such as under radiators, window sills, near skirting boards, under bookcases, etc. Remember to clearly label the traps with a date, number and location and to record this information on the plan. These traps should be checked once a day to begin with and then once a week. All insects should be identified and recorded, and the traps replaced as necessary.
Pheromone traps are one of the most valuable new tools for pest management. Pheromones are the natural scents insects use to communicate with each other. Certain pests can be strongly attracted to the traps from the surrounding area, providing an extremely effective early warning system of pest presence.
Insect electrocutors are useful for detecting and controlling flying insects. They emit ultraviolet light (black light) that attracts flying insects, particularly beetles, flies and moths. The insects are drawn into the trap and electrocuted or fall onto a glue board. These traps must be checked and emptied periodically or the dead insects will themselves attract dermestid beetles and other scavengers.

Potential pest infestations
By rapidly lowering the temperature to at least 35 °C and holding it at this level for up to several days, most life stages of most insects can be killed. While some commercial freezers are adequate for pest control, others are not able to lower the temperature quickly enough. A slow reduction in the temperature allows some insects to go into a state resembling suspended animation and survive the treatment. Naturally, it is important to ensure that the objects are not damaged by the low temperatures and that condensation is controlled.
Preparing material for freezing
If you think you might have items which show signs of active insect damage then Conservation and Collection Care Service are now able to offer
our freezer to control pests in infested objects. Material needs to be carefully prepared before freezing.
