Pest control materials, if left to volatilize or float in the air, can be as bad or even worse than the pests. But again it is a challenge, and we need to deal with it case by case, by conducting pros and cons analysis.
Below are some hints:
· Focus on preventing pests from getting into clean rooms in the first place.
· Take appropriate supplemental non-chemical steps to eliminate the source or the pest’s route of access to the building and the clean room.
· PMPs must act as consultants for their clients, advising them on sanitation, design, construction, and maintenance improvements that can be made in the building’s surroundings, on the building itself, and inside the building to make the whole area as unfriendly to pests and as impervious to pest invasion as possible.
· The central principle of clean-room Integrated Pest Management is to start from the facility’s outer surroundings; identify pest-conducive conditions and pest populations that are present; and then, working from outside in — from least-sensitive to most-sensitive — block and thwart a pest’s progress into the clean room.
· When it is necessary to apply a pest control device or, in rare cases, a pesticide, inside the clean-room environment, it must be done using materials and methods that reliably preclude the possibility that any contaminants will be added to the particulate load of the air in the clean room.
