A Point on Pest Control

Many thanks for publishing Mary Fisher’s fine article about my book, “Bugbusters: Getting Rid of Household Pests Without Dangerous Chemicals,” on Oct. 4. It was a significant contribution to home safety.

May I clarify one point? I would be very careful when putting boric acid in a cupboard. It should never be in contact with food or dishes and utensils. The safest way is to drill holes about six or eight inches apart in the kick plate of your kitchen or bathroom cabinets and blow the powder into that dead space. Then plug the holes with an appropriate patching compound. Roaches hiding there will be wiped out and there’s no danger to people and pets from the boric acid.
