FAQs About Stored Product Pests
Does every small beetle indoors come from food?
No. Identify the insect and check whether it is associated with a stored product.
What should I do with infested food?
Discard it and inspect other susceptible products. Clean cabinet crevices and keep replacement food in well-sealed containers.
Will spraying the pantry solve it?
Insecticides do not reach pests inside food packages. Finding and removing infested products is essential; do not apply household sprays to stored food.
When should I request an inspection?
Contact us if identification is uncertain or activity continues after cleanup.

Jacob did a nice job of taking care of the squirrel nest. No chemicals were needed. Personable young man who was clear about what was needed and helped to remedie the problem.

The staff is very responsive to messages. Even though we had to be rescheduled a couple times due to rain, they didn’t just drop us. They took care of us when the weather cooperated. Very good to work with! Price is very reasonable too.
