Silverfish can be found in wood piles, debris piled on the soil, in and under plywood and cardboard. They can easily climb up and find entrances into building. They often enter buildings from cardboard boxes, books and papers. Heat ducts from basements ca be ways to spread.
CONTROL OF SILVERFISH
Inspect their preferred habitat and eliminate moisture. Remove their food sources. Remove anything stored against or near the exterior. The cleared building can then be treated.
