Keep fireplace flues shut. Make sure that dog and cat entrances are insect proof. Since lights attract the insects at night, move them away from doors and windows. Remove ground squirrel, wood rat, and other rodent nests within 300 feet of the house. Eliminate harborages such as piles of lumber, firewood, and debris.
Check beds at night and shake out the bedding before getting into bed.
Keep beds at least 1 foot from walls and place doubled-sided sticky tape on the legs. In extreme cases a tent of mosquito netting over the bed that is tucked in all around the mattress will provide protection from the bugs. Residential, Industrial, and Institutional Pest Control.
