Dusts last longer than aerosols, but the crack and crevice tips on the Phantom and Bedlam areosols enable you to get into the smallest cracks. It is a good idea to use a combination of sprays and dusts. Temprid SC may be used on the tufts and seams of mattresses. It works well as a residual insecticide sprayed in other recommended treatment areas such as night stands, chests, dressers, couches and chairs.
Bed bugs are obligatory bloodsucking. They have mouth parts that saw through the skin, and inject saliva with anticoagulants and painkillers. Sensitivity of humans varies from extreme allergic reaction to no reaction at all (about 20%). The bite usually produces a swelling with no red spot, but when many bugs feed on a small area, reddish spots may appear after the swelling subsides. Bedbugs prefer exposed skin, preferably the face, neck, and arms of a sleeping person.
