Buying Guide
Bug sprays can be designed to keep bugs away (repellents) or to kill them. However, some sprays can do both. The types of repellents used on humans and pets are different from ones made to keep insects away from homes and outdoor spaces, though.
Bug killing sprays are considered to be insecticides. These products kill insects on contact, in most cases. While some are used for spot treatments and last for one application, others can create barriers or perimeters that last for weeks or months.
Bug killing sprays are generally made from chemicals called pyrethroids; these man-made pesticides are also found in other commercial products like pet sprays and pet shampoos. Common pyrethroids found in bug killing sprays include sumithrin, resmethrin and permethrin.
These chemicals are used in very low levels, but anyone who is accidentally exposed to an extremely large amount could have symptoms like nausea, headache, diarrhea and dizziness. Always follow the label directions when using these sprays.
Indoor spot treatment bug killer sprays work well on roaches, flies, ants, bedbugs and fleas, but if you want to keep them from coming back, look for products that have barrier protection.
There are also indoor foggers; these create fine mists that let the insecticide penetrate under baseboards and into crevices to kill insects that are not easily visible. Many of these sprays come in gallon-sized containers with attached spray wands. Note that you can use exterior foggers outside your house, but do not use these indoors.
