Safety Tips for Spraying Insect Surfaces Effective insect surface sprays can last from 4 weeks to 3 months. You'll need to know how often you need to spray again to maintain protection. A typical pest control application will last around 90 days. If outdoor applications experience constant or heavy rainfall, their effectiveness may be affected and will last about 60 days.
Pesticides used to treat flying insects, such as mosquitoes or flies, last about 30 days. For a general application of preventive pesticides, it's best to do what professionals do and apply it every 90 days for continuous monitoring. As a general rule, light cleanings are perfectly fine three to five days after a treatment. Suspend the most vigorous cleaning until approximately two weeks have passed.
If you leave the spray and let it dry, it will continue to kill cockroaches with residual action for up to 2 weeks as long as insects come into contact with it. After spraying Raid in the general direction of the insects you want to get rid of, you may see some residue on the nearest surface. On the contrary, leaving the residue can keep the product active for up to two weeks, killing insects that come in contact with it. One of the most important things you can do after a pest control treatment is to eliminate easy entrances that insects, mice, and other irritants use to access your property.
Many seem to share the same concern, worrying about the potential health effects of pest control aerosols and what they should or should not do after a visit from a Smithereen technician. After the allotted two weeks have elapsed (see the “Waiting to Clean After Pest Control Spray” section), feel free to clean your cabinets, sofas, sofas and armchairs as you always would. In contrast, all insecticide sprayed onto “non-porous” materials, such as sealed tiles, is available for contact with the insect.
