Pest Control FAQs, answered by experts

Fogging keeps mosquitos away for an average of 72 hours. This is the length of time that a mosquito fogging machine will continue to operate at peak performance for pest control and protection. After the initial 72 hours, the fogger may still keep mosquitos away but will gradually decrease in effectiveness.

Spotting a single scorpion in the home doesn’t mean you have a full-blown infestation, but it does mean there’s a way for them to get inside. Other scorpions could easily use the same method, like entering through an air vent, as these arachnids are social creatures that tend to live in groups. If you see a baby scorpion, however, that likely indicates a nest somewhere in the home. This is also true if you spot a scorpion with an infant on its back.

Scented mouse deterrents, like peppermint oil, can be effective in the short term. The pungent smells may temporarily repel mice, but they lose effectiveness as the scent fades or mice get used to it. The main drawbacks are frequent reapplication and the fact that these deterrents don't address the root cause of the infestation, such as entry points or food sources. While they can be part of a broader strategy, scented deterrents alone are rarely enough to eliminate a mouse problem.

No, pest-repellent plants can only reduce the number of pests in your garden—they won’t repel all of them. So, for example, a plant like catnip that repels mosquitoes won’t completely eradicate them from your yard.

Set live traps or install a one-way door to evict squirrels, rodents, and other animals from your attic. Once they’re out, seal any entry points to prevent the animals from returning. If you’re dealing with an infestation, call a pro.
