Pest Control FAQs, answered by experts

Skunks are nocturnal creatures, meaning they are primarily active at night, particularly around dusk and dawn. Their activity levels increase as the weather warms up, and they are generally dormant or inactive during the winter. Skunks are especially active during the spring months when they are foraging for fresh food and seeking mates. While they are typically not seen during the day, daytime activity is possible if a skunk is having trouble finding food, has babies to care for, or is severely ill.

Any tree that emits a sap or resin can attract yellow jackets. They are particularly attracted to the tree of heaven (Ailanthus altissima), which emits a sweet sap that both yellow jackets and spotted lanternflies love.

Professional services cost between $75 and $150, depending on the size of the home and the severity of the infestation. Multiple treatments often increase costs.

There are quite a few opinions regarding using coffee grinds to keep deer out of your garden, with many people convinced of this method. It makes sense that it could work considering deer have a strong sense of smell and likely do not like the smell of coffee grounds. However, there’s no hard evidence supporting the notion that coffee grounds keep deer away, but it may be worth trying.

Stink bugs can start reproducing a couple of weeks after they leave the nymph stages, which gives them several months to mate and start laying eggs. A single stink bug can lay up to 400 eggs in a lifetime, which can worsen an infestation. Stink bugs lay significantly more eggs in warmer climates where they stay active longer and have several rounds of egg laying.
