Pest Control questions, answered by experts

The best termite treatment depends on your specific infestation, home, and budget. According to the Environmental Protection Agency (EPA), the most common professional treatments are soil-applied barrier treatments, like liquid termiticides, and termite baits. Bait stations are placed in the soil and work by moving poison back into the colony to kill the queen. For infestations that haven't fully taken root, barriers and targeted termiticides are often the most effective options. Additionally, preventative measures such as moisture removal and installing physical barriers to protect vulnerable wood are important, particularly during construction or remodeling. It is best to work with a termite professional to determine the right treatment for your situation.

Bed bugs are most active when we are most inactive, typically from 2 a.m. until 5 a.m. They are cunning, and adjust their schedules according to their victims. If you work at night, for instance, your bed bugs will flip the script.

Naturally occurring EPA-registered Bti products are an effective way to kill off mosquitoes at the larval stage. And, although they won’t wipe them out, there are lots of natural repellents that make your yard less attractive to mosquitoes. Try planting some marigolds, lemon thyme, or other plants they’ll steer clear of, light a citronella candle or two, or lay some bug-offensive cedar mulch.

Look for goose repellents that contain the ingredient methyl anthranilate. This is a natural chemical found in grape juice. In human food, it’s often used as grape flavoring. With geese, it’s highly irritating. Grape Kool-Aid contains methyl anthranilate, the active ingredient in most bird repellents. It won’t harm geese, but it will deter them.

The best deterrents for possums include securing trash cans with tight-fitting lids, removing outdoor food sources like pet food or fallen fruit, and trimming tree branches that provide access to your roof or an open window. Motion-activated lights or sprinklers can also startle and discourage them from visiting. Additionally, you can take advantage of their strong sense of smell by using garlic, onion, or commercial possum repellents to keep them off your property.
