Pest Control FAQs, answered by experts

DIY treatments exist, but professional extermination is recommended for thorough elimination and prevention.

Getting roaches to completely go away will take a lot of effort, and they hardly ever go away on their own. You will likely need a combination of home treatments, like roach sprays and traps, and regular visits from an exterminator, to control an infestation. It can take awhile for these treatments to start working, and you’ll need to stay on top of replacing old traps and having additional extermination services, plus keeping your home clean and decluttered, to deter roaches.

Several bugs can look like ticks but aren’t, including beetles, bed bugs, spider beetles, and weevils. Aside from different types of beetles, the most common confusion is between ticks versus bed bugs. In any case, since a tick is an eight-legged arachnid, you can quickly differentiate by the number of legs, as all insects have six legs.

Yes, you should wash your sheets and clothes immediately after receiving a pest control service. If your pest pro sprayed chemicals inside your home, it’s important to remove any lingering residue from your washable items. Consult your pest control pro for a list of post-treatment steps to follow.

If there is food sources and other places to build a nest, wasps may come back after their nest is gone. However, if you take measures to repel wasps, like planting pest-repellent plants or sealing cracks and gaps around the outside of your home, they aren’t likely to return. Be diligent at checking for new nests each spring to get rid of them as soon as possible and prevent bigger swarms of wasps in your yard.
