Pest Control questions, answered by experts

The time it will take to see results from a professional exterminator can vary depending on the type of treatment and the severity of the infestation. You may notice a reduction of ants within a few days, but it can take weeks to months for the treatment to take full effect and kill the entire colony of ants. Make sure to discuss what results you can expect with your exterminator and any post-infestation cleaning you should do after the treatment.

Paper wasps look similar to other wasps, like yellow jackets. They have narrow, but not thread-like, waists with black or brown bodies and yellow colorations. You can better identify paper wasps by their nests, which are made with regurgitated wood pulp. The nests look like they are made from paper and usually have visible hexagonal holes, like a honeybee hive.

They build their nests in places like eaves or branches, and their removal more often warrants the help of a wasp control specialist near you.

Ant and termite infestations look very different. Since termites feed on wood, one of the warning signs of their presence is drooping drywall, peeling paint, loose floor tiles, and crumbling wood. On the other hand, ants feed on plant- and animal-based food options, so you’ll likely spot a colony near your home’s food sources. If you’re unsure what type of pest infestation you have, hire a pest control specialist to inspect for you.

Both insects can damage wood, but there are key differences between termites and carpenter ants that tell them apart. Carpenter ants tunnel through moist wood, leaving behind smooth tunnels and sawdust-like piles, as they don't eat the wood but rather carve it for nesting. In contrast, termites actually consume wood, creating irregular galleries filled with mud and dirt, and leaving behind mud tubes as their signature. In terms of appearance, carpenter ants have segmented bodies with heart-shaped heads and larger front wings, while termites have more oval bodies with straight antennae and equal-sized wings.

Pantry bugs are rarely able to get into sealed packages, but they may try. If you find pests on or around a sealed food item, check inside to make sure the food is still clean. Not sure whether a package is contaminated? Spread the contents onto a cookie sheet and use a flashlight to look for pests.
