Yes. While cellar spiders can seem creepy or scary, they’re essential to the ecosystem. They feed on smaller insects in your home or elsewhere, keeping those populations in check. They’re also food for birds and small animals, so if you let a cellar spider live and simply transport it outside your house, you’re letting the natural cycle continue undisturbed. 

The most common wasps are hornets, yellowjackets, and paper wasps. Both hornets and yellowjackets are black and yellow, and hornets are known to be more aggressive if their nests are disturbed. Paper wasps are black or reddish-brown with yellow markings and often build nests on eaves or branches. Of the more than 300,000 species of wasps, these are the most often encountered by pest control professionals.

Possums don’t typically pose a danger to humans—they prefer to stay out of sight. If they feel threatened, they play dead instead of engaging. However, they can become aggressive when cornered, typically when they become trapped inside your home or when a dog chases them. When this happens, it’s best to call a wildlife control service near you to remove possums safely.

Squirrels hate anything that disturbs the peace in their nest. Loud noises, bright lights, and strong smells like cayenne pepper or mothballs will deter them from your attic. Spread these scents, add a strobe light, or use an ultrasonic repeller to keep squirrels from nesting in your attic.
