Pest Control FAQs, answered by experts

Citrus scents such as lemon or lime are lethal to bed bugs. They’re drawn to the smell, but the chemicals often kill them. There are other ways to kill bed bugs without an exterminator, including using steam, DIY heat treatments, essential oils, diatomaceous earth, and more. However, you should hire a professional bed bug exterminator to eliminate large numbers of bed bugs.

For years, it was believed that hobo spider bites were incredibly dangerous, causing flesh-eating wounds. But the rumors of their bites were greatly exaggerated, and there's been no real evidence showing a connection between a hobo spider bite and necrotizing wounds. 

That said, the spiders can and do bite, usually as a defense response. They won't attack you unprovoked, but if you take them by surprise and get close enough, they may bite you. Their bites may cause some minor irritation or itchiness. 

It can be difficult to know what type of animal is in your attic until you see it. But several clues can help you narrow down the suspects:

  • Sounds: Smaller animals like rats and mice make scurrying and tapping/gnawing sounds. Larger animals like raccoons and opossums make louder clambering noises. Also, note when animals are noisy: Squirrels are active during the day, while rats are busiest at night.

  • Droppings: Rats and mice leave small, rice-shaped droppings (the rat’s version is significantly larger). Bigger droppings belong to larger critters like raccoons. As long as you’re not squeamish, an image search can help you identify what you’re seeing in your attic.

When in doubt, take photos of damage or other evidence and show them to an experienced pest control pro.

Groundhogs are definitely cute, but it’s usually not a good idea to have them living in your yard. Not only can groundhogs tear up your grass and create unsightly holes and burrows, but they can also carry infectious diseases that are dangerous to humans.

No, you should never vacuum or sweep up mouse or rat droppings, as doing so can release harmful particles into the air and increase your risk of disease exposure. Instead, wear gloves and a mask, spray the droppings with a disinfectant spray, let it soak for a few minutes, and then carefully wipe them up with paper towels. Afterward, disinfect the area thoroughly and immediately wash your hands when you’re done.
