Spider & Fleas
Spiders and fleas are notorious for being hard to find in your home. They're especially good at hiding in hard-to-reach places. While spiders help to control other insect populations, there are some species of spiders that are dangerous to have in your home. Fleas may not be annoying to you, but when your pets scratch, a large number of flea eggs can become hidden in your carpets, pet beds, and furniture.
