Signs

Do you have spiders in your home? The most obvious sign is that you actually see spiders in your home. Another common sign is the presence of spider webs. Keep in mind that spider webs and cobwebs are not the same. Cobwebs are unused webs that are old and dusty. Spider webs, on the other hand, are actively used. They can be found in various parts of the home, including corners, along ceiling beams, chandeliers, behind furniture, and in open containers.

Here are some other signs that you might have a spider infestation in your home, business, or yard:

• Egg sacs. Egg sacs can be found in webs, crawlspaces, and containers. These small white balls may contain hundreds of baby spiders. Just one egg sac can lead to an infestation, so you need to get rid of these sacs if you see them. Store-bought sprays can be useful, but your best bet is to hire an exterminator.
• Droppings. Spider droppings are not noticeable like say, dog or cat poop, but they can be a sign of spiders. Spider droppings are small black dots that look like black paint splatter. They are often found in attics and corners of your home.
• Moist and dark spaces. Spiders like to lay their eggs in dark, muggy areas of the home. They also like places that have a lot for them to eat as well as places that have minimal human traffic. That’s why basements and attics are common places for spiders to hide, seek out food, and live.
• Flying insects. If you have flies, mosquitoes, moths, and other flying creatures in or around your home, you can bet that you have spiders, too. Spiders love eating these bugs, so be warned that you probably have a spider or two hanging out waiting to feast on these yummy pests. You’ll likely find spiders around light sources, windows, and corners.

Dangers

Most spiders are venomous, but only two species are dangerous to humans: the black widow and brown recluse. Spiders do not actively seek out to attack humans, but they may bite or sting if scared.

When a spider bites or stings you, it can cause swelling, itching, pain, and blisters. In some cases, spider bites can cause allergic reactions, which may require a hospital visit. The black widow and brown recluse are the worst, though. Black widow venom packs a powerful punch of neurotoxins. The cytotoxins in the venom of the brown recluse spider can cause tissue damage and infection. The good news is that these bites are rarely fatal. You should still seek medical attention if you get bitten by one, though, as the risk of infection is still high.

Unlike mosquitoes, spiders do not transmit diseases. A spider infestation in your pantry or kitchen could contaminate your food, though, especially if the spider is poisonous.
