Tips for Identifying Dangerous Spiders

What do you do when you see a spider in your home? Some of us leave it alone, hoping it will just hang out and catch bugs and not be a nuisance to our daily lives. Some of us kill it right away because they might be dangerous and creep us out anyway. But there are ways to see if a spider is dangerous or not, so you don’t have to worry if it will harm you or your family.

Most spiders are as harmless as a ladybug. Similar to how ladybugs can help your rose garden by eating harmful aphids, spiders can help your home by eating insects that may be harmful or annoying to humans, like fleas, mosquitos and flies. If you know how to tell if a spider is dangerous, you might be okay with leaving it alone to eat those other pests.

Here’s some information about which spiders are dangerous and which are fine to leave alone:

Daddy longlegs

One of the most commonly found spiders in the United States is the daddy longlegs. It has a small body with exceptionally long legs, hence the name. It is not poisonous and does not even have any venom glands. It’s not even a true spider, technically, since the three identifying parts of a spider—head, abdomen and thorax—are fused together in this species. These can be left alone, and they will not be a bother to you.

Black widows

One of the most widely-known dangerous spiders is the black widow. While both the male and female are poisonous, the females’ venom is three times more potent than the males’. Black widows are common across the United States, and a bite from a female black widow can be deadly. If you are bitten by one, you should seek medical attention right away.

Black widows are easily identifiable. They grow to a body size roughly equivalent to a quarter and are all black with a red hourglass shape on the bottom of their abdomen. They are often found in woodpiles, stone walls, garages, sheds, basements, crawlspaces and sometimes in outdoor furniture.

Yellow sac spider

Another dangerous spider—though not deadly like the black widow—is the yellow sac spider. This spider is common throughout the U.S. except in Maine and the inland Northwestern United States.

It has a venomous bite, but the venom is not fatal. It can be identified by its pale color, usually ranging from yellow to beige. It has dark tips on each of its legs, and the front pair of legs will be longer than the others. It typically lives in corners where the ceiling and wall meet, as well as behind picture frames, along baseboards and in wood piles or other undisturbed areas.
