What Is a Spider Cricket? 5 Facts About the Basement Pest

If you’ve never seen a spider cricket before, consider yourself lucky. As its name suggests, this long-legged insect resembles a cricket with a bit of spider thrown in. They like to hang out in cool, dark, damp places like basements and crawlspaces, where they can be incredibly creepy to encounter because they’re pretty large bugs that seem to be all legs and antennae. They’re often mistaken for huge spiders and have the unpleasant habit of jumping directly toward you when you startle them. So if you’ve spotted them around your home, you have our sympathy.

Here are our best tips for getting rid of spider crickets, plus information about why they might be hanging around and how you can discourage them from returning.

1. A Spider Cricket Isn’t Actually a Spider…or a Cricket

Good news for anyone with arachnophobia—despite their name, these pests aren’t spiders. Instead, they’re part of the insect order Orthoptera, which means they’re related to grasshoppers, locusts, and other crickets (like the black crickets you may have seen around your house and garden). The “spider” part of their name comes from the way their long legs make them look, but they’ve only got six of them, not eight.

And though they’re not spiders, they’re not technically crickets, either. Spider crickets are closely related to true crickets but belong to a different family called Rhaphidophoridae, while true crickets belong to Gryllidae. They’re strong jumpers, thanks to those long legs, but they don’t have wings, and most species of spider cricket also lack inner ears, both of which true crickets have.

2. Spider Crickets Have a Variety of Names

Spider cricket may be one of the most commonly used names for these bugs, but it’s not the only one they go by. They’re also known as camel crickets because of their humped backs. Sometimes they are called cave crickets, thanks to their preference for living in dark, damp places.

3. Spider Crickets Don’t Chirp

Another characteristic that separates spider crickets from true crickets is their chirping ability (or lack thereof). They can’t chirp at all, which, depending on your point of view, could be good or bad. They won’t keep you up at night by making noise the way regular crickets might, but on the other hand, you won’t know they’re inside your house unless you happen to see them.

4. Spider Crickets Don’t Bite (Technically)

Do spider crickets bite? The short answer is no. They don’t. The long answer is a little more complicated. Their mouthparts are built for chewing, not biting, and they will gnaw on just about anything, including fabrics, wood, cardboard, plants, and even each other. If one were to land on your bare skin, it might try to give you a test nibble. While that wouldn’t break the skin, it would still be painful.

5. They’re More Common East of the Mississippi River

You can find spider crickets in states west of the Mississippi, but you’re more likely to encounter them in the east. Some species are native to the United States, but others are native to parts of Asia. According to a study in 24 conducted by researchers from North Carolina State University, the greenhouse camel cricket from Asia was the most common species in the United States, with 90% of respondents reporting sightings of it over other species of these insects. The researchers found that they were more common in and around homes east of the Mississippi and estimated that 700 million spider crickets of all species could be in the eastern United States.

How to Get Rid of Spider Crickets

These pests like the cold and damp, so unlike other insect invaders, they usually make their way inside when the weather is hot and dry. You’re most likely to see them indoors in the summer and fall. Unfortunately, if the conditions are right, they can breed in your house anytime. They’re not picky about what they eat, so once inside, they’ll have a convenient buffet to feed on, including fungi, wood, cardboard, fabrics, and pretty much anything else they can get their mouths on, including other spider crickets.

The best way to deal with spider crickets is to keep them out of your home in the first place. Basements and crawl spaces are popular hangouts, so seal and weather-strip openings at the lowest levels (like basement windows and ground-level doors). If they’re still getting in, a dehumidifier ($249, The Home Depot) can help dissuade them from sticking around by making the air less damp. Cutting clutter and cardboard boxes will also help eliminate hiding spots and food sources.

Another line of defense is sticky traps designed for mice and other household pests like the Tomcat Super Hold Glue Traps ($5, Walmart), but a few loops of duct tape will also work similarly. Place these where walls and floors intersect in basements and other places you have encountered these creatures. They’ll often accidentally stumble into them, but you can increase your odds of catching them by adding a few pieces of bait to the center of the tape. They love fungi, so a moldy piece of bread could work. When they go after the bait, they’ll get stuck and die. Once you’ve caught a few, the dead ones stuck to the trap will become bait for these little cannibals, too.

Shallow bowls of soapy water left where you’ve seen the crickets can also be effective traps. Especially if you’ve already tried to reduce the moisture in your home, the crickets will be attracted to the water. While trying to drink it, they’ll drown in the bowl.

Organic Pest Control Solutions

If you don’t want to get close enough to squash them (we don’t blame you) and you’d rather not have to clean up traps loaded with cricket corpses, use a strong vacuum to get rid of them. Just make sure to empty your vacuum cleaner immediately afterward in case they survived the trip and try to make a reappearance.

Spider crickets may look terrifying, but luckily, they’re not too different from their true cricket cousins. You can keep most of them out with a few preventive measures and catch any that slip through your defenses with simple traps. However, if the spider crickets in your home escalate to the level of an infestation, calling in professional help could be your best bet.

Frequently Asked Questions

  • Can spider crickets harm your home?

    Spider crickets feed on almost anything they can get their mouths on, especially fabric, wood, fibers, plants, cardboard, fungus (their favorite), and more. While they won’t cause damage to your home’s structure or foundation the way termites or carpenter ants might, they have been known to chew through rugs, canvas, linen, drapery, and other such items. They can also leave behind dark droppings (“frass”), which may stain walls, surfaces, and fabrics.

  • How long do spider crickets live?

    Spider crickets have a lifespan of about one to two years. They tend to gather in large groups and will often lay eggs in the spring and then overwinter as young nymphs or adults.

  • What home remedies help repel spider crickets?

    The best way to repel spider crickets is to make sure your home is dry and well-sealed. Seal any cracks or openings with caulk or weather stripping—particularly on the lowest level—and use a dehumidifier in dark, damp spaces to make the place less comfortable for spider crickets. It’s also a good idea to move any piles of bricks, wood, leaves, and stones where moisture could collect away from your home.
