Some gratuitous advice for anyone who’d like to get rid of the little bastards.
Camel crickets (also known as sprickets because they look like spiders) feed on fungi that grow on damp basement walls. When they can’t find fungus, they are reported to eat carpet, cardboard, wood, and each other (you really didn’t want to know that, did you?). There’s even an Australian species that eats one of its own legs when sufficiently hungry (watch the video, if you dare). There are hundreds of different species of camel crickets, but they cannot be distinguished by number of humps — they all have just one. Note that camel crickets are different from cave crickets. Unless you live in a cave, you have camel crickets.
Camel crickets often hide during the day, but you can tell you have a large population when their frass colors walls dark brown. (Frass is poop, by the way — if you watched Sideways, that’s why the name “Frass Canyon Vineyards” is so darn funny.) If your population is really large, mice will likely move into the basement to feed on the crickets, and then you have a mouse problem, too. When the crickets migrate out of the basement in search of food and moist places to lay their eggs, they tend to creep the bejesus out of unsuspecting family members … which is why I was motivated to make this page.
Some ways to get rid of them
1. Make sticky traps out of duct tape, then bait with a piece of dry cat food or equivalent. Any food works. Indeed, once the first cricket gets stuck they’ll all be on that trap trying to eat the first guy even before he’s dead. If you’re too lazy to make your own sticky trap, just search for “mouse sticky traps” on your favorite online retailer, or buy them at a big-box home improvement store. If you really hate your camel crickets, buy dozens of these traps. They will fill them.
If you like doing stupid science projects to impress your friends, put different types of bait on the traps. Let me know what works the best. If you have kids, pit them against each other with the challenge of choosing the most effective bait. You can somehow reward the one that comes up with the most crickets at the end of the week. Or you can punish the loser — depends on your parenting style!
2. Place containers of soapy water in your basement. Camel crickets love water and will fall into these containers and drown. The soap is just a way to counteract the waxy coating their exoskeletons have, so they sink faster.
3. Buy an electronic rat trap (e.g. on Amazon). These bad boys have enough amperage to cause a cricket to explode. And spark, so make sure you don’t set it near anything flammable. Also, make sure your basement doesn’t have a gas leak. That would be bad.
4. Hunt them with an Airsoft gun. Don’t pass up the opportunity to play music that fits the task, such as the soundtrack from The Descent, Aliens, or Starship Troopers. And use biodegradable ammunition if you don’t want to clean up after the carnage. Unfortunately, the crickets will probably eat the pellets (doh!). Note that if you get a weapon for each member of your family, this can be a bonding experience, and can even qualify for Family Home Evening if you live in Utah. (Family Home Evening is Monday night, just in case you’re not Mormon and don’t know better. Don’t embarrass yourself by doing it on Tuesday. Been there.) Remember to wear safety goggles.
5. If your family is looking for fun but is against weapons, get each member a bug-zapping racket (e.g., like this one). I own one of these and can say that they kill houseflies like a charm. They spark, sizzle, and pop in a satisfying way. The one I have takes 2 AA batteries, which lasts about a month during the fly season.
6. Buy a Siamese cat. We have one of these, named Fleabane, and she is a ruthless camel cricket predator. Hunts them down and eats them, leaving only legs. Kind of creeps us out, truth be told. [UPDATE: she's over this, and is now worthless.]
7. Release mice in your basement. Mice just love to eat camel crickets! And then, to get rid of the mice, go to the pet store and buy one of those giant centipedes from the tropics. Watch this video if you doubt that a centipede can kill and eat a mouse. Don’t watch the video if you’ve just eaten. And don’t watch the video if you ever plan to travel to the Amazon.
8. Keep chameleons in your basement. When I was growing up in squalor in East Lansing, my parents bought two chameleons to keep the roaches at bay. They just had the run of the house (the chameleons, that is). When I was young, I thought everyone had chameleons for this same reason (ah, foolish youth). Anyway, I’m sure they’d eat camel crickets. Just make sure to give them a heat lamp and a water source.
9. Attack them with a weed trimmer. My family used a weed trimmer to control snails in our vegetable garden when we lived in Salt Lake City, and it was great fun. “Great fun” for a teenager in Salt Lake City is probably a questionable phrase, but I do have fond memories of this. I’d wear safety goggles so the juices and shell shards wouldn’t get in my eyes. The big problem with doing this in your basement is that the cricket juice and attached limbs will just get sprayed all over the walls, and then you’ll have that to deal with. Of course, the camel crickets left alive will slowly eat the surfaces clean (I’m an optimist).
10. Buy a Roomba vacuum bot. Ideally, attach food to it so the little devils actually move toward it. Or put food in the center of your basement in a way that is protected from the Roomba, then let the robot loose.
11. If you have a spare vacuum … buy a Belkin WeMo motion switch (at Targét!) and set it up next to a secured pile of food. Then plug your vacuum cleaner into the power switch component of the motion switch (which will get activated by the motion) and position the vacuum attachment tube really close to the pile of food. If your basement is dark, also set up a little battery-operated, motion-sensing light so that cricket movement causes the little area to be illuminated enough for the motion sensor to work. Then use the Belkin smartphone app to make 2 rules. Rule 1: when motion sensed, turn switch on, then off immediately (this sucks up the cricket and returns unit to sensing mode). Rule 2: when switch activated, send notification (this tells you that a cricket has been sucked). Rule 2 isn’t really necessary, but it sure is fun to get those notifications on your phone during a boring meeting. You can silently whisper, “Yessssss. Yea, life sucks, you creepy little bastard. Die, die, die.” If you’re really Type A, you can link up the device with IFTTT so that number of sucks per day is recorded in a spreadsheet. All of the above details are illustrated in my post, “Using motion-activated vacuum cleaner to control camel crickets.” There’s even a movie. Yes, I’m Type A.
12. Spray with chemicals. Camel crickets are insects, so any broad-spectrum insecticide will work. But this is a lame remedy. If you make your basement too toxic, you can’t lock your kids down there.
13. Waterproof your basement. Once you cut off the moisture supply, you cut off of the fungal growth and the crickets will starve. This is actually what I’ve been doing with my spare time, and it turns out it’s a lot of work, which is why it’s way down on my list. I’ve gone through about 700 lbs of cement already, plugging gaping holes in the foundation and also applying at least 1/2″ of cement to all surfaces. It really sucks, and it’s actually not doing a whole lot to control my cricket population. They just watch me from the dark corners and laugh. And my back hurts.
14. Move to a different house. This is a really attractive option for me. Our town’s nickname is Swampmore. I should’ve known better.
