The legs are banded light and dark, the body is grayish yellow with three stripes running the length of the body. They are 1 to 1 1/2 inches long, but appear much longer at 3 to 4 inches when you factor in the legs and antennae. The last pair of legs on the female are twice as long as her body, making her appear much larger than males.
I've found several of these at work in our basement and working in a museum I must say I am glad they are there. Nothing worse that carpet beetles for the welfare of museum mounts and other displays. House centipedes routinely feed on a variety of arthropods, including silverfish, firebrats, cockroaches and the larvae of the carpet beetle (which wreck havoc on taxidermy and insect collections). They also readily feed on bedbugs, and with the resurgence of bedbugs in recent years all I can say is YAY! The one pictured here was found upstairs at work today not far from my office door. Not sure what caused it to venture up from the recesses of the basement, but climbing stairs would be exceedingly easy for them as they can scale walls with very little effort. Maybe it was seeking food or moisture. I was able to capture it and take a few pictures, and came to the conclusion this one is probably not long for the world as it was barely moving. Normally these creatures are insanely fast and quick to dart away to a safe hiding place. Because of their erratic, quick movements many a person have ran in terror from them. Several weeks ago at work I was standing in the kitchen with a co-worker when she shrieked and jumped, which startled me and made me jump, when I looked to see what caused her distress I noticed one of these little terrors crawling out from under the microwave....or should I say sprinting out from under it? I rescued the little troublemaker and released it somewhere safer than our kitchen.
Typically people want to know if they are harmful to humans. They have venom which is delivered through modified legs, so they basically sting their prey to impair them. They possess eyes, but seem to rely on their antennae to "feel" their environment and to find food. Their jaws are considered too weak to do much damage to humans, but occasionally a bite will occur and it is no worse than a bee sting. Naturally if you are allergic to bee venom; the venom of any arthropod could be potentially problematic and you should seek medical care.
If you are finding an excessive amount of them in your home, it could be you have a large pest problem. Getting rid of their food source will often result in them leaving on their own when food sources are not adequate enough to sustain them or their offspring. You may also try using a humidifier and drying up the area where they are found. They do not tolerate dry climates and need adequate moisture to survive. However a few of them is not a serious problem and should be considered beneficial for the free pest control they are providing.
Very interesting article. Our local kind of house centipede has a much lighter color. I was curious about trying to breed them to see the eggs and babies. Like you, I an surrounded by people who want to squish 'em on sight, but they really are not bad at all.
ReplyDeleteI saw one of these in the house of a friend in South Carolina. I let him be, figured he was harmless. Fascinating info, I have never seen one up here in Missouri.
ReplyDeleteI just found one in my house today. As I just moved to MO from CA, I am thankful for your article. I don't have to fear them other than the fact that their prey might be here! Haha
