We recently received this message from one of our readers, “I have these worms all over my front porch. When I get rid of them, there’s a new batch the next morning. I also find them on the back porch eating dog food. I find them in varying sizes but they are mostly about a quarter of an inch. They are black and feel velvety. They have six legs and an orange head. As far as I know they don’t bite. I’m very curious about what they are.” The first photograph shows a bunch of these “worms” in a purple bowl:
ATTENTION: GET PARASITE HELP NOW! At All About Worms we get a lot of questions about skin parasites, blood parasites, and intestinal parasites in humans. Because we can't diagnose you, we have put together this list of doctors and labs who understand and specialize in dealing with parasites in humans! That resource is HERE
In addition to having all the features our reader mentioned, these specimens also have segmented bodies. We don’t think these are worms, we believe they are soldier beetle larvae. Among worm-like organisms, soldier beetles and their larvae have shining reputations. Unlike common garden pests, adult soldier beetles don’t eat plant leaves and therefore don’t damage plants. In fact, they actually eat pests such as caterpillars and aphids, which helps protect plants. And they do more than just that… In addition to garden pests, soldier beetles feed a little on pollen and nectar, so they also help to pollinate garden flowers! Finally, soldier beetle larvae feed on the eggs of caterpillars and other garden pests that live underground!
While we are confident about the identification of the creatures on our reader’s porch, we aren’t sure what exactly they are doing there. We do know that the larvae sometimes end up inside homes during the fall, but the reasons behind this are still unclear since they aren’t household pests. The best way to keep them out is to caulk or repair all cracks and to sweep out any that do crawl in. We wish our reader the best of luck while dealing with these beetle larvae and encourage her to remember that they are actually doing a lot to help her yard and garden!
