Fat Black Larvae in RV

A reader wrote to us recently about some plump black larvae he has been finding in his RV after a water leak. At first he only found the larvae under his trashcan, but he has since spotted them in other parts of his RV – “on the bathroom floor and the carpet and around the seams where carpet stops.” We are pretty certain our reader is finding black soldier fly larvae, but that only addresses the first of his three questions. He is also wondering why the larvae are in his RV, and also how to get rid of them.

Black and Gray Larvae that Bite

A reader in Arizona wrote to us about a black and gray larva that crawled into her bed and bit her on the hand. Naturally, this concerned her, and she is trying to figure out what she found. The larva, which is about a half an inch (one centimeter) in length, was a bit menacing in that even after the reader removed it from her hand, it started crawling back toward her, and it was only when she shined light on that it backed away. What type of black and gray larvae might crawl into your bed and bite you?

Small Black and Brown Larvae on Cats’ Blanket

A couple of days ago a reader found some small black and brown larvae on the blanket her cats sleeps on. The cats’ blanket (and therefore the larvae) is lying on a hardwood floor in an undisturbed corner that hasn’t been cleaned for a while. The larvae appear to be limited to this corner, and they aren’t found anywhere else the cats go in the house. The reader was wondering what the black and brown larvae are, and specifically indicated that they might be carpet beetle larvae.

Small Black Worms on Carpet Under Desk

A reader wrote to us recently about some small black worms that he is finding on the carpet under his desk. The black worms are only about an eighth of an inch long and they move quickly. In general, the reader isn’t especially concerned about the small black worms, as he doesn’t “mind them in particular if they were under the bed or something.” However, their presence under his desk is a problem because he is normally barefoot, and he is (understandably) “grossed out by the idea of them being there.” The reader is wondering what the small black worms under his desk are, and he is also wondering if they are dangerous and how he can get rid of them.

Small Black Worms in the RV

A reader from Texas recently wrote to us about some small black worms he is finding in his recreational vehicle (“RV”), and sent us a picture of one that is on his floor. On some days, he finds as many as six or seven of the black worms (which can also be “charcoal grey” worms) in his RV, but he has also gone up to a week without finding any worms. After struggling to discern where the worms are coming from, he finally concluded that they are entering the RV through the heat vents. The reader lives in his RV, and so was naturally wondering what he is finding, and he also wanted to know how to get rid of the black worms that have taken up residence in his RV.

Brown Larvae in the Cupboard

A reader wrote to us a few days ago about some “fat short brown” larvae she is finding in the her kitchen cupboards. (Yes, she did actually refer to the creatures as larvae, breaking with the common practice of calling larvae “worms,” which they technically aren’t, insofar as “worm” has a precise meaning.) The reader found the brown larvae (which might also be described as black) near a dead mouse, which had recently been killed by a trap. The reader speculated that there might be some connection between the two, a reasonable enough assumption that we will pursue below. Although the reader only found two of the larvae, she was still understandably concerned about them. She asked us what the brownish, blackish larvae are, and if she should be worried about them.
