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.
