I have these little yellowish grub type worms crawling up my walls, I had to remove the ceiling tiles to get at them. Every morning and every day I get home from work I collect anywhere from 15-30 of them and I have no clue where they are coming from. What little food I have in my house is all sealed and they’re not coming from my trash can. Usually in the morning I find them hanging by I guess a web they make off the ceiling. It’s been a week now and I can’t get rid of them. They’re just more of a nuisance now. They have little legs and a brown head. I think they are forming into these little brown moths of some sort because I seen a couple flying around.

Got a some kind of bugs in my kitchen. They navigate toward the ceiling. I collect about 15-30 every morning and when I get home from work. Don’t know what they are, where they’re coming from or how to get rid of them.

Dear Steele,
We hope you are not irritated with us for not responding yesterday.  We had a very busy day doing public service planning and organizing a ten year anniversary commemoration of Heidelberg Park and we did not answer as many letters as we do in a more typical day.  We believe these are the larvae of Indian Meal Moths, or Indian Mealworms,
Plodia interpunctella.  See BugGuide for verification.  They infest stored grain products like corn meal, oatmeal and even pet food and bird seed.  You are correct that they metamorphose into the moths you are finding.  We suggest you thoroughly search the pantry for the source of the infestation.  If they are appearing in the numbers you indicate, the infestation should not be too difficult to locate.

Thank you very much!! That is what they are!!! Now I just have to get rid of them.  Guess I have to trash what little food I have in my cabinets!! Thank you again!! And I am glad that you offer your help for people like me! I searched all over google and couldn’t find a thing to what they were.

  1. I have a very similar worm/catapiller showing up at my home in Dunedin FL but never on the wall or ceiling Only on the floor in my front hall. I see this 2 to 3 times a day. The body is a little more orange in color but not far off from this worm. Any idea what it may be ? It appears to be coming from my door area.
