Grub-like Gray Worms Found in Ceiling Light are Potentially Wasp Larvae

“These are in our ceiling light”, states this reader about the semi-transparent, gray larvae-like creatures pictured below. “We recently had our home treated for wasps and rodents in the loft.”

Additionally, our reader mentions that “there’s a hole in the roof the property company hasn’t fixed since July.” We assume she mentions this to suggest that the worm-like creatures might have come through here, and we would agree with this. Unfortunately, we are not entirely sure what these worms are, as we have not seen anything quite like it.

The clear skin and visible entrails remind us of flea larvae, but these are far too big, and are gray in color (which flea larvae are not). Alternatively, these could be grubs of some kind. The term ‘grubs’ refers generally to any species of beetle larva. Their plump, segmented bodies reminded us of beetle larvae, but the lack of prolegs does make us doubt this conclusion as well.

Now, our reader did mention having her home treated for wasps, so it is entirely possible that these are wasp larvae, though what they would be doing in the ceiling light I do not know. Perhaps some wasps carried them there when they sensed that their home was being attacked, though we do not know if this is typical wasp behavior.

In any case, it might be a good idea to contact a professional to come and take a look to see if the wasps are still present in the home, and to check for other possible infestations (there might be more of these larvae roaming our reader’s home). Either this, or she could take the larvae to her local county extension office to get a second opinion on the creatures’ identity. Regardless, we advise handling the larvae with care, and using a dustpan to scoop them up onto, so as to avoid crushing them.

To conclude, we are not entirely sure what it is our reader found in her home. In any case, the large number of them may indicate that the wasp infestation is still ongoing, or that she is experiencing an infestation of a different kind. Since she has already had issues with wasps, and dealing with them alone is not advisable, as it is not safe, we suggest that she contact a professional to take a look at this issue. Although we were not able to provide a concrete identification, we hope that this article proves helpful to some degree. We wish our reader the very best.
