Bugs in the bee

One of my favorite paper mache sculptures is a big bumble bee. I made it a few years ago and I'm quite fond of it. It took forever because there are so many external parts to the anatomy. But it was worth the effort. Because it is fairly large, I keep it in my home office/craft room on a little end table by the window.
A few weeks ago I noticed that there were a few piles of gray 'dust' underneath the bee on the table. On closer inspection there were tiny holes on the body of the bee where the dust was dropping from. An even closer inspection, I saw very tiny little bugs--"no-see-um" sized, around the holes. They looked like teeny termites. Were they EATING my bee? How did they get there? Since I would keep the windows open upstairs for ventilation, I think they were so small they got thru the window screens and alighted on the sculpture.
This, of course, freaked me out. I sprayed some RAID insect spray on a paper towel and wiped down the sculpture around the little holes. I then applied some Elmer's glue over the holes, repainted those sections, and painted a new coat of Modpodge over the whole thing. I thought would solve the problem. It didn't.
I put the bee in my bedroom to keep an eye on it. Well, some more dust started to appear beneath it again. Not as much dust as before, but enough to be annoying. On top of that I saw another little bug.
So I decided to take no prisoners.
I brought the bee down to the basement work table over a several sheets of newspaper. I sprayed the body underneath where most of the holes were with a good amount of RAID directly. I let it dry over night. So far I've seen no more dust. I hope this does the trick, I really don't want to get rid of this piece. I put too much work into it to let be destroyed by insects. Stay tuned.
