I used to have these small white worms that would crawl on my ceiling way wack when. I tried spraying my ceiling with Windex...then i went to the store n bought RAID. I sprayed my entire room, shut the door, n left a fan on to circulate the fumes. The next day, ther were no more white worms! Maybe u should spray ur interior with bygon or Raid, n shut ur doors..n maybe leave ur a/c or blower on for 15 minutes.
