My vacuum became infested with moths...got a new baq, but I can see lots of old grit, possible larva inside the rubber tubing going around bottom of vacuum.. I have gotten a lot out with a toothpick, but there is still more. We keep getting a few moths a day, so I believe there are still moths hatching from the stuff in there. Checked the manual online, but there is no reference to removal of this part. Can I do so and safely pout it back after I clean it?
