They're simply annoying... and if left on painted surfaces, may damage them. And yes, there's something in those fabric softener sheets that you toss in the dryer that really work well.... and the cheapest ones work the best for me - you know the ones, they look like pressed spider webs or something??? Just grab about 3 of them, scrunch them up, dampen them, and start rubbing those bugs off... they just slide off! Rinse and you're good to go. I pick up a box at the Dollar Tree and leave them under my kitchen sink.... always smells nice in there!
