Boat cover damage by bugs

I know this is not directly related to fishing. Just hope to save you some $$$. I brought the boat home last week and set it in garage. I left the storage cover rolled up in back of the truck. I went out today to put the cover on and when I unrolled the cover it had hundreds of what looked like Stink Bugs running all over. I checked the cover and it now has a lot small holes scattered all over the cover.. Just thought I would throw this out there so if you have a cover rolled up somewhere you may want to check it.
