I believe these are droppings (or hangings) from box elder bugs that are stuck to the camper. Darn bugs go up and hide under the cover in fall and make a mess
I tried to washer the camper today and I have to scrape each one off with my fingernail and there is still a spot there. Soap and water doesn't touch them.
Any one have any suggestion? I don't have Awesome, will have to pick some up (have black streaks) soon.
There are thousands of these things stuck to the outside- to remove each one would take forever
Hopefully the pic will show size compared to tail light.
