These things can leave eggs anywhere. I used a $30 eye clops from target and found eggs on a house shoe. ( I don't wear shoes in the house). These are indoor shoes only. I contained the shoes in a plastic bag and now the eggs are hatching. With the microscope I can see the eggs are clear and the fibers in side the egg along with tiny squares within the egg. After 1 week the eggs are beginning to hatch and the fivers are trailing out of them from larger to small at the end. It appears some tiny bug came out of them. Things are moving in the bag and I am going to need to find a glass jar to contain them in. This is why people get better on meds then worse again. There are microscopic eggs waiting to hatch and invade people. There must be larvae in there because a parasitologist at the local university found one on my sample.
That is what the pinpricks are. The larvae hurt when I pressed down on the tape. -- And to really minimize the crawly feeling use clear packing tape, press down lightly, remove, toss, and sleep and fell normal until the next set of eggs hatches.
