Tiny bugs in my guineapig cage?
i have recently noticed that there are a lot of small bugs on my guineapig cage. I've checked the guineapigs for the bugs but they don't have any on them. the bugs also only stay on the bars of the cage, they arnt inside the cage. I've washed the cage and the piggies but the bugs still come back. there are also flies in my room, about 3 of them. these bugs are brown in color, have wings and are no bigger than 1mm. they are not lice, or mites or flies. they don't match the description. any ideas? sorry for the long question. thanks!
