idk,,,,,,, it's mostly just a matter of not having my bed too close to the corner (not pressed up against it), as well as steaming/vacuuming the bed every time we change the sheets, but i had to stay at my grandparents house in indo and the bedroom i was in had the little fuckers hiding out SOMEWHERE,,,,,,, so no matter how tightly i wrapped my fucking blankets the stupid little shits managed to bite at my leg and disappear off into the ether,,,,,, and it was a whole month of getting the most irritatingly itchy bumps that would last at least a week almost every second or third day and it pisses me the fuck off
