its the humidity. u have to get urself a dehumidifier or keep all your windows wide open. your choice. an air conditioner dehumidifies too...but ud have to keep it on almost all day to keep the room dry...i keep 3 fans and an extractor fan running in my bedroom at all times...im not using the ac in my bedroom this year. i keep the windows wide open too. if your walls are painted and you wipe those bugs down, they're gonna stain the paint. its best that you just lower the humidity. hope this helps
