Yesterday I saw a bed bug in my curtain (first photo). I spent the whole day looking for their nest; my room isn't very big. The only place I could find was in the upper left corner of my bed, between my sheet and mattress protector, with stains, eggs, and a baby. There are no stains on my bed, and I'm surprised because my bed and bed base are only about two months old. I have a cat, and to avoid harming her, I'm thinking of treating a very limited area with insecticide, around the bed and other places she can't reach. Could this really be an early infestation caused by clothing, bedding, etc., or do I need to resort to more aggressive methods?
