You should just clean your house thoroughly with water and vinegar, 50/50. This will disinfect and deodorize everything, and neutralize all the odors that attract insects. Clean whatever is infested once and for all, put it in the sun, shake it out and clean it every day or as often as possible with 50 % vinegar and 50% water. You should use more vinegar, if possible, if you can bear its smell. And you have to spray your window frames and door frames with an insect repellent, a harmless one, outside your house. Then the insects won't come in later. Otherwise, they will keep coming in all the time. You should spray them once a week or every once in a while, and then they won't come in. And you must keep yourself washed and clean and hygienic. Then they won't have the grounds to breed in your house.
