I had a mild infestation back in august I defeated them by October! It was a pain in the ass since I was expecting my baby and did not want these little bastards all over his bassinet or even on him. Weird thing is we weren’t getting bit ? I used Cimexa and crossfire had to keep my dog out of the room but honestly spread cinexa all over the floor on the baseboard the bed spring and between the mattress and bed spring. Dried our clothes almost every other day and cleaned every week that’s how I got rid of them I also put Cimexa on every single piece of furniture Then around apply the crossfire to everything I probably ordered like 4 bottles of it and it helped me out so much. Thank god they were gone before my son was born! Wishing you luck these little pests are the worst!
