Been fighting this nonstop for iver a year you name it I’ve used it everything on here to a t. What has working right now and I figured out and someone else in this sight suggested is switch your method of killing them each week. They get immuned to one thing like premoguard, ammonia, Kleen green, borax. So forth. Especially my clothes is where I noticed it the most. After a week amonia, borax, and I used arm and hammer detergent. Wasn’t working when i first do it it was amazing my clothes sheets so forth. So now o just switched out the amonia to Epsom salt. So switch the way you treat your house, you, and clothes each week. I have moved, been through hell and still battling. But this helped.
