>>24053370What i did was put DE on all the seams of my mattress then put a bedsheet over it. I also put it at the bottom legs of my bed frame so they couldnt crawl up it. Then for an overkill measure, i dusted all the baseboards in my room with it, in case they tried to flee and hide out. Next two weeks i find them all over my room belly up. And they never came back.
I also acted immediately when i discovered them which is probably another factor why it worked so well.
