Ok, first of all it has been almost 4 years since my husband and myself were able to getaway. We have 4 kids so its hard. We stayed for the weekend in Atlantic City, cannot say name filed lawsuit..Well after the first night we had small bite marks we assumed it was sand fleas, being we were on the beach 1/2 the day..than the next night more and more bites, we than checked the mattress and found the nasty critters, We tossed our suitcases, but still managed to bring them home, I did order a product online made by cidercide which I hope works but it will take 3 days to come..I cleaned entire house twice already and threw out all mattresses, but my clothes, we are a family of 6 and throwing away everything is not going to work..I know i can wash if water is at least 120 degrees, but I don't know if my water is that, I did read I can use diatomaceous earth to also kill, but can I put it in washing machine, We have a pool that is a DE filter and have a whole barrel.. any help would be greatly appreciated..OH my gosh so much wash I think I have to go to laundry mat and use big washers...I must have about 50 loads,,LOL...
