U by Bedsure Bed Bug Proof Mattress Cover Twin Size, Mattress Protector 100% Waterproof for Bed, Zippered Mattress Encasement Six-Sided 15 inches deep

I accidentally ordered 15 inch thick instead of 12 so it's actually too big for my mattress, but I still like it tried to put it on the wrong way at first. It was very surprised. I did not bust the material or zipper and if anybody else looks at it wrong I'll just let you know. It goes on from head to toe not to side lol highly recommend this product a lot more durable than it looks. Shipping was very quick. I've highly satisfied.

Our neighbor downstairs brought bed bugs into the building and we've been struggling to get rid of them and keep them out of our apartment, as he's not doing his part to get rid of them as well. It had gotten so bad that we were waking up from our sleep itching and in pain (I'm especially sensitive to their bites). We had tried diatomaceous earth and insecticide spray under the bed because it worked before at a different residence, but that didn't help this time. Finally, though, a combination of bedding/home spray for the mattress, the encasement, plus Ortho spray and diatomaceous earth, we've had over a week of not getting bitten at all. We're still working on treating the rest of the apartment, but this is a major win in this war! I had researched and found that the TPU material lining the inside of the encasement prevents the bugs from escaping but doesn't suffocate them. Trapped inside for at least 12-18 months, though, they will die of starvation. Keep that in mind if considering this as an option. We plan on leaving the encasement on the bed until we buy a new mattress. I definitely plan on getting another one of these when we do get a new mattress so we don't have to worry about it getting infested.
