Do these work??

Has anyone used these for bed bugs and have them actually work. I’ve read some reviews that say it didn’t help at all or it made it worse but I also read that they worked after a couple uses. Just wanna know if anyone’s experienced these? (I would hire an exterminator to get rid of them but because of the size of this house the average pricing for an exterminator is about 1500 dollars which we do not have to spend)
