Its not a joke. If its very chronic infestion, no normal pest control can clean them.

I know because i dealth with them before. In the end, i gave up and moved out from house.

Damn bed bugs. First time I had to deal with this it drove me suicidal.

Anyways, since it was a company apartment and we had Rentokil as our pest control for the office, we contracted them to carry out the bed bug treatment as well. Based on experience, while I believe it did mitigate the issue, it did not do a 100% job as bed bugs are notoriously hard to kill. Best treatment would be to fumigate the house and leave it unoccupied for months is what I read. I eventually gave up and moved to a different unit after that.
