Any other advice? I know I should probably get the pros in but I'd imagine they are going to be very costly. Anyone have any idea how much they charge?
Strange that after all that effort that you never actually saw a bug, mine were mostly resident behind headboards and would make their way to the bed during the night, but in my hours of hovering, stripping, boiling etc I did frequently see them on or around the bed, or in the seams of the mattress’s. You should also find little blood specks on the bed clothes from when they bite you.
If you never seen them and there are no blood specks, then it is probably not bugs.
I fought these bugs for 8/9 months, you can find the adults and get rid of them but I believe they lay their eggs deep in the mattress fibres so will not hoover or steam out, you think the problem is solved, and they appear again.
I eventually got Rentokil who took maybe 90 minutes for 3 consecutive weeks spraying all beds, mattresses, headboards, sockets, skirting’s etc, that was about 4 years ago and cost around €500, others had quoted similar prices over the phone.
A lot of money, but it was worth it, no problems since.
