I had them back in 2012 in a townhouse we rented. Took almost two years of treatments. We would get treated and be fine for about 6-8 months and notice them again. It wasn’t until I begged the landlord to inspect the neighbouring units and that all were treated that we finally got rid of them. The fuckers can travel through walls and make lives incredibly difficult and irritating. Over a decade later and I still have PTSD about them.
