Sorry for posting in AIBU but I was hoping for traffic.
I seem to have a miniature centipede infestation. Tiny black wriggling things. I cannot tell exactly where they are coming from. I have heard it is because of damp. I have had my roof fixed after storm damage so I'm hoping the damp will be gone.
Is there something I can spray into cracks (smaller than grout size gaps) to deter them even though I'm loathe to kill anything?
Ripping out walls is not an option. They are very small and I think they must emerge at night as I have never seen one "arrive" just find them when they have crawled somewhere presumably in the search for food?
