Ok it's getting insane now. There are so many of these little critters in our bedroom that sometimes when I wake up in the morning, I'm mildly surprised to find they haven't set up little houses or a holiday retreat!! The picture attached isn't great so I'll describe best I can...
They're slightly larger than a flea, they scuttle at speed but don't jump. They live along skirting boards and the lower part of the wall and the majority of them are on the inside of the exterior wall. I noticed a few of them a couple months ago, but now there are loads and they've started creeping into bedside cabinets and headboard. I've also seen the odd few in kitchen cupboards so I have no idea what they could be!!
Any ideas? And how can I stop them taking over the house? We are wanting to sell up fairly soon.
Picture attached. Any help would be hugely appreciated.
