Ive noticed these for a while now, i find them under the bed crawling along the floor i regularly hoover under beds to remove crumbs etc when we have used the caravan. They are extremly small black midgy type things and im sure not bed bugs as we would be infested by now im sure, as i said ive noticed them for a long time now its 'bugging me' lol i want to know what they could be. Damp problem has been sorted now so the caravan is dryand i know that things can get in as there are vents.................anyway can anyone shed some light on the little critters.................
