Wasn't sure where to post but is this a mosquito bite? DS has been getting bitten in his bedroom. I've checked all his bed/sheets etc and no sign of bedbugs (also assuming they'd have spread to us all by now). We did have fleas on the dog but that's all cleared up and the (small!) house has had 6 tins of Indorex, hoovered, everything washed on 90°. It's only DS that's getting bitten and only in his bedroom (DDog doesn't go upstairs). The bites aren't in clusters or lines. They come up like a welt with a red area around them, then calm down to red marks. It's been going on for a couple of weeks now and I'm pulling my hair out!!
