We have bins and rubbish further down the garden with no maggot there. I’ve watched and they seem to be falling out from the bottom of my PVC door, some are trying to climb up the pvc and come in under my back door. There are literally hundreds of them, I’ve been throwing bleach and hot water out and they’re still coming thick and fast. I’ve never heard of them being anywhere but bins, how will I get rid of the vile fuckers?
