I need some gauranteed remedies to either bites or to stop the blessed things invading our home - this morning I killed more than a dozen in my sons bedroom alone and he has upwards of 50 bites infact his teacher thought he had Chicken Pox at school today ! ( she has no children and doesnot know they are blisters you get and not spots). My youngest son and myself very rarely get bitten. I have tried lots of things lavender, spraying the bedrooms with fly killer, hanging insect killers, insect repellent and we still seem to be being bitten - anyone got any bright ideas.
