Sorry I have posted several threads on this topic recently 
We have spent this wonderful summer being eaten alive by fleas. We have no pets and have indorexed and acclaimed the crap out of our house. Washed everything.
No idea where they’re coming from. Had rentokil in twice at great expensive, moved all the furniture, kept the kids out of the house, spent days and days in soft play as couldn’t put DD 7 months on the floor.
Two weeks flea free and I’ve just been fucking bitten twice, I saw the bloody thing! Our childminder just came back from holiday and was in our house for an hour this morning. She has a dog, could she be bringing them in? I had just been out in the front garden, could they live out there?
I am genuinely starting to despair
