Had a nice walk in the countryside, through fields or woods and now you have itchy legs and trunk. It could be auta, a miniscule red spider which for some reason in Autumn is very aggressive. One of our dogs is suffering with auta between the paws and boy, does she scratch and lick. Malc and I have both had auta attacks when we first came here and thought we had fleas. Actually we had our brother in law staying with us and he came shamefacedly to tell us that he had caught fleas from our dogs or cats. We ended up going in a threesome to the Doctors for medication as it was so bad, to be told we had suffered an auta attack. We got some antibiotics which quickly sorted it out. We know someone else who fumigated the house thinking again of fleas but it turned out to be auta. So if you have really irritated skin and have had a country walk , it could be those pesky spiders.

I think it is Aoûtat and it is a harvest mite. Checked it up and she is right, thank you Karen
