On random occasions I seem to get insect bites on me a bit like mosquito bites. We do have a cat but she's always flea treated, doesn't come upstairs anyway and isn't constantly scratching.
I have them on my neck, knee and feet today but only ever me who gets them! I used to get them from work too (office job)
Any ideas? We do have a relatively clean house so it's not like we're breeding all sorts of nasties
