Omg; I feel your pain. We had them bad in NY. We moved about a month ago, and treated our cat just before leaving with Feline Advantage.. All of our posessions in a very-hot UHaul trailer must have killed them off, because we haven't seen or gotten bitten in over a month.
But I too was getting eaten alive by them, with no recourse. Tried all sorts of repellants before bed.. tried sprays from the grocery store.. no dice. My cat had been treated monthly with Adv, but the strays from outside were walking by the house bringing them in..
