Yep I got the same answer as Rosewood as have others that I know who have called. they only fog if they find a case of West Nile and in the 3 years I have been here they never have. If you have pets, make sure to spray them as well with animal approved stuff (I get a spray at PetCo for $6 a bottle that is natural with Eucaliptus(sp?), tea tree oil and Citronella in it and it works very well on my dogs), and use something with DEET in it for yourself. Unfortunately I didn't even go outside the last 2 days only to wake up with 5 bites on me simply from opening and closing the door to let the dogs out to potty. Yeah they're BAD. Citronella candles, OFF, heartworm prevention and repellent for the pets and hopefully we'll all be good, should only last another 4-6 weeks.
