Well, I live in Florida so as you can imagine it is HOT here it the summer. High 90's and humid. Usually 90%-100% humidity. It's very sticky. It rains everyday without fail and usually around the same time everyday. Lots of mosquitoes, big pesticide trucks drive down the streets at night spraying the mosquitoes. Fleas and ticks are abundant here too. I keep frontline on the dogs therefore I never have a problem with fleas, however I still have ticks, but they aren't as bad as they would be if I didn't use frontline. I loathe Florida summers.
