Audrey, Tim (5/12/2011) is right. I had the same problem with the property I live at now; an
old chinchbug infestation that threatened to start again. I went to Home Depot, and bought a bag of lawn treatment, with the "Arena" pesticide in it. The Home Depot salesperson said it's the newest treatment. I applied it, according to the directions; end of chinchbug problem....for THIS season!
I live in FL, and the hot air from earlier in the day seems trapped inside, when I want to bring in the cooler night air. I have ceiling fans, but they don't seem to make a difference. Should I use a standing fan instead?
