I dont have a gauge for humidity yet, but I am in NY and, in general, our humidity levels are pretty high. Add summer temps to that and I should be okay (I think). My home also gets pretty muggy and warm inside during the day since it is all shut up while my wife and I are at work. I'll be running out to get some mite stuff today after work, so I will pick up a humidity gauge as well. What level should I be at? Also - any preferred methods that you recommend for treating the mite problem? Thanks so much for your help.
