Up here on redground the mosquitos have been terrible. And yes it's been very dry, these are night time bitting blood suckers. We all think they are some mutant type. Some govt health workers came by looking for breeding grounds I told them their breeding in the bathrooms. I kill a half dozen or more everynight in the bathroom then in my bedroom. A strong fan and cover sheet do the job for me I stay away from toxic chemicals and such. Those coils make me sicker than the bugs do. I don't know for sure if these are the disease spreader type but I do know they tend to only bite at night. Bless up and don't scratch too hard.
