Does a freeze or frost kill them? Fall is on the way and going in the 40's at night. Does anyone know what temperatures they stop being active and also humidify? Like if the dew point is in the 40's do they still come out?

BTW...where are they, grass, bushes, trees ect?

They lay their eggs in water. They live in spots that have moisture. Extreme cold will kill them and their eggs. By keeping the grass short and the areas below our shrubs clear we have managed to get rid of a lot of the ones around our house.

It was great out last night. Used 2 Thermacells in the observatory and one near the door into house. They really work!

In this semi-arid area of British Columbia (the southern Okanagan Valley), mosquitoes are rare. I get buzzed by perhaps six to 10 mosquitoes a year -- just one of the many reasons that I chose this area to retire to pursue my hobby. The air is dry enough that the water in places like eave-troughs evaporates long before larvae can mature and the ground is porous enough that puddles drain away within minutes after a rain shower.

We have lived in other parts of Canada where the mosquitoes were in clouds and you had to run from the car to the house -- just one of the many reasons that I moved from the Atlantic coast (New Brunswick) to the far west.

We sometimes have mosquito problems at our high altitude observing sites in the surrounding mountains, another reason why I usually observe from my dark valley floor backyard observatory. It is much easier to concentrate at the eyepiece without that buzzing!

Consider moving west.

Thermacell is the heat.

Here's my Themacell oops from last night...

Last night I was out observing the Moon. I have a TV-tray that I put my charts and stuff and Themacell on. One of my charts is AstronomyLogs.com's Lunar Field Atlas , which I have in a three-ring binder.

Well, stupid me put the binder down open to a chart and laid the cover right on top of the Themacell. It must have been there for about fifteen minutes.

I realized what I had done when I noticed I wasn't smelling any of the Themacell scent anymore. Well, nothing caught on fire (I don't think it gets that hot anyway), but the plastic cover of the binder was rippled and a little melted and quite hot. Oops.

My only complaint about the Themacell is that it is very easy to forget it is there and you're wasting butane when the chemical is exhausted (mine seem to last just an hour).
