Ours is a battery operated machine I do not think it is vape.

It is a small green thing and it emits a hi pitched sound when you turn it on. Supposedly the sound keeps them away, but we have not had any in our apt so far to test this out.

I think the fact that the winds have been light (and sometimes from the back of the island) that it may have something to do with the little P.I.A's swarming around lately. I know they sure like the taste of my legs and arms.

There are some guest that are staying in one of the units in our complex (Bermuda Landing) that actually drove a golf cart to Capricorn for dinner the other night......by the time they got back they were both missing a few pints of blood because of the mosquitos! Not a smart thing to do.

Vape Mate works. How comes I didn't see them back in the US?

Same reason you cannot find Dursban in the US, I think.

From the package "Mosquitoes will be killed by the pleasant perfumed vapor produced by the heater".

Doesn't say what the active ingredient is but they're manufactured in Indonesia.

Found this interesting list from 2005 of pesticides registered in Belize: http://www.pcbbelize.com/forms/pesticides_register.pdf

Vape mats are shown as prallethrin.

Another good link: http://www.pesticideinfo.org/Detail_Chemical.jsp?Rec_Id=PC35755

Noted that prallethrin is not banned in any country. Just a case of marketing is probably why it's not in the US.
