Ken, it's not usually a great idea to nuke your whole yard to get rid of mosquitoes. You'll kill off all your beneficials as well. Have you been treating the standing water areas around the house with Mosquito Dunks?
I go around the house once a month and put pieces of dunks in all the low areas that puddle when it rains, gutters that hold water, and even all my plant saucers, rain barrels and I "anchor" a chunk of dunk in the storm drains out on the street as well. (tie a rock to it so it won't flow away downstream)
If you treat the standing water, the mosquito population will drop drastically and very quickly too. The dunks are non-toxic to animals and birds, as I can attest since my cat has been drinking out of the plant saucers for 15 years now with no apparent ill effects.
Here's the card - I use about 2 dunks a month, broken up into fairly small chunks. So this card costs about $10 at Home Depot or Lowe's and lasts me 3 months.
