When I took the zapper home, I removed the bulb to clean the metal grid and I did saw lots of mosquitos dead on it.
Fogger idea is great but what to do indoors for those that moved inside the house.
Anecdotal evidence. I worked closely with our County Mosquito Control Manager. I would often fill in for him when he was out of work. I would sometimes operate the ULV trucks, tend traps, apply larvicides to standing water and do counts. Zappers only work on those flying by. They are not attracted to the light.
The best thing that you can do is to survey areas around your house for standing water and pour it out.
Do you have junk tires laying around? Get rid of them. Anything that holds water can be a breeding ground for mosquitoes. Do your neighbors have junk laying around? That can be a source. Unattended bird baths is another source.
Some species of mosquitoes are active all day. The majority are active at dawn and dusk. Use DEET based repellents and wear long sleeve shirts and long pants during the high bite time. Mosquitoes hide out during the day. They like shady areas like shrubs, bushes, barns and storage areas. These hiding places can be treated with Malathion.
For those moving indoors: you have to kill them one at a time. Keep the doors closed. Make sure all of your screens are in good condition.
You can buy mosquito doughnuts at your local farm store. These are put in standing water to kill the larvae. An old trick is to put some mineral oil or baby oil in large areas of standing water. This creates a film on the water surface that prevents the larvae from getting air.
