This little device is cheap to create, and has been used by the US military on bases in malarial zones with fantastic results. There are many types of Ovitraps you can create, some are easier than others but require poison that is not readily available to a lot of people (like in Canada). This one does not require poison and works to effectively kill off the next generation of mosquito before they can bite you. According to some reports, after 6 weeks use this is as much as 98% effective!

I built each one of my traps for about .40 cents.

HOW DOES IT WORK?

This trap IS like honey to mosquitoes. Avoiding the sweet smell of this natural trap is like asking a teen aged boy to not look at the hot girl in class, or a child to not eat a candy. Mosquitoes look everywhere for stagnant water with a moist dark area around it to lay their eggs. They do this in at least 10 different places in their short lifespan to increase the odds of their eggs hatching. The entire reason mosquitoes exist is to suck your blood and then turn that blood into eggs. Think how hard they try to bite you... once they're full of your blood they try even harder than that to find stagnant water.

Mosquitoes can't help but lay eggs on the moist black sock on the rim of this trap. Once those eggs hatch, their tiny larvae will crawl through the screen into the stagnant water below and eventually hatch into live mosquitoes that are just too big to get back through that screen. You won't notice anything in the trap for a while as this process takes a week or two to start. So keep the traps filled with water. After 6 weeks you should see that the trap has dead bodies under the screen. That means the mosquito genocide has begun.

From what I've read, you need 4-6 of these ovitraps per acre of property. Less for urban areas, more for rural ones. Once you see your traps are full, just pull the screen out, empty the dead bodies, then refill with stagnant water. They can be used indefinitely.
