Low-Cost, Homemade Mosquito Trap

You can make this homemade mosquito trap from simple ingredients and materials to help control the mosquito population around your home.


| June/July 2012


Modern technology has brought us many benefits, including mosquito traps that cost hundreds of dollars, but sometimes we overlook simple solutions to difficult challenges such as mosquito control. When it comes to controlling pests, research tends to focus on chemicals or concepts that can be patented. Unless someone can make a profit from an idea, the public may never become aware of it.

Such could be the case with the simple, homemade mosquito trap developed with funding from the Bill & Melinda Gates Foundation. Tests in Israel and Africa have found that simple traps baited with fermented fruit juice and a toxin can be highly effective in reducing mosquito levels. Mosquitoes are attracted to the scent from the fruit juice because they feed on nectar and other sugar sources.

The researchers point out that the DIY mosquito trap they tested “may be suitable for the control of subterranean mosquito populations ... suitable areas may include underground storm drains systems ... with stable microclimatic conditions...”

The Israeli researchers tested their traps in cisterns. Most of us don’t have cisterns, but around our homes mosquitoes tend to seek similar locations as resting sites. Buckets, trash cans, old tires and other sheltered sites containing water often harbor mosquitoes. Why not create such sites and then place the baited traps in them? (To be sure mosquitoes can’t breed in the sites, you can add some Bt “mosquito dunks” to the water, to kill any larvae that might hatch.)

We suggest using a covered trash can or wastebasket, with some holes for the mosquitoes to enter and exit and some water in the bottom of the can, and then placing the traps inside these “mosquito shelters.” In the studies in Israel traps placed in cisterns reduced mosquito numbers by 20 times!

Here are excerpts from the researchers’ description of their bait and traps, from their paper, “Efficacy of toxic sugar baits against adult cistern-dwelling Anopheles claviger”:

Use this but when you do make the holes smaller so that no other bugs go into it besides mosquito.

Try using dry ice in a small mesh netted trap similar to a crab or crayfish trap. Some researchers use this method. Hang the trap in a barn, tree, or chicken coop. The CO2 off-gassing attracts the mosquitoes and they cannot figure a way back out. No poison or rotted fruit needed. You could make your own by using tent window netting from a fabric store stretched around some frame such as coat hangers. You can purchase dry ice at most grocery stores. You will need to replenish the dry ice regularly though but a quarter pound piece should last long enough for one night possibly less if you have cool temperatures.

We have a bumper crop of mosquitoes this year in Michigan! My only concern with this idea is that as I have honey bees, I'm wondering if this would a fatal mistake for the bees to leave something containing Spinosad insecticide. I really don't want to harm any bees.....
