Mosquitoes are drawn to fluorescent or incandescent lights, as well as dark and red clothing.
Beyond slapping: fend off the mozzies
From eNews, July 24, 2008
Mosquito numbers are up in Minnesota this year, according to the Twin Cities Metropolitan Mosquito Control District, but the bloodsuckers don't have to spoil your summer evenings. Entomologist Jeff Hahn of University of Minnesota Extension has some suggestions that may help you reduce the mosquito or mozzie (Australian slang for mosquito) problem near your home.
- Cut weeds and tall grassy areas near your home to help reduce areas that can harbor mosquitoes.
- Leave yard lights off when possible to avoid attracting the pests. You can also try less attractive lights such as sodium lights, since fluorescent or incandescent lights tend to draw mosquitoes.
- Check that window and door screens fit properly. Repair or replace any screens with holes or tears.
- Remove any containers that may hold water, such as old tires. If they can't be removed, then drain them. If this isn't possible, apply a small amount of vegetable oil on the water's surface to kill any larvae in the water.
- Keep gutters clean so water doesn't accumulate.
The Metropolitan Mosquito Control District has already treated thousands of acres of mosquito breeding sites in the Twin Cities area to keep as many larval mosquitoes as possible from developing into biting adults. (The mosquito control using ground vehicles and backpacks usually begins in mid- to late May and continues through September.) "Mosquitoes are most active early in the morning and at dusk," says Hahn. "Try to avoid going out at those times when possible. If you find yourself out when mosquitoes will be a problem, protect yourself by wearing long-sleeved shirts and long pants."
He also suggests using a repellent, and says DEET is the most effective. He says to apply DEET to clothes or skin, but only enough to lightly cover the desired areas. "Do not over-apply repellents," he cautions. "Do not treat children with a product containing more than 15 percent DEET, and always read product information thoroughly before using."
