Sorting fact from folklore
Few pests attract as many myths as mosquitoes. Some are harmless, but others waste money or give people a false sense of protection. Here are the common ones, with the short verdict and a link to the full, sourced explanation.
Gadgets and products
- Bug zappers kill mosquitoes. Mostly false. Zappers kill huge numbers of insects, but studies show biting mosquitoes are a tiny fraction, and many of the dead are harmless or beneficial. Do bug zappers work?
- Ultrasonic repellers and phone apps keep mosquitoes away. No good evidence they work; regulators have acted against such claims. Choosing a repellent
- Automatic misting systems are a smart fix. Scientists and mosquito-control groups generally advise against them. Automatic misting systems
Plants and nature
- Citronella and other plants repel mosquitoes just by growing. Largely a myth; the plant sitting in your yard does little. Mosquito-repelling plants: myth vs reality
- Bats, purple martins, and dragonflies will control the mosquitoes around my home. They eat mosquitoes but do not meaningfully control them. Do dragonflies, bats, and purple martins control mosquitoes?
You and your body
- Certain blood types or foods make you a mosquito magnet. The evidence is weak and inconsistent; skin odor, carbon dioxide, and heat matter far more. Do blood type and diet attract mosquitoes?
- Mosquitoes are drawn to light like moths. Not really; they hunt by breath, heat, and scent. Are mosquitoes attracted to light?
Bites and biology
- Mosquitoes die after they bite. No, a female survives and bites again. Do mosquitoes die after biting?
- That mysterious skin sore must be a spider bite. Usually not; most suspected spider bites turn out to be something else. Mosquito bite vs spider bite
The takeaway
The things that actually work are unglamorous: remove standing water, use an EPA-registered repellent, and keep mosquitoes out with screens. See Mosquito control: what works, what wastes money.
