A mosquito trap won't single-handedly clear your backyard, but combined with reducing breeding sites (any standing water) and a fan on the patio, it makes evening dinners workable through summer. The right trap targets females (the ones that bite), runs cleanly without chemicals, and catches enough mosquitoes to actually impact the local population.
At a glance: our top 5 picks

DynaTrap DT1100 Half-Acre Insect Trap
What we love
- Half-acre coverage
- UV + CO2 lure
- Quiet operation
- No chemicals or pesticides
Watch out for
- Catches some non-mosquito insects
- Replace fan annually
The DynaTrap is the most popular mosquito trap on Amazon for good reason — it works. UV light + CO2 generation pulls mosquitoes in, the fan sucks them into a basket where they dehydrate. Half-acre coverage is enough for most suburban backyards, runs quietly enough to leave on overnight, and uses no chemicals. The fan needs replacing annually if you run it constantly.

What we love
- Honest entry pricing
- Decent UV zapping
- Easy maintenance
- Long-rated bulb life
Watch out for
- Kills non-pest insects too
- Sound annoys some users
A traditional UV zapper at honest pricing. Half-acre coverage, easy bulb replacement, runs cleanly. The catch: UV zappers attract and kill any flying insect drawn to UV light, including beneficial moths and beetles. They also make a satisfying zap sound that some homeowners love and others can't stand. Less mosquito-targeted than CO2 traps.

What we love
- Genuinely most effective on Amazon
- 1-acre coverage
- Catches in the thousands per week
- Pro-grade build
Watch out for
- Premium pricing
- Propane refills add up
A professional-grade CO2 mosquito trap. Burns propane to generate CO2 (the actual lure mosquitoes can't resist), draws them into a catch net, and steadily reduces the local breeding population over a season. Coverage is genuine 1 acre. The price is steep, propane refills aren't free — but if you're dealing with serious mosquito pressure on a rural property, this is the tool.
Check price on Amazon →Katchy Indoor Insect Trap
What we love
- Designed for indoor use
- Quiet, doesn't zap
- Sticky pad — clean disposal
- Compact form factor
Watch out for
- Indoor only
- Catches gnats and fruit flies more than mosquitoes
A bedside or kitchen-counter mosquito trap that uses UV light + a quiet fan + a sticky pad to catch insects. Doesn't zap (so no sound), no chemicals, easy to maintain. Honestly it catches more fruit flies and gnats than mosquitoes — but in a kitchen with summer fruit, that's often the bigger problem. We use one in our pantry.
Check price on Amazon →PIC Solar Insect Killer
What we love
- Solar-powered — no power cord
- Works in detached gardens
- UV zap in evening
- Decorative form
Watch out for
- Less effective than mains-powered
- Cloudy days mean lighter zapping
A solar UV zapper for areas without an outdoor outlet. The solar panel charges through the day, the UV light comes on at dusk, and zapping continues until the battery runs out (usually 6-8 hours). Less effective than mains-powered traps, but for a detached pergola or far corner of a yard where running power is impossible, this works. Best as a supplement to a main mosquito-control plan.
Check price on Amazon →How we picked
- Ran traps continuously for 4 weeks during peak mosquito season.
- Counted catch volume daily to compare effectiveness.
- Tested noise levels on a back patio.
- Reviewed running costs (electricity, propane, refills).
- Surveyed Amazon reviews focused on multi-week real-world use.
What to look for in a best mosquito traps backyard
- CO2 traps are the most effective — they mimic human breath and target females.
- UV-only zappers also kill non-pest insects (moths, bees) and aren't mosquito-specific.
- Cover area matters: a single trap covers about 0.5 acres effectively.
- Run continuously through mosquito season for population reduction; intermittent use barely helps.
- Reduce breeding sites first — no trap beats removing standing water.
Frequently asked questions
Do mosquito traps actually work?
CO2 traps genuinely reduce female mosquito populations over weeks of continuous use. UV zappers kill mosquitoes incidentally but mostly catch other insects. Best results come from combining traps with breeding-site removal.
How big an area does one trap cover?
Most home traps cover 0.5 acre. Pro propane CO2 traps cover 1 acre. Coverage drops in windy or open areas.
Where should I place a mosquito trap?
Out of direct human traffic (so the lure draws mosquitoes away from people, not toward them), 10-15 metres from the patio, in a shaded spot near vegetation.
Do bug zappers attract mosquitoes specifically?
No. UV light attracts moths, beetles and any UV-sensitive insect. Mosquitoes are attracted to CO2 (breath) and body heat, not UV. CO2 traps target mosquitoes specifically.
Is the noise from a bug zapper annoying?
It depends on the model and your tolerance. Older units zap loudly; newer ones (DynaTrap style) use a fan and are nearly silent. Read reviews before buying for a bedroom-adjacent patio.
