You put up a hummingbird feeder. A tiny bird arrives, hovers for a few seconds, then disappears into the yard.
Meanwhile, mosquitoes are waiting for you near the patio.
It raises an appealing question: Could hummingbirds reduce mosquitoes enough to actually make a difference around your home?
The idea isn’t as ridiculous as it might sound. Hummingbirds don’t live on nectar alone. They also hunt tiny insects and spiders, which provide nutrients that sugar-rich nectar doesn’t.
And yes, mosquitoes can be on the menu.
But evidence that hummingbirds reduce mosquitoes enough to provide meaningful backyard mosquito control is much harder to find. We went looking for evidence of the second claim.
Here’s what we found.
Hummingbirds Aren’t Vegetarians
The feeder outside your window can give the wrong impression. Hummingbirds are famous for drinking nectar, but they’re also insect hunters.
The Smithsonian National Zoo says ruby-throated hummingbirds prey on tiny insects when they’re available. Penn State Extension goes a step further, noting that ruby-throated hummingbirds may capture some mosquitoes hiding in shady daytime resting places, including insects gathered to feed their nestlings.

Pollinator-Friendly Mosquito Control
So the first part of the claim checks out: Hummingbirds eat insects, and mosquitoes can be among them.
The more interesting question is what happens next.
Eating Mosquitoes Isn’t the Same as Controlling Mosquitoes
Imagine watching a hummingbird catch several mosquitoes around your garden. It’s tempting to conclude that you’ve recruited a miniature mosquito-control crew.
But to actually reduce a mosquito population, hummingbirds would have to consume enough mosquitoes, often enough, in the right places, to noticeably change how many are present. That’s a much higher bar.
In reviewing current mosquito-control guidance, PestMarket did not find strong evidence showing that simply attracting hummingbirds to a residential yard produces a meaningful reduction in mosquito populations. That’s why we’re grading the claim Limited Evidence, rather than Proven.
The distinction matters.
Can a hummingbird eat mosquitoes? Yes.
Can hummingbirds contribute to the natural predator community in your yard? Yes.
Will putting up a hummingbird feeder noticeably solve your mosquito problem? There’s not good evidence to promise that.
And mosquito biology helps explain why.
Your Yard Can Produce Mosquitoes Faster Than Birds Can Find Them
The real battle against mosquitoes often happens before they can fly.
Mosquito eggs and larvae develop around water, and some species need astonishingly little of it. The EPA says mosquito breeding sites can include buckets, toys, plant saucers, old tires and even something as small as a bottle cap.
EPA:
General Information About Mosquitoes
University of Maryland Extension says mosquitoes can breed in as little as one teaspoon of water and, under suitable conditions, can develop from egg to adult in as little as four days.

Controlling Mosquitoes
That’s the problem with relying on predators alone. While a hummingbird is chasing individual flying insects, mosquito larvae could be developing unnoticed in a clogged gutter, forgotten flowerpot saucer or children’s toy.
Removing that breeding habitat attacks the problem at its source.
What About Putting Up More Hummingbird Feeders?
If hummingbirds eat insects, perhaps attracting more hummingbirds should mean fewer mosquitoes. It’s a reasonable hypothesis.
But a feeder is primarily giving hummingbirds sugar water, not directing them to hunt mosquitoes. And we couldn’t find strong evidence showing that adding hummingbird feeders creates enough additional mosquito predation to function as reliable mosquito control.
That doesn’t mean you shouldn’t have hummingbird feeders. If you enjoy hummingbirds, that’s a perfectly good reason to put one up.
Just don’t think of the feeder as a mosquito trap with wings.
There’s an Ironic Mosquito Problem to Watch For
Here’s where the story gets more interesting.
People trying to attract birds often add water to their yards. Bird baths, fountains and small water features can make a yard more attractive to wildlife.
They can also become mosquito habitat if they’re neglected.
EPA mosquito-control guidance recommends emptying and changing water in bird baths, fountains and other containers at least weekly to eliminate potential mosquito habitat.
EPA:
Success in Mosquito Control: An Integrated Approach
So it’s possible to create an ironic situation: You attract birds hoping they’ll eat mosquitoes while simultaneously giving mosquitoes somewhere to reproduce.
A clean, maintained bird bath is one thing. A forgotten container of stagnant water sitting behind the garden is another.
What Actually Works Better Against Backyard Mosquitoes?
If your goal is specifically to reduce mosquitoes rather than simply create a wildlife-friendly yard, the evidence points elsewhere.
Start with water.
EPA and university mosquito-control guidance consistently emphasizes eliminating standing water around homes because mosquitoes depend on water during their immature stages.
Walk around the yard and look for places that don’t immediately scream “mosquito nursery”:
- Flowerpot saucers
- Children’s toys
- Buckets
- Clogged gutters
- Corrugated drainpipes
- Tarps
- Old tires
- Bird baths
- Trash and recycling containers
If standing water can’t reasonably be removed, Bti (Bacillus thuringiensis israelensis) is another established option for appropriate mosquito-breeding sites.
EPA says Bti targets larvae of mosquitoes, black flies and fungus gnats and has been shown to reduce mosquito larval populations. EPA also notes that residential Bti products can be used in appropriate water-holding areas such as flowerpots, tires and bird baths according to their labels.
For personal protection, EPA recommends measures including eliminating mosquito habitat, maintaining screens and using appropriate mosquito repellents.

The PestMarket Verdict
So, should you invite hummingbirds into your yard? Absolutely, if you like hummingbirds.
Plant nectar-rich flowers. Enjoy watching them hover around the garden. Give them a properly maintained feeder if you want one, and appreciate the fact that these tiny birds are also insect predators.
But don’t fire your mosquito-control strategy and replace it with hummingbirds.
Evidence Grade: LIMITED EVIDENCE
What appears supported: Hummingbirds eat small insects and may consume mosquitoes.
What isn’t well established: That attracting hummingbirds to a residential yard will reduce mosquito populations enough to provide meaningful mosquito control.
For now, a hummingbird catching a mosquito is best viewed as a nice bonus.
The bucket of standing water behind your shed is probably a much better place to focus your attention.
