Many insects play an important role in controlling mosquito populations by hunting and eating them. These natural predators help reduce the number of mosquitoes in an area, which can be beneficial for both humans and ecosystems. They target mosquitoes at different stages of their life cycle, from larvae in water to adults flying in the air.
Dragonflies and damselflies are among the most effective mosquito hunters. As adults, they catch mosquitoes mid-air with impressive speed and precision. Even in their immature stage, when they live in water, they feed on mosquito larvae, making them valuable predators throughout their entire life cycle.
Some aquatic insects specialize in hunting mosquito larvae. Water striders, backswimmers, and diving beetles patrol ponds, puddles, and slow-moving water where mosquitoes breed. These insects detect movement on the water’s surface or below it, quickly capturing and feeding on developing mosquitoes before they can mature.
There are also surprising predators like certain mosquito larvae that feed on other mosquito larvae. These predatory species help limit overcrowding and competition in breeding sites. Additionally, insects such as ants and beetles may feed on mosquito eggs or larvae when they encounter them in damp environments.
Spiders, while not insects, also contribute to mosquito control by trapping adult mosquitoes in their webs. Flying insects that get caught in sticky silk strands are quickly immobilized and consumed. This adds another layer of natural control, especially in gardens and around homes.
Together, these predators form a natural defense system against mosquitoes. By maintaining healthy habitats—like clean water sources and plant diversity—people can encourage these helpful species to thrive. Even though they often go unnoticed, these small hunters play a big role in keeping mosquito populations in check.
Insects That Eat Mosquitoes
Dragonfly (Anax junius)
The Common Green Darner Dragonfly is arguably the most effective mosquito predator on the planet, earning it the well-deserved nickname “mosquito hawk.” It is a supremely accomplished aerial hunter with a documented hunting success rate of over 95% — the highest of any predatory animal on Earth.
Its enormous compound eyes provide nearly 360-degree vision, allowing it to track and intercept mosquitoes in flight with extraordinary precision. Both the aquatic larval stage — called a nymph — and the adult dragonfly are dedicated mosquito consumers, making this species a double-threat predator across two life stages and two distinct environments.
Damselfly (Ischnura elegans)
The Blue-Tailed Damselfly is a close relative of the dragonfly and shares its predatory lifestyle, though it is a somewhat more delicate and slower hunter. Like dragonflies, damselfly nymphs are voracious aquatic predators that consume mosquito larvae in ponds, streams, and standing water.
Adult damselflies hunt small flying insects including mosquitoes, using their basket-like arrangement of spiny legs to scoop prey out of the air during flight. They tend to hunt at lower heights and in more vegetated environments than dragonflies, covering a slightly different ecological niche in mosquito control.
Predatory Stonefly (Perla bipunctata)
The predatory stonefly nymph is a highly effective underwater mosquito larva hunter found in clean, fast-flowing streams and rivers across Europe and North America. Stonefly nymphs are long-lived aquatic predators — spending up to three years in the larval stage — and consume enormous quantities of mosquito larvae, midge larvae, and other small aquatic invertebrates throughout their development.
Their presence in a waterway is considered a strong indicator of water quality, as they are highly sensitive to pollution. Adult stoneflies are short-lived and do not feed, making the nymph stage entirely responsible for the species’ predatory impact.
Backswimmer (Notonecta glauca)
The Common Backswimmer is a fascinating aquatic insect that swims upside down just beneath the water surface, using its long, oar-like hind legs to propel itself through the water with considerable speed. It is a fierce and aggressive predator of mosquito larvae and pupae, seizing prey with its forelegs and delivering a paralyzing bite through its piercing beak before consuming the contents.
Despite being only about 15mm long, it will attack prey significantly larger than itself, including small tadpoles and fish fry. Its presence in garden ponds and still water bodies makes it an extremely valuable natural mosquito control agent.
Water Boatman (Corixa punctata)
While most Water Boatman species are primarily algae and detritus feeders, several predatory members of the family Corixidae actively hunt and consume mosquito larvae in shallow freshwater environments. They are fast, agile swimmers that use their flattened, paddle-like legs to navigate through aquatic vegetation in search of prey.
They breathe by trapping an air bubble beneath their wings, allowing them to remain submerged for extended periods while hunting. Their presence in garden ponds, ditches, and slow-moving water provides a passive but continuous level of mosquito larval control throughout the warmer months.
Diving Beetle (Dytiscus marginalis)
The Great Diving Beetle is one of the most formidable aquatic predators in freshwater ecosystems, and mosquito larvae are among its most frequently consumed prey items.
Both adults and larvae are aggressive hunters — the larvae are particularly ferocious, possessing large, hollow, sickle-shaped mandibles through which they inject digestive enzymes into prey before sucking out the liquefied contents. A single diving beetle larva can consume dozens of mosquito larvae in a single day. Adults carry a supply of air beneath their wing cases, enabling extended underwater hunting sessions before surfacing to replenish.
Robber Fly (Asilidae)
Robber Flies are among the most accomplished aerial predators in the insect world, and adult mosquitoes form a regular part of the diet of many species in this diverse family. They are stocky, bristly flies with powerful legs and excellent binocular vision that allows them to spot and intercept flying prey with remarkable accuracy.
A Robber Fly typically perches on an elevated vantage point, launches into a high-speed pursuit when prey is detected, and seizes it in mid-air before returning to its perch to feed. Their saliva contains neurotoxic and proteolytic compounds that rapidly immobilize and begin digesting captured mosquitoes.
Predatory Midge (Corethrella species)
Predatory midges of the genus Corethrella are small but highly specialized mosquito hunters that use an extraordinary and somewhat sinister hunting strategy — they eavesdrop on the mating calls of male frogs to locate the same standing water bodies that female mosquitoes prefer for egg-laying.
Once at the water source, adult female predatory midges hunt and feed on other small flying insects including mosquitoes. Their larvae are also aquatic predators of mosquito larvae. They represent one of the most ecologically specialized members of the mosquito-eating guild and are an important, if rarely celebrated, component of natural mosquito population regulation.
Lacewing Larva (Chrysoperla carnea)
The Common Green Lacewing is best known as a garden pest controller due to its voracious larval appetite for aphids, but lacewing larvae are in fact generalist predators that consume a wide range of small soft-bodied insects including mosquito larvae in moist leaf litter and damp soil environments.
They are equipped with prominent, hollow mandibles through which they inject digestive fluids into prey before sucking them dry — earning them the nickname “aphid lions.” Adult lacewings feed primarily on nectar and pollen but are also known to consume small resting insects including adult mosquitoes when the opportunity arises.
Yellowjacket (Vespula maculifrons)
The Eastern Yellowjacket is a surprisingly effective mosquito predator, particularly in suburban and semi-rural environments where both species are abundant. Worker yellowjackets hunt a wide variety of soft-bodied insects to provide protein for colony larvae, and adult mosquitoes — slow-moving, protein-rich, and abundant — are frequently targeted.
Workers catch mosquitoes resting on vegetation, rapidly sting and immobilize them, and chew the body into a protein ball that is carried back to the nest and fed to developing larvae. While yellowjackets are primarily associated with bee predation and food scavenging, their broader predatory role in pest control is frequently underestimated.
Spined Soldier Bug (Podisus maculiventris)
The Spined Soldier Bug is a predatory stink bug found across North America that is highly valued in biological pest control programs for its broad appetite for pest insects. While primarily associated with preying on caterpillars and beetle larvae, it has been documented feeding on adult mosquitoes and other small flies when they are encountered on vegetation.
It uses its piercing rostrum to inject saliva that both immobilizes prey and begins the digestive process before it feeds. Its presence in gardens and agricultural landscapes provides a passive but meaningful contribution to mosquito population suppression alongside its better-documented role as a caterpillar predator.
Firefly Larva (Photinus pyralis)
The Common Eastern Firefly, celebrated worldwide for the magical bioluminescent displays of its adults, has a larval stage that is an active and effective soil-dwelling predator — and mosquito larvae inhabiting moist soil and shallow water edges are among its documented prey items.
Firefly larvae live in damp soil, leaf litter, and the margins of ponds and streams, hunting small invertebrates using the same hollow, venom-injecting mandibles seen in other beetle larvae. They are entirely nocturnal and spend one to two years as underground predators before pupating. Maintaining healthy firefly populations in gardens is therefore a doubly rewarding mosquito control strategy.
