The Midge (Chironomidae (various)) is gray to green; mosquito-like but without biting mouthparts and typically measures 1/16–¼ inch. Non-biting midges (family Chironomidae) are small, delicate flies that closely resemble mosquitoes but lack the piercing mouthparts and do not bite. They are among the most abundant insects near water.

The Midge is generally low-risk, but caution is still advised. No medical risk. Do not bite or transmit disease. Nuisance pest due to sheer numbers near water. Can trigger allergic reactions in sensitive individuals from shed exoskeletons.

In Arizona, midges are most often encountered in the following situations: Dense swarms of mosquito-like insects near water at dusk and dawn. Insects coating exterior walls, lights, and vehicles. Clogged window screens and air conditioning filters. Reddish larvae (bloodworms) in water or sediment.

The Midge is most active during: Year-round near water; peak spring and fall emergence events. Arizona's warm desert climate can extend activity periods compared to other states, so year-round vigilance is recommended in the Phoenix metro and surrounding areas.

Reduce exterior lighting near water or switch to yellow/sodium-vapor bulbs. Install tight-fitting screens. Seal gaps around doors and windows. Air conditioning filter maintenance near water bodies.

No practical control for outdoor swarms near water bodies. Interior exclusion and light management are the primary strategies. Larvicide treatments in standing water features on private property.

Most fly species are drawn to food sources, moisture, organic waste, and breeding sites. For Midges specifically: Dense swarms of mosquito-like insects near water at dusk and dawn. Insects coating exterior walls, lights, and vehicles. Clogged window screens and air conditioning filters. Reddish larvae (bloodworms. Eliminating attractants is the first step — Pest Control Bros can identify the source and recommend targeted control.
