What Are Midges?

Midges belong to the Chironomidae family, a group of non-biting flies commonly found near bodies of water. They are often mistaken for mosquitoes due to their similar appearance, but unlike mosquitoes, midges do not bite or transmit diseases.

While midges are sometimes called mayflies, this is actually a misnomer. Mayflies belong to a completely different insect group and are indicators of improving water quality.

Midge Biology & Life Cycle

Midges go through four life stages:

1. Egg Stage – Females lay eggs on the surface of water, which sink and hatch within days.
2. Larval Stage – Larvae live in mud or sediment, feeding on organic matter.
3. Pupal Stage – After several weeks, larvae transform into pupae before emerging as adults.
4. Adult Stage – Adults live for only a few days, swarming in large numbers near water sources.

Midges vs. Mosquitoes: Key Differences

Although midges resemble mosquitoes, they have distinct differences:

• Mosquitoes bite; midges do not.
• Mosquitoes have a proboscis for feeding on blood; midges lack this feature.
• Midges swarm more frequently than mosquitoes.
• Mosquitoes can transmit diseases; midges do not.

Are Midges Harmful?

Midges are not harmful to humans. They do not bite or spread diseases, but their swarming behavior can be frustrating. However, biting midges (a different species) can cause skin irritation and allergic reactions.

Why Are Midges Bigger Near the Lake?

If you’ve noticed that midges near Lake Erie are larger than those in Cleveland Heights, you’re not imagining things! The size of midges varies depending on environmental conditions. Those near the lake tend to be twice as large due to differences in food availability and habitat.

How to Deal With Midges

While midges are unavoidable during their peak season, here are some ways to minimize their presence:

• Keep windows closed to prevent them from entering your home.
• Use yellow or warm-colored lights, as midges are attracted to bright white lights.
• Install fine mesh screens to block their entry.
• Clean outdoor surfaces, as midges tend to gather on walls and ceilings.

Midges may be a seasonal nuisance, but they are an important part of the ecosystem, serving as food for fish and birds. If you have any questions or need assistance with pest control, Cleveland Best Pest Control is here to help!
