What Is a Mayfly?

The Mayfly is a fly with an elongated body and a pair of wings. Their body appearance is quite similar to that of miniature mosquitoes.

Mayflies are aquatic insects in the same category as dragonflies and damselflies, except that the mayflies are larger. Their length is around 5.2 inches, with a set of antennae on their heads, indicating that they are neither snakes nor mosquitoes.

The mayfly family consists of thousands of species of mayflies globally, with approximately 400 genera in 42 families. Their bodies are typically yellow, black, or other dull colors, all with transparent sets of wings.

The presence of mayflies in homes, yards, or bodies of water around the house indicates that the place is unpolluted and clean. The eggs hatch in large quantities from Spring to Autumn.

The Mayfly’s Life Cycle

Since the mayflies are aquatic insects, they spend most of their lives in or around fresh water. The lifecycle of a mayfly is pretty simple. The female mayflies lay their eggs on the water surface, which sink beneath, sticking to stones and plants after.

After hatching, the nymph stays underwater, feeding on other aquatic organisms and plants. The larval and the nymph stage are the only times a mayfly eats. Thus, an adult mayfly does not have a mouth.

Once fully developed, the nymph swims to the water’s surface and sheds off its covering. Once the wings are fully dry, they can be called a fully-grown adult mayfly.

Are Mayfly Swarms Dangerous?

Since these insects do not bite, sting, or spread bacteria, they are not dangerous to humans, plants, or other animals. Unless they are swarming, they are harmless.

This means that the most significant risk associated with mayflies is when they are mating, as they gather into colossal mayfly swarms, blocking vision. For example, if you encounter a mayfly swarm while driving, you might not be able to see the road ahead. The mayfly buildup also causes slippery road conditions.

How to Get Rid of Mayflies?

If you desire to get rid of mayflies from your home and yard, the best way to do so is to get rid of the stuff that these mayflies are easily attracted to. Several things attract the mayflies, such as standing water, white light, etc.

Once the nymph grows into an adult mayfly with wings, it will immediately fly around, seeking a mate. This is because the mayflies have a short lifespan and need a mate quickly to reproduce.

The following are a few easy ways to get rid of mayflies naturally.

Get Rid of Stagnant Water

After mating, female mayflies seek stagnant water for their eggs. You should remove any standing bodies of water from your yard. If you have a pool at your house, cover it with a pool cover and use chemicals to keep them away. Also, keep the pool water clean by removing any debris from the standing water.

Turn off Any Unnecessary Lights

Mayflies are most attracted to lights. They tend to move quickly to wherever they see bright and white light. You can eliminate the mayflies by switching off unnecessary lights at night in your house and yard, or by dimming any intense lighting around your property. You can use exterior lights like shed lights, patio lights, pathway lights, porch lights, string lights, and other dim lights to prevent the mayflies from entering your home.

Install a Bug Trap

One of the best ways to trap mayflies is to install a bug zapper alongside white or yellow lights. Since light attracts mayflies swarms, they can easily get trapped in the bug zapper once they come near the trap.

Chemical Foggers

Consider using a chemical fogger if your house is located in an area with many mayflies around, like a pond or a lake. Chemical foggers are pesticides that can instantly kill all the mayflies around. However, you should first check with the laws if it is legal to use in your area and if you know how to use it properly.

Wait for Them To Die Naturally

It may sound strange, but simply waiting for the mayflies to die naturally is also a good option. Since these insects do not have a long lifespan, their wait is almost worth it. It only takes a few days for the whole mayfly infestation to die.
