Mayflies are aquatic insects commonly known as shadflies, fishflies, or Canadian soldiers in certain regions of North America. Globally, there are over 3,000 species of mayflies, primarily found in streams or other moist environments. Fish are among their main predators.

Mayflies undergo hemimetabolous development, starting as eggs and progressing through nymph stages before reaching adulthood. In some species, the transformation from nymph to adult occurs underwater.

The presence of mayflies in a river or stream generally indicates a healthy ecosystem. However, their arrival in swarms during favorable weather conditions can be quite bothersome.

It’s important to note that mayflies do not pose any harm to humans. Nevertheless, there are measures one can take to minimize inconveniences caused by mayflies.

Adult midges are often seen flying in swarms or resting on various surfaces, such as fences, walls, and protected areas like porches and entryways.

Non-biting midges are small flies resembling mosquitoes. Although they do not pose any health threats, they can be a significant nuisance, especially in communities near large bodies of water. Adult midges have short lifespans and are weak flyers.

During their peak emergence, massive swarms of non-biting midges can cover houses, vehicles, and other structures.

To discourage the congregations of these insects, it is advised to move lights away from doorways, windows, patios, and similar areas.

Replacing mercury vapor lights with yellow or sodium vapor lights can also help reduce the presence of these insects. While blacklight traps (bug zappers) can kill midges, they often attract more midges to the area than they eliminate.
