Banishing Mayflies: 5 Tips For A Bug Free Lake Experience

Summer is a great time to enjoy the outdoors, especially near the serene beauty of lakes or ponds in rural areas. Unfortunately, swarms of mayflies can turn your idyllic experience into a nightmare. These flying insects can swarm in vast numbers as they become a nuisance. However, they can harm horses with horse fever.

Therefore, it’s essential to learn how to get rid of these pesky flies near the lake or pond in your area. In this article, we’ll give you some tips on how to do that.

Clean Up Your Surroundings

Mayflies in New Hampshire and other New England areas as well as Pennsylvania and Florida are common. They breed in water or mud, mainly in slow-moving, clean-water streams or rivers.

However, they can also lay their eggs on the stems of aquatic plants, rocks, or other floating debris. Thus, it’s necessary to keep your premises clean and tidy.

Remove any standing water, organic matter, or garbage that can serve as a breeding ground for flies. Clear away any debris accumulated near your lake or pond around your rural home.

Use Traps 

You can use various types of traps to catch and kill them. The simplest trap is a sticky tape, which you can hang around the outside seating or relaxation areas. These also help with any cluster flies you may have as well.

For larger areas, use yellow sticky card traps, which are eco-friendly and efficient in trapping large amounts of flies. You can also use CO2 traps that emit carbon dioxide, mimicking human breath, to lure these flies in.

Use Insecticides

Insecticides are chemical compounds that can kill or repel insects. Always read the product label and follow the instructions carefully. You can use sprays, dust, or granules to kill the insects.

Always wear protective gear when applying insecticides, use them in a well-ventilated area, and keep children and pets away from the treated area.

Use Natural Repellents

You can use natural repellents such as essential oils, herbal sprays, and candles to deter flies. Lavender, peppermint, eucalyptus, lemongrass, and citronella are some of the effective essential oils. You can also plant some natural repellent plants like marigolds, basil, or chrysanthemum around your area.

Herbal sprays made from these plants can also be used to repel these types of flies. Citronella candles are also popular for their repellent properties.

Though natural repellents are not as potent as chemical insecticides, they are eco-friendly and safe for human and animal health. The repellents are great for getting rid of the flies in your home. 

However, these flies do not like the scent of garlic.

Wear Protective Clothing

Wearing clothes that cover your body can prevent these and other flies from annoying you. Wear long-sleeved shirts, long pants, socks, and hats. You can also use mosquito nets or head nets to cover exposed areas.

Wearing light-colored clothing can also help, as they are attracted to dark colors.

The Mayfly Lifecycle

The Mayfly is known for their short-lived existence as they pass through the different stages of their life cycle. These aquatic insects spend most of their lives as nymphs in freshwater streams, where they feed on algae and organic matter.

After one to three years, they make a dramatic transformation into winged adults, emerging from the water en masse in a phenomenon known as a “hatch.” Adult ones live for only one day to a few short weeks, during which they mate and lay eggs before dying.

Although their lives may be brief, these flies play a critical role in the ecosystem, serving as a vital source of food for many other species.


These nasty flies can turn your outdoor experience into an itchy and irritating encounter, but with the above tips, you can prevent them from ruining your day. Clean up your surroundings, use traps, insecticides, and natural repellents, and wear protective clothing.

Don’t let these pesky insects keep you indoors when you can enjoy the beautiful scenery of your lake or pond. Follow these tips, and enjoy your bug-free summer season.
