How to Keep Horse Flies Away from Your Pool

Poolside barbecues, relaxing in the sun, and enjoying the warm weather with friends and family is what summer is all about. But when you’re dealing with horseflies, it can be difficult to enjoy time outside. Horseflies are known for their painful bites, and they’re common near pools.

Horseflies have been around for thousands of years and are typically found in warmer climates around the world. They’re black or dark brown in color, have large eyes, and have clear wings that lay flat over their body when at rest. They’re not just annoying pests; they can also spread disease to people and animals.

Horseflies are attracted to water because they need it to breed. So if you have a pool in your yard, there’s a good chance they’ll be a problem.

Fortunately, you don’t have to give up on your favorite outdoor activities just because horseflies are present. Read on to learn how to keep them away from your pool so you can get back to enjoying summer again.

12 Ways to Keep Horse Flies Away from Your Pool

During summertime, horse flies will be swarming everywhere. This means that it is very hard to get rid of them completely. However, there are ways in which you can control their numbers around your swimming pool. Here are some effective ways to keep horseflies away from your pool:

1-Keep Your Pool Clean

Horseflies are attracted to pools because they know that they will find water, food, and shelter.

To avoid attracting these obnoxious pests, make sure you have a good filtration system in place and clean the pool regularly with our surface skimmer or vacuum heads. Also, make sure there are no weeds growing around your pool since these can provide shelter for them.

2-Use Plants as a Natural Repellent

Horseflies don’t like certain plants more than others; they hate all plants equally! But some are more effective than others at keeping them away (and we’re not talking about poisonous plants here!) These include:

  • Citronella plants – this popular mosquito repellent actually works great to repel horseflies too!
  • Catnip – this plant is known to be 10 times more effective than DEET when it comes to repelling mosquitoes
  • Lavender – you probably know that lavender has a pleasant scent, but did you know that it also repels flies? That’s because flies, horseflies included, hate the smell.
  • Cypress, eucalyptus, and marigolds – are also excellent natural repellents.

3. Use a Deet-Based Repellent

Use insect repellent spray or lotion on yourself and your children if you’ll be lounging around the pool area for long periods of time. Use one that contains DEET or another strong active ingredient.

The best way to keep horseflies away from you while by the pool is to use a deet-based repellent. When you spray it on yourself, it will keep all insects away from you for several hours.

4. Set Up an Electric Fan Around the Pool Area

Horseflies are weak fliers and most of them cannot fly well in moving air. The electric fan will help create a breeze around the pool area that will make it more difficult for horse flies to stay airborne. The breeze will also prevent horses from landing on the water surface and biting people who are swimming in the pool.

5. Keep the Water Moving

Any type of water movement will discourage horse flies from laying eggs in your pool because it can disturb the larvae that live in the water. Install an aerator or fountain to keep the water moving, or run a motorized pool sweeper along the bottom of the pool.

6. Add Chlorine

Horsefly larvae like stagnant water with lots of organic matter in it — just like swimming pools do when they aren’t properly maintained. Keep things clean, and add enough chlorine to keep the water crystal clear and free of algae. The amount of chlorine required depends on many factors, including temperature and how often you use the pool, so follow the manufacturer’s instructions on how much to add.

7. Use Citronella Candles

Place citronella candles outside the pool area. While they won’t necessarily keep horseflies away, they’ll at least add some décor and aroma to your deck or patio area.

8. Spray Insect Repellent Near the Pool

You can use an insect repellent spray in areas where horse flies are most likely to appear. This includes wooded areas and areas that contain tall grass or bushes.

9. Wear Light Clothing When Swimming

As we mentioned above, horse flies are attracted to dark colors like black and blue — so try wearing light-colored swimwear instead!

10. Eliminate Standing Water Near the Pool

Mosquitos love standing water and if you have any in your backyard, it can attract horse flies as well as other pests like mosquitos and ticks.

11. Use a Bug Zapper

Mosquitoes and flies are attracted to light at night. Bug zappers are designed to attract mosquitoes and other insects, so place one near your pool to eliminate them before they become a nuisance. You can also use citronella candles or tiki torches around the perimeter of the pool for this purpose.

12. Keep All Food Away from the Edge of Your Pool When You’re Eating Outside

Nobody likes having flies around as they eat their lunch, especially horseflies! They will not hesitate to land on your burger bun if given half a chance. So make sure all food is covered or kept well away from the edge of your pool when you’re eating outside.

In summary, Horse flies are pesky insects that bother people and animals and can pose a threat to people and pets. These large, aggressive flies can spread diseases such as anthrax, hog cholera, swine brucellosis, and tularemia and can cause serious animal wounds.

Horseflies typically live in swampy areas and near livestock, but they can sometimes invade backyards. They are attracted to light-colored objects, especially dark clothing worn by people or animals.

If you want to keep horseflies away from your pool, use organic methods that stop the bugs from invading your pool and yard.
