  • The scent isn’t overpowering.

Some frequently asked questions-

  • Why are there flies on my dogs?

A fly may be drawn to a dog’s coat for a variety of reasons. This includes everything from excrement that has been matted in her fur to open sores hidden by her hair.

Some flies are even more devious than the rest. Horseflies, for instance, will bite your dog, and you, too, so be careful. Because these bites can bleed and become infected, it’s critical to treat them as quickly as possible and prevent them from happening again.

  • Are Files Harmful?

Yes, they can be. Some bite into your dog’s flesh, producing wounds that can quickly become infected, as mentioned above.

Others spread sickness – as many as 65 diseases have been identified. These might range from minor annoyances to life-threatening illnesses such as dysentery.

Although it’s unlikely that a dog will contract a potentially fatal disease due to contact with flies, there’s no reason to take the chance.

  • How to keep flies in control

While the repellents on this list do an excellent job of keeping bugs away from your dog, they can only do so much if there are swarms of flies buzzing around all the time. As a result, it’s critical to maintain the immediate vicinity as clean as possible. This includes scooping up poop as quickly as possible, tightly sealing any rubbish bins, and removing any standing water. Also, as gruesome as it may seem, a dead animal in the region might attract many flies. In that situation, removing the carcass as quickly as possible is critical (and you may need to call animal control to do this). Flytraps, strips, and zappers can be placed around your home to try to catch the pests before they land on your dog. However, avoid using anything that contains an attractant, as this will just exacerbate the problem. Finally, there are natural alternatives, such as introducing fly predators into your yard. For example, Spray containers non-biting wasp species feed on fly larvae; by releasing them around your house, you can eliminate an entire generation of flies without using any chemicals.
