What time of day are horse flies most active?

Answered by Willie Powers

Well, from my personal experiences living in an area with horse flies, I can tell you that they are most active during the day. These pesky flies seem to come out in full force when the sun is shining and the temperatures are warmer.

One thing I’ve noticed is that horse flies are attracted to movement. Whenever I’m outside and moving around, whether it’s walking, running, or even just waving my arms, I seem to attract more of these flies. It’s like they’re drawn to any kind of motion.

Another factor that seems to attract horse flies is shiny surfaces. I’ve noticed that they often hover around objects that have a reflective or glossy surface, such as car windows or even sunglasses. It’s almost as if they mistake these surfaces for bodies of water, which they are known to breed near.

Carbon dioxide is another thing that horse flies are attracted to. Like many other insects, they are able to detect the carbon dioxide that we exhale when we breathe. This is why they tend to hover around our faces and can be quite annoying when we’re trying to enjoy outdoor activities.

Lastly, horse flies seem to be attracted to warmth. They are more active during the warmer months of the year and tend to be more prevalent on hot, sunny days. I’ve noticed that they are particularly bothersome in areas where the sun is directly hitting, such as open fields or near bodies of water.

Horse flies and deer flies are most active during the day when there is movement, shiny surfaces, carbon dioxide, and warmth. These factors seem to attract them and make them more active and persistent. So, if you’re trying to avoid these annoying insects, it’s best to take precautions and be aware of their preferences during the day.
