Summer is the season for outdoor activities, but it’s also prime time for pesky insects like deer flies.

If you’ve been considering buying a bug zapper to tackle the issue, you might be wondering: Do bug zappers attract deer flies?

In this post, we’ll dive deep into this question, backed by science and practical experience.

What Are Deer Flies?

Deer flies are blood-sucking insects that can be quite a nuisance, especially during warmer months.

They’re often mistaken for common houseflies but are usually more aggressive and can deliver painful bites.

They thrive in wetlands, meadows, and wooded areas, making them a common problem for those who love spending time outdoors.

The Popularity of Bug Zappers

Bug zappers have long been a popular choice for dealing with various flying insects.

These devices use ultraviolet light to attract bugs and an electric grid to zap them.

While they’re generally effective for many types of insects, their efficacy against deer flies is a topic of debate.

Do Bug Zappers Attract Deer Flies?

So, the million-dollar question: do bug zappers work on deer flies?

The answer is both yes and no.

Research shows that deer flies are primarily attracted to carbon dioxide and warmth, rather than light. In a study involving different bug-control devices, bug zappers killed fewer deer flies compared to traps that used carbon dioxide as an attractant.

Practical Experience

Anecdotal evidence seems to align with scientific studies. Many users have noted that their bug zappers are not very effective at attracting and killing deer flies.
