What Is a Gnat Trap?

Loosely defined, a gnat trap is any mechanism designed to catch gnats. Gnats are small, flying, non-biting insects that often invade homes during the spring and summer. Gnats remain attracted to fruit and houseplants, and often find their way inside through windows. Gnat traps can be placed throughout your home to catch them before they reproduce or cause problems for you and your family. They typically come in two types: Physical traps and electronic zappers. 

Physical Gnat Trap

Physical traps are the cheapest option for people interested in catching gnats. Physical traps look like sheets of yellow paper.

The traps are placed in locations where gnats typically roam, including the kitchen or near potted plants. When the gnats get too close, they will fly into the paper and become stuck to the glue which coats one or both sides. Most physical traps can be bought in packs with multiple sheets, but they are not reusable.

Electronic Gnat Zapper

Electronic zappers trap and kill gnats and other flying pests using electricity.

They can be placed outdoors on patios and decks, or you can place one inside to catch gnats around your house. Electronic zappers lure gnats to them using fluorescent, often ultraviolet, lights.

The pests will fly towards the light and be shocked by several volts of electricity, killing them quickly. Unlike physical traps, zappers are reusable and need to be cleaned out after use.

Why Not Use Both?

If you have a large gnat problem, it would be prudent to combine several traps together.

Physical traps are useful to have around plants, while electronic zappers work around doors and other entrances to the house.

If you don't think you can handle the problem on your own, contacting a professional pest management company might be the way to go.

How Much Do A Gnat Traps Cost?

Gnat traps come in a variety of types and prices. The typical range is anywhere from $8-$60, with a wide assortment available for you to choose from. The main factor that determines cost is what kind of trap in which you want to invest your money.

What Type of Trap Should You Get?

At the end of the day, the price of a trap is determined by what kind you want.

Disposal paper traps are cheaper and more affordable, but often only have a single use. In many cases, you can buy a pack of ten or twelve sticky paper traps to place around your house. However, once you run out, you need to purchase more.

If you buy an electric trap, you'll need to pay more during the initial visit, but you won't need to repurchase them.

So it all depends on how much you want to initially invest. Perhaps for a smaler infestation, a physical trap might be the way to go, but then investing in an electrical trap if you have ongoing issues.

One of the most popular methods of gnat removal is to try using apple cider vinegar. This method can be hit or miss. We found the below video breaking down this method a bit more. Worth a quick watch.

What Attracts Gnats to Traps?

You might be thinking, "Why would gnats fly near the traps?" It seems like common sense to avoid them, but gnats are incapable of determining that the traps are dangerous for them.

In some cases, they actually view aspects of the traps as attractive and will approach of their own volition!

why gnats attracted to traps

Below are the two main reasons why. 

The Lights and Smells Attract Them!

Professionals designed electronic zappers to emit fluorescent light, frequently ultraviolet light. Gnats see these lights, but they aren't actually attracted to them.

Instead, the wavelength frequencies of the lights disorient bugs. Disoriented bugs have a harder time telling where they are flying, so they accidentally hit the zapper and are electrocuted. The smells in physical traps are genuinely appealing to pests like gnats, causing them to fly towards the paper because it smells good.

If your traps don't have a smell, then they will be placed in attractive locations. The gnats will then accidentally fly into the paper and become trapped.
