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.

In the below section we break down each of our product recommendations in a little more detail.​

The GLOUE Bug Zapper is a small, compact electronic gnat killer which works on other flying insects.

It can be placed inside or outside and is an environmentally friendly alternative to some products because it uses no pesticides or sticky glues. The GLOUE needs to be placed in an electronic outlet but is guaranteed to work 24 hours a day and 365 days a year.

The produce was designed to capture aphids, leaf miner, fungus gnats, thrips, white flies, black flies, midges, mosquitoes and other flying insects. I recommend this product to people who want a disposable but environmentally friendly alternative to more expensive electronic zappers.

These traps also feature a strong adhesive on both sides of the sheets to capture gnats and are effective on other pests, including whiteflies, blackflies, midges, and fruit flies. The sheets are UV resistant and waterproof, so individuals can water their plants without damaging the trap. I would recommend this product to people who want an inexpensive trap that can be used around houseplants.

Besides gnats, the product is also effective at catching whiteflies, blackflies, thrips, fruit flies, and midges. Safer Brand makes each stake attractive to gnats because of the glue's smell, and does not use any pesticides. I recommend this product to individuals who have houseplants and gnats that like to live around them.

This device is designed to trap and kill gnats and other flying pests. The trap can be placed or hung around the interior of your home. It has a mash outer casing that provides a safety barrier to children and pets

We suggest it should still be hung out of the way, but is safe nonetheless. It uses several ultraviolet bulbs to lure gnats to the electrified metal and manages to eliminate pests without using any chemicals or pesticides.

I would recommend the Aspectek Bug Zapper to people who would prefer to invest more initially to have a long-lasting gnat elimination trap. I also suggest that people with children invest in the trap so they know their kids won't injure themselves.


  • Most people only need to buy the insect zapper once every few years
  • Is safe to have around children and pets
  • Does not use any chemicals to kill gnats
  • Can be hung anywhere inside or outside of a home


  • Is more expensive than other traps because it is electronic

People suffering from gnat problems can use any of these products to eliminate the nuisance safely and effectively.

Out of the above options, my most recommended product is the Aspectek 20W Electric Bug Zapper. Although it is more expensive than the others, it:

  • Is long-lasting and doesn't need to be replaced often
  • Does not use any pesticides or chemicals
  • Is safe to have around children and pets
