Gnats—a broad term that includes fungus gnats, fruit flies, midges, drain flies, and small house flies—are tiny flying pests that tend to congregate in large numbers. Although mostly harmless, gnats can be extremely hard to get rid of once they’re attracted to your home. If you’re ready to bring in a pro, this guide will help you plan your budget.

Gnat Exterminator Cost Factors

These are the main factors that will impact the cost of a gnat extermination.

Type of Treatment

Your gnat exterminator may offer different treatments at varying price points to get rid of gnats. The most common options are traps or spot treatments. To remove visible gnats, the expert may apply traps to lure and kill the pests in places where they seem to congregate. For more severe gnat infestations, they may apply chemical spot treatments to eliminate large groups of pests at a time. Then, the gnat professional will evaluate the best way to reduce or get rid of the gnat’s developmental sites to prevent future infestations.

Number of Treatments

Gnat exterminator visits cost $150 to $250 per treatment. If you need several treatments to eliminate the infestation, here’s what your budget could look like.

Number of TreatmentsAverage Total Cost
1$150–$250
2$300–$500
3$450–$750
4$600–$1,000
5$750–$1,250

Gnat Exterminator Ongoing Expenses

Here are a few ongoing expenses to consider with your gnat exterminator cost.

Ongoing Treatment

Ongoing treatments from a pest control service cost around $40 to $70 per month or $100 to $300 quarterly. If gnats continue popping up, you may want to consider routine visits from a professional insect exterminator.

DIY Prevention

After your exterminator finishes up the treatment, it’s important to keep up with routine DIY prevention. Most methods are very inexpensive and mostly require your time and dedication for maximum effectiveness, such as the apple cider vinegar or bleach methods. Be sure that you remove items that attract gnats to your home, including open food and water sources, organic materials, perfumes, and scented candles.

DIY Gnat Extermination vs. Hiring a Pro

Learning how to get rid of gnats on your own can potentially save you hundreds on treatment, but it takes dedication and often will take longer than professional treatment. Overall, DIY treatment is very inexpensive and can be done for under $20, depending on the method. For example, sticky traps cost between $6 and $15, while homemade vinegar traps cost pennies if you use recycled materials.

Still, a gnat infestation can be relentless, and if DIY treatments seem to only be a temporary fix for the situation—or if you just want them gone ASAP—hiring a local insect exterminator is the best route to take.

Cost of Common Gnat Exterminator Add-Ons

Unfortunately, one pest problem can lead to another. Since gnats are at the bottom of the insect food chain, an ongoing infestation can prompt larger pests to take up residence, too.

Tips to Reduce Your Gnat Exterminator Cost

The easiest way to save on treatments and future exterminator visits is to eliminate what attracted the gnats to your home in the first place. Here are a few tips to keep costs down:

  • Before calling an exterminator, try to identify the source of the infestation. If it's a simple problem, such as overripe fruit or damp soil, you may be able to solve it on your own.

  • Get multiple quotes from different insect exterminators to compare prices and find the best deal.

  • Regularly clean your home and remove any open sources of moisture or food.

Frequently Asked Questions

There are several possible reasons for a gnat infestation, and they vary based on the type of insect. One common reason is overwatering houseplants, which can create a moist environment that is attractive to fungus gnats. Another reason is leaving fruit out on the counter for too long, which can attract fruit flies. Drain flies are typically attracted by standing water and bacteria that are often the result of buildup or a clog in your drain or sewer line.
