Dealing with a gnat infestation at work can be frustrating. Those tiny flying insects seem to appear out of nowhere, swarming around your computer monitor or hovering over your lunch. While gnats are more of a nuisance than a health hazard, they can quickly become a distraction in an office environment. Here’s a guide on identifying gnats, understanding why they may be present, and most importantly, how to get rid of gnats at the office.
What are Gnats?
“Gnat” refers to any small insect that looks like a mosquito or fly. Gnats like fruit flies and fungus gnats are most often found inside.
Fruit flies are tiny flies that are attracted to ripe or rotting fruits and vegetables They can enter an office through various means, such as
- Produce brought in by employees
- Food waste in trash cans or drains
- Spilled sodas, juices, or alcohols
Fruit flies lay eggs on fermenting foods, where the larvae can develop. A female can lay up to 500 eggs at one time, so populations multiply rapidly.
Fungus gnats like damp places where fungus grows. They can come in from the outside or through potted plants. Fungus gnat larvae eat dead plants in the soil. These gnats don’t bite people, but they can be annoying.
Why are Gnats Attracted to Offices?
There are a few reasons gnats may end up infesting an office:
- Trash cans and drains can accumulate food waste, providing ideal breeding spots for fruit flies.
- Houseplants if overwatered, allow fungus gnat larvae to thrive in the damp soil.
- Food spills such as soda, juice, alcohol, or rotting fruit are magnets for gnats.
- Props or decor like fruit bowls offer food sources for gnats.
- Poor screens on windows or doors allow easy entry for flying gnats.
Since gnats reproduce quickly, a small group of breeding flies can quickly grow into a large population. Sticky traps might catch some adults, but they don’t get rid of the problems that make gnats thrive.
How to Get Rid of Gnats in an Office
Eliminating gnat infestations requires removing their food sources and breeding grounds. Here are some tips:
Remove Trash Frequently
- Take out garbage daily, especially food waste that can rot.
- Use lined trash cans with tight fitting lids.
- Clean trash cans regularly with soapy water to remove residues.
Keep Drains Clear
- Pour boiling water down sinks weekly to kill larvae.
- Use a wire brush or plunger to loosen debris.
- Apply drain cleaner monthly to remove organic buildup.
Allow Soil to Dry Out
- Check office plants for fungus gnats before bringing indoors.
- Allow the top inch of soil to dry between waterings.
- Remove excess moisture by repotting plants in fresh, sterile soil.
Clean Up Spills Promptly
- Wipe up spilled sodas, juices, wine, etc. right away.
- Remove rotting fruit from desks and counters.
- Store employee snacks in sealed containers.
Install Fly Screens
- Ensure windows and doors have tight-fitting screens without gaps or holes.
- Keep exterior doors shut and use auto-closing devices.
Contact a Pest Control Professional
For severe gnat infestations, contact a pest control company. They can:
- Identify entry points and breeding areas.
- Apply targeted insecticide treatments.
- Provide follow-up visits to ensure elimination.
An office can stay pest-free as long as food sources and places to breed are carefully removed and screens are put up to keep out more gnats. Clean up after yourself, let the dirt dry, and keep food in containers with lids. If the problem persists, bring in professional pest control support. Those annoying gnats will be gone for good if everyone works together.
How to Prevent Gnat Infestations
Prevention of fruit flies involves three basic steps to make sure they don’t become problems inside the home:
- Use ways to keep them out, like effective screening, to keep them out.
- Throw away or store fruit and vegetables in a way that makes it unlikely that flies will get into them. Keep products in the fridge and inside sealed containers.
- Keep all trash cans, sink drains, and food containers clean so that flies don’t have places to live and eat.
When it comes to fungus gnats, avoid overwatering plants so that plant roots stay healthy and soil fungal growth is minimal.
Another important recommendation is to periodically inspect any open bags of leftover potting soil to ensure it is gnat-free.
How does a gnat infestation in the house start?
Fruit flies can enter homes through open doors and screens, or as eggs and larvae on produce. Once inside, they eat and develop in over-ripened fruits and vegetables. Other likely places for fruit flies to develop are:
- Poorly cleaned drains
- Trashcans
- Moist places containing decomposing organic matter
Fruit flies can lay up to 500 eggs at once, so they often get into things and stay there for a long time.
Fungus gnats are drawn to damp soil and usually get into homes by flying in or from houseplants that are already infested that are brought inside.
Fungus gnats infest soil and feed upon decaying or damaged plant roots as well as fungi found in the soil. While not dangerous to humans, a fungus gnat infestation can be a nuisance indoors, as clouds of these tiny pests swarm and settle repeatedly.
