Battling Flies & Gnats in Houston — What Every Homeowner Should Know

Battling Flies & Gnats in Houston — What Every Homeowner Should Know

If you’ve noticed more flies and gnats around your home lately, you’re not alone. This is one of the most common complaints we hear from homeowners across the Houston area this time of year.

Our warm, humid climate creates the perfect breeding ground for these pests—especially as temperatures rise and we get those frequent rain showers. Standing water, lush landscaping, and even everyday household items can quickly turn into ideal conditions for flies and gnats to multiply.

The good news? There are some very effective ways to get ahead of the problem.

Here’s what works best:

1. Eliminate breeding sources (this is the most important step)

• Check for standing water (plant saucers, gutters, low spots in the yard)
• Keep trash cans tightly sealed and cleaned regularly
• Avoid overwatering plants (indoors and out)

2. Keep drains and disposal clean

• Gnats love organic buildup in sinks
• Flush drains weekly with boiling water or a vinegar + baking soda solution

3. Use simple traps that actually work

• Apple cider vinegar + a drop of dish soap in a small bowl attracts and traps gnats
• Sticky traps for indoor plants can quickly reduce populations

4. Maintain your yard

• Pick up pet waste promptly
• Keep grass trimmed and landscaping tidy
• Consider mosquito/gnat yard treatments if the issue is persistent

5. Seal up entry points

• Check window screens for tears
• Make sure doors seal tightly
• Repair gaps around windows and exterior doors

A few things many homeowners don’t realize:

• Overripe fruit – especially BANANAS – on the counter is one of the biggest indoor attractors
• Dirty trash bins (even if lined) can still harbor eggs
• Gutters clogged with debris can quietly become a major breeding zone
• Indoor plant soil is often the source of gnats inside the home

If you stay proactive, you can usually keep this from turning into a bigger issue.
