Tiny bugs that you can’t see but definitely feel are one of the biggest warm-weather annoyances. If you’ve ever been bitten by invisible insects while relaxing outdoors, chances are you’ve met the no-see-ums, also called biting midges. These nearly microscopic pests can turn a summer evening or outdoor business space into a nightmare.
The good news? With the right combination of prevention, protection, and persistence, you can keep them away. Let’s explore how professionals recommend getting rid of no-see-ums for good.
Step 1: Know What You’re Dealing With
No-see-ums are not mosquitoes, though they’re just as annoying. They’re tiny flies often 1 to 3 millimeters long that breed in moist soil or organic debris. According to Terminix’s guide on no-see-ums, these pests can slip through regular window screens and bite through thin clothing. They’re most active at dawn and dusk when the air is humid and still.
“They may be small, but they pack a serious punch,” says a pest management professional. “You don’t need to see them to feel their presence or their bite.”
Step 2: Eliminate Their Breeding Grounds
The first and most effective step is cutting off their breeding sites. No-see-ums love moisture and decaying organic matter. Start by:
- Draining standing water around the home or business.
- Cleaning gutters and drains.
- Raking away damp leaves, mulch, or grass clippings.
- Reducing overwatering of lawns and gardens.
When homeowners manage moisture, pest activity can drop dramatically. One facility manager noted, “Once we fixed the leak behind our patio area, the no-see-um problem nearly vanished.”
For more details, UF/IFAS Extension explains that these biting midges breed in wet soil and decaying vegetation, making yard maintenance key.
Step 3: Strengthen Your Barriers
Because of their small size, no-see-ums can fly right through ordinary window screens. To block them effectively:
- Install fine-mesh screens (20-mesh or smaller) designed for no-see-ums.
- Use fans to create air movement in outdoor areas — they struggle to fly in strong airflow.
- Apply door sweeps and window seals to close small entry points.
- Add outdoor netting or enclosures to protect dining or relaxation spaces.
According to DynaTrap’s guide on no-see-um control, combining fine screens with traps and air movement significantly reduces infestations.
Step 4: Repel and Control the Adults
Even with prevention, some no-see-ums will find their way inside or around you. To protect yourself and your space:
- Use EPA-registered repellents containing DEET, picaridin, or permethrin-treated clothing.
- For natural alternatives, use lemon eucalyptus, mint, or camphor oils — Orkin recommends them for mild infestations.
- Set CO₂ or UV traps near outdoor seating areas to lure and capture adults.
- For commercial or large outdoor areas, consider professional-grade foggers or perimeter sprays — always applied by licensed pest technicians.
The EPA’s bed bug and insect control guide emphasizes using integrated pest management — combining safe chemical and non-chemical methods for the best results.
Step 5: Monitor and Maintain
No-see-ums are seasonal pests, but controlling them requires consistency. Keep an eye out for activity at dawn and dusk, and continue preventative maintenance even after they disappear. Small business owners should schedule regular inspections and keep communication open with pest control professionals.
The CDC’s insect bite prevention tips also stress long-term maintenance: staying proactive keeps infestations from returning.
Final Thoughts
Getting rid of no-see-ums isn’t about a single quick fix. It’s about combining smart prevention with the right professional tools. Drain standing water, seal openings, use traps, and apply repellents safely. With a steady, professional approach, you can make your home or business a no-fly zone for these invisible biters.
