Flies & Gnats

Flies, Gnats & Flying Pests — fast, targeted pest control that’s safe for your space and guaranteed to work

Why You’re Seeing Flying Pests Indoors

Flying pests inside your home almost always point to an underlying issue — moisture, decaying organic matter, a drain problem, or an exterior entry point. Spraying them as they fly doesn’t solve the problem. We find what’s attracting and breeding them, eliminate the source, and prevent them from coming back.

Signs You Have a Fly, Gnat or Flying Pest Problem

Most indoor fly problems start with a hidden breeding source. Look for:

  • Small flies hovering near drains.
  • Gnats around houseplants.
  • Fruit flies near trash, fruit bowls, or recycling.
  • Slow‑moving flies appearing suddenly in winter.
  • Mosquito activity near standing water.

Common Questions Answered Simply

Fungus gnats breed in houseplant soil — not dirty kitchens. Fruit flies often come from drain biofilm, not fruit bowls.

No. They don’t bite or sting. Their impact is environmental — they damage trees and plants.

Because the breeding source is still active. A fly can lay 100–150 eggs at a time. Killing adults doesn’t stop the cycle.

Why Flies and Gnats Are Common in Elizabeth, NJ

Flies and gnats are especially common in Elizabeth because of dense housing, older buildings, and mixed residential–commercial areas. Restaurants, dumpsters, shared trash rooms, and alleyways create plenty of food and moisture sources.

In apartments, overwatered houseplants, slow drains, and shared plumbing lines give fungus gnats and drain flies ideal breeding spots. Warm summers, humid weather, and standing water around properties also boost mosquito and house fly activity.

Even if you keep a very clean home, nearby conditions in the building or neighborhood can still lead to indoor flying pests, which is why we focus on finding and fixing the true source, not just spraying what you see.

How We Treat Flies, Gnats and Flying Pests

Identify the species and find the breeding source

We determine whether you’re dealing with fruit flies, drain flies, fungus gnats, mosquitoes or another species — then trace activity back to the exact breeding site.


Eliminate the source and treat shelter areas

We recommend source removal (drain cleaning, waste changes, plant soil adjustments) and apply GreenPro‑certified treatments to active areas. For restaurants, we use food‑safe products that meet NJ health code.


Prevention tips and follow-up

We identify torn screens, door gaps, open drain lines, and other entry points.
Flies entering from outside cannot be treated away without closing the gaps. If they return in 30 days, so do we, free of charge.
