Our Inspection Process

Our licensed technicians perform a thorough interior and exterior inspection to confirm fungus gnats activity, identify harborage, moisture, and food sources, and map entry points. Findings are documented with photos and a written treatment plan tailored to your Hudson Valley, NY home.

Treatment Process

Let soil dry between waterings, apply BTI (mosquito bits) drench, apply yellow sticky cards, and treat surrounding area.

Integrated Pest Management

Urbanxterminator uses Integrated Pest Management (IPM) for fungus gnats: inspection, monitoring, sanitation guidance, mechanical exclusion, targeted low-impact products, and follow-up verification. We prioritize methods that are effective for you and your family while minimizing environmental impact.

Prevention Tips

  • Water plants less often
  • Use well-draining potting mix
  • Cover soil with a layer of sand or gravel
