Identifying and Repelling Biting Lawn Insects: Mosquitoes vs. Gnats

The Culprit

Swarming, biting, gnat-like insects when walking on the lawn. In Wyoming, similar tiny mosquitoes swarmed legs and inflicted painful, swollen bites.

Natural Repellent

• Lavender body spray or powder – applied to skin, deters biting.
• Avoid DEET-based products (toxic).

Lawn-Level Management

• Eliminate standing water (breeding sites).
• Encourage predators: bats, birds, dragonflies.
• Consider Bacillus thuringiensis israelensis (Bti) dunks in water features—targets mosquito larvae only.

If bites are severe or disease risk exists (West Nile, etc.), consult local health department for targeted control.
