Mosquito Larvae in Wildlife Pond: Natural Control

Identification

Small, squirmy, wiggling at surface, black spots, no legs, reproduce fast = mosquito larvae.

Larvae don't harm newts, but adult mosquitoes are pests.

Add fish: 2–3 goldfish or mosquito fish (Gambusia) eat all larvae. Best long-term solution.
Bti (Bacillus thuringiensis israelensis): Mosquito Dunks or Bits. Safe for all wildlife except mosquito larvae. Apply monthly.
Remove standing water elsewhere in garden.

Fish are the primary predators. Without them, larvae thrive.
