Preventing Mosquito Breeding in a Solar-Powered Fountain with Intermittent Flow

Fix the Flow

Add a solar battery backup (e.g., OASE) so the pump runs 24/7. Moving water prevents mosquito egg-laying.

Biological Control

Use Bti (Bacillus thuringiensis israelensis)—Microbe-Lift Liquid Bti. Safe for fish, birds, pets. Kills mosquito larvae only. Apply weekly during season.

Details
