S2 Ep457: Better Lawns and Gardens - Hour 2 The Science Behind Mosquito Bits June 13, 2026

Mosquito control isn't just about killing adults—it's about disrupting their life cycle at the larval stage, and the most effective, eco-friendly tool for that is BTI, a naturally occurring bacterium found in Summit Responsible Solutions' mosquito bits and dunks. Teresa Watkins and guest Heather Stickney reveal that these products are safe for humans, pets, birds, fish, and pollinators—targeting only mosquito and fungus gnat larvae. A surprising twist: the foaming and wriggling seen in standing water after dunking isn't the product itself reacting, but likely surfactants in the water or pre-existing larvae becoming active. The episode debunks myths, like the need for large water bodies—mosquitoes can breed in a thimbleful—and offers practical, science-backed solutions for everything from backyard ponds to camping trips. The real takeaway? Prevention through targeted, sustainable tools beats reactive spraying, especially in Florida’s high-mosquito season.
