Mosquito Control for Large Collections: Dunks vs. Bits for 30+ Trays

Managing mosquitoes across 30+ water trays requires both immediate and long-term solutions. Both Mosquito Dunks and Mosquito Bits use Bacillus thuringiensis israelensis (Bti)—safe for plants, animals, and beneficial insects.

Product Comparison

Nursery Strategy

Sarracenia Northwest uses both products simultaneously every summer:

• Dunks in all trays for continuous protection
• Bits for trays showing active larvae
• Zero plant toxicity observed over years of use

Safety Profile

Bti specifically targets mosquito/fungus gnat larvae (Diptera). Harmless to plants, mammals, birds, amphibians, bees, and beneficial insects. The "insecticidal toxins" are crystalline proteins activated only in alkaline insect guts—mammalian digestive systems are acidic.
