Vector Control

Biological Vector Control Solutions

Target pests precisely with safe, eco-friendly microbial solutions. Our BTI and BTK formulations offer effective control of mosquito larvae and crop-damaging caterpillars without harming people, animals, or beneficial insects.

BTI – Mosquito & Fly Larvae Control

BTK – Caterpillar Control

Feature	BTI	BTK
Full Name	Bacillus thuringiensis subspecies israelensis	Bacillus thuringiensis subspecies kurstaki
Primary Target	Dipteran larvae (flies and mosquitoes)	Lepidopteran larvae (butterfly and moth caterpillars)
What It Kills	Mosquito larvae, Blackfly larvae, Fungus gnat larvae	Armyworms, Cabbage loopers, Diamondback moths, Tomato hornworms, Corn borers, Tent caterpillars
Where It Works	Aquatic/Water environments (ponds, puddles, water tanks, soggy soil)	Terrestrial/Leaf surfaces (crop canopies, garden leaves, trees)
How It's Used	Applied to standing water (spray, dunk, granules).	Sprayed directly on plant leaves where caterpillars feed.
Mode of Action	The toxin dissolves the gut lining of mosquito/fly larvae.	The toxin creates holes in the caterpillar's gut, stopping feeding.
Safety	Highly specific. Safe for humans, pets, birds, fish, bees, and other insects.	Highly specific. Safe for humans, pets, birds, fish, bees, and most beneficials (except caterpillars).
Common Form	Mosquito dunks/tablets, water-soluble granules, liquid.	Liquid concentrate, wettable powder, dust for spraying.
Popular Brand Names	Mosquito Bits, Mosquito Dunks, Aquabac	Dipel, Thuricide, Biobit

Use BTI when you have a problem with pests that breed in water.

How to use it: Drop a “mosquito dunk” in your rain barrel or mix granules into the top layer of soggy potting soil. It kills only the larvae, not adult insects.

Use BTK when you see chewing caterpillars damaging your plants.

How to use it: Mix the liquid or powder with water and spray it thoroughly on plant leaves, especially where you see caterpillar damage or eggs. The caterpillar must eat the treated leaf to die.

Common Advantages of BTI and BTK

Key Takeaways for Farmers & Gardeners

Match the Pest: Identify your pest correctly. Caterpillars = BTK. Mosquito/Fly larvae = BTI.
Match the Environment: BTI works in water. BTK works on leaves.
Timing is Key: Both must be eaten by the larval stage to work. They are ineffective against adult insects.
They are NOT interchangeable: Using BTK on mosquitoes or BTI on caterpillars will have zero effect.

Conclusion

Think of BTI as your “mosquito specialist” and BTK as your “caterpillar specialist.” By understanding this simple distinction, you can harness the power of these brilliant biological tools effectively, protect your crops and health, and maintain a balanced ecosystem without resorting to harsh chemicals.
