Just wondering if Yates caterpillar control is safe for wild birds drinking water?

Hi, I believe bacillus thuringiensis kurstaki is the active ingredient in Yates caterpillar control product. I understand that this ingredient will kill mosquito larvae. As we cannot get mosquito dunks in Australia, I am wondering if this would help. I want to put it into a pond (no fish) where our wild birds drink from so it needs to be safe. Alternatively, do you know of any other product that will help? Thank you so much.

Answer: Hi Jo,
The strain of bacillus you are referring to is not the same strain of bacillus that is in the Yates product, Dipel. There are no claims on the label to say that it will kill mosquito larvae. Bacillus thuringiensis which is the active in the Yates product Dipel is registered for the control of various leaf eating caterpillars on vegetables and ornamental plants. We do not have registration for this product to be used for any other purpose than what is on the label.

I am unsure of where you would be able to purchase the strain of bacillus you are looking for.

You would need to be careful that you use a registered product as you have mentioned in your email, you would not want to harm any wild life that may drink from the water you have treated. I wish you success in finding what you need.
