Human stomachs are acidic, not alkaline, so they digest the Bt toxin. However, some products are used in the form of a dust, and there have been a few instances of allergic reaction to the dust when the product was applied. Just to be safe, you should wear gloves, long sleeves, and trousers when you apply the microbial insecticide.

And then wash thoroughly afterwards. Like any pesticide, the targets of Bt can develop resistance, although this rarely happens.

The diamondback moth, a pest of cabbage and other cruciferous plants, is the primary example of an insect that has developed resistance in the field. If you use Bt on your farm, the EPA will require you to take some steps to prevent resistance. One way is to alternate its use with synthetic insecticides. Another is to rotate your crops. Since different kinds of insects feed on different crops, you would be using a different type of Bt. The large variety of Bacillus thuringiensis strains available enables gardeners, farmers, and mosquito control experts to control an array of insect pests.

Since the strains are highly specific to the insects targeted, residual effects against other organisms are not a concern. The widespread usage of Bt has been a boon to farmers and to people who are now sprayed with these bacteria to kill mosquitoes instead of DDT! See our TOS for more details.

Fascinated by the childhood discovery that plants make chemicals to defend themselves, Helga embarked on further academic study and obtained two degrees, studying plant diseases as a plant pathology major.

Is this possible, or do I have to sacrifice the potentially harmless or beneficial larvae to … Read more ». Hi Janis, Thank you for your question! BTI kills only mosquito, blackfly, and fungus gnat larvae, so the other creatures in your pond should be safe.

Helga, there are many types of desirable fly larvae that occur in ponds and streams, some fairly closely related to mosquitoes and or blackflies. Chironomidae are among them, and there are a few thousand species of those. Are they killed by BTI? Dear Dr. McNeely, Thank you so much for your informative question! Apparently, the larvae are much less sensitive to BTI than some mosquito larvae are times less sensitive. However, it seems as if people do try to control them sometimes, because the adult midges can be considered a problem to the general public and industry.

The susceptibility of the flies varies by subfamily: the Chironominae are the most susceptible, although the filter feeders are more likely to ingest BTI than the predators, collector-gatherers, shredders, or scrapers. Members of the Tanypodinae group are the … Read more ». I feel like I waste a lot trying to squeeze the dust out of the container. Would it be OK to mix it with water and spray plants with a small hand sprayer? How much BT powder should I mix with a given volume of water? Hi Linda, That does sound like a pain.

If you let me know, I may be able to lead you to a BT powder that is meant … Read more ». What type of insects are you trying to control, Linda? Safer makes a similar product that I use, which comes in a liquid concentrate that you mix with water and spray on plants. You can find it here, on Amazon. But keep in mind that different types of Bt are meant to target different varieties of insects.

Hello everyone. Can we inoculate the BT into honeycomb mesh for slow and continuous release in running drain water to increase the population in continuous manner?
