The results show that simple Bti exposure does not kill the dragonfly nymphs within 4-24 hours as it does with the mosquito larvae. The dragonfly gut, therefore, must not be an alkaline environment with enzymes that release the pro-toxins produced by Bti.

Biotic factors are living organisms that affect other living organisms. Some examples of Biotic factors are fish, insects, and animals.

Dragonflies are important to their environments both as predators (particularly of mosquitos) and as prey to birds and fish. Because these insects require stable oxygen levels and clean water, scientists consider them reliable bioindicators of the health of an ecosystem.

All dragonfly nymphs are fierce and voracious predators. They kill and eat any animal that they can catch including shrimp and fish of their size.

Yes! Mosquito dunks are 100% effective in killing mosquito larvae. It can also even work on fungus gnats and black flies. Dunks are effective in getting rid of mosquito larvae on ponds, swimming pools, creeks, swamps, rain gutters, barrels or pots with collected rainwater, and water puddles.

Mosquito Dunks are safe to use around people, pets, birds, wildlife and fish. Mosquito Dunks have been registered by the EPA for use in animal watering troughs and fish habitats.

They are effective on mosquito and blackfly larvae, and have been recommended for use in backyard ponds or fountains where fish, frogs, tadpoles, and other aquatic animals live.

Mosquito Dunks® are also safe for use around birds, wildlife, children and pets. Even if your dog eats an entire Mosquito Dunk®, this will not adversely affect the animal. If an animal eats a Mosquito Dunk® or drinks water treated with a Mosquito Dunk®, it essentially gets a large dose of protein and calcium.

Mosquito Dunks are safe for all humans and animals, as well as plants and other living organisms. They also won’t damage any mechanical equipment that you might have in the water that you want to treat with the Dunks.

Mosquito bits are roughly the same as dunks. They’re made from the same microorganism, and they work in the same way. However, they do differ in size and the time it takes for them to show results.

Just mix 4 tablespoons of Mosquito Bits® in 1 gallon of water. Let the Bits soak for 30 minutes to remove the BTI, then skim off the floating granules. (You can also place the Bits in a nylon stocking prior to immersing them in water. That makes it easier to remove the granules, which can be composted or discarded.)
