Will Mosquito Dunks Kill Dragonflies?

Mosquito dunks, or briquettes of Bacillus thuringiensis israelensis (Bti), are a biological control agent used to kill mosquito larvae. They are effective for about 30 days and release a biocontrol agent that the mosquito larvae will eat. The bacterial toxin kills them as well as black fly larvae.

The purpose of mosquito dunks is to control mosquitoes and psychodid flies and their larvae. However, concerns have been raised about the potential harm to dragonfly larvae. Bti is considered non-toxic to most organisms, except some Diptera such as chironomids. If mosquitoes remain a concern, BT mosquito dunks/rings can be added to the water. These dunks release naturally occurring bacteria that only harm fly larvae, not damsel, dragonfly, or amphibian larvae.

Mosquito dunks are formulated to target only mosquitoes and are harmless to other animal species. If mosquitoes are still a concern, BT mosquito dunks/rings can be added to the water. They release naturally occurring bacteria that only harm fly larvae, not damsel, dragonfly, or amphibian larvae.

A side note on dragonfly/damselfly larvae: While many people use mosquito dunks to filter their pond, they may not kill dragonfly nymphs. The filtering process is successful, as the bacterium released by Bt israeliensis kills mosquito larvae but does not harm young dragonfly nymphs.

Can You Put Mosquito Dunks In A Fish Pond?

Gibbs recommends utilizing mosquito dunks, small discs that release a bacterium targeting mosquito larvae while being safe for other aquatic life, such as dragonflies and fish. These B. t. i. (Bacillus thuringiensis israelensis) containing dunks can be placed in various water features like koi ponds, fountains, and water gardens without harming fish, frogs, or other aquatic animals. They are particularly effective at controlling mosquito and blackfly larvae, making them an excellent choice for anyone looking to manage mosquito populations in areas with standing water.

Studies indicate minimal irritation risks associated with using mosquito dunks, even if ingested or if they come into contact with skin. Users can safely introduce them into backyard ponds and similar environments where the presence of aquatic life is prevalent. In addition to mosquito dunks, one can enhance the attraction of dragonflies by incorporating specific plants into their garden.

While these dunks work effectively in different aquatic settings, it is essential to adhere to guidelines regarding their application. For example, they should not be used in larger bodies of water like streams or lakes but are appropriate for smaller containers and backyard volumes akin to small fish ponds. When deploying mosquito dunks, breaking them into smaller pieces can help treat specific areas without overloading the ecosystem.

Moreover, the presence of fish in ponds naturally deters mosquito breeding, as toxins released by mosquitos are harmful to them. Therefore, maintaining a balanced aquatic habitat can significantly reduce mosquito populations. Overall, using mosquito dunks is a viable solution for controlling mosquito larvae while ensuring the safety and well-being of other aquatic creatures and enhancing biodiversity in garden ecosystems.
