MOSQUITO PUCKS
If you find yourself battling fungus gnats it is best if you arm yourself with as many tools as possible for the fight. In addition to the arthropods the OIF offers to counter this pest, we also sell mosquito dunks. These pucks can be placed in your watering can to soak and release Bt, a bacterium that not only kills the larvae of mosquitoes but also has proven effective in killing the larvae of fungus gnats as well. 
Bt is proven to be very targeted in what it selects for prey, and non-target insects, aquatic animals, pets, and humans are not affected by its presence.
