Summit by White Mountain Mosquito Dunk - Mosquito Larvicide - 2 Pack

These dunks work very well to kill all mosquito larva in rain barrels. They can be placed in the barrel whole, one to a 55-gallon barrel. I like to break one in half and rub the two halves together to get a distribution of particles on the surface of the water. It kills all larvae in a few hours. While I do not recommend treating drinking water meant for human consumption, I do use the treated water for chickens with no ill effects.

Fight mosquitoes the environmental way. Safe for pets and humans. Simply drop it in the still water and it stop wrigglers before they can take flight.

kills mosquito larva in rain barrels and other collection areas, very effective. Also doesn't affect pets as my pup ate several with no ill effects.

Works amazingly for mosquitoes controls.

We have been using this product for a long time and it works. We especially like putting the dunks in our rain barrels and fountain to keep the mosquitoes at bay. The Market Seller we purchased them through on the Walmart Website got them to us on time and in good condition.

Multiple delays in shipping. Product arrived with pieces broken
