Mosquito Dunks 20 pack Bt israeliensis

Quick Kill Mosquito Dunks kill mosquito larvae for 30 days or longer when placed in standing water outdoors. Dunks will float in water and can be anchored with string to prevent them from being washed away. Alternate drying and wetting does not reduce their effectiveness.

Application of Dunks: Use 1 dunk/100 sq. ft. of infested water. Dunks also can be used as a pre-flood treatment in areas expected to become breeding sources.

Bti is a bacteria that controls mosquito and black flies in their larval filter feeding stage of development. The mosquito larvae die after consuming the bacteria that causes a disease specific to them but are harmless to all other forms of wildlife.

Availability: Ships in 1-2 business days.

Mosquito Dunks - By sandy A on Jul 24, 2010
I have used the mosquito dunks for years and I LOVE them!! They work great at controling the mosquitos in the standing water around here after the monsoons. My neighbors use the dunks also and we have very few mosquitos as a result. Thank You!

I have a small pond, half acre or so. These work great. I'll be ordering more soon.

I have used these in the past starting in April. Very easy and safe to use and have put a big dent in the population of mosquitoes.

Seemed to work well within 24 hours. Used with two small fountain pools and had to cut in half.

They work well - By Karen D. on Jul 16, 2011
We have standing flood water & the Dunks, along with Mosquito Bits, have really helped to cut down the mosquito population. This is our 3rd year to use them, but the first flood year. We're very glad we found them in larger quantities than the local stores carry as it reduced the cost.

I love these - By Donna on Aug 11, 2011
I noticed a decrease around the horses about a week after I started using the dunks again.

This year I have kept the mosquitos under control with your dunks. My neighbors noticed the lack of mosquitos too. I tell my friends "these are what you need".
