Mosquito Bt Floating Dunks Pack of 20
Mosquito Bt Floating Dunks Pack of 20
Mosquito Bt Floating Dunks come in a Pack of 20 as an eco-friendly mosquito control solution. They are doughnut-shaped tablets containing Bacillus thuringiensis subspecies israelensis (Israelensis BTi) that target mosquito larvae in standing water while being harmless to humans, pets, and other wildlife. Each dunk slowly releases the active ingredient to help disrupt the mosquito life cycle, making them suitable for long-term use in ponds, rain barrels, and birdbaths.
BT mosquito dunks release Bt into standing water. When mosquito larvae or fungus gnat larvae ingest the bacterium, Bt toxins disrupt their digestive system, causing death within hours and preventing adults from developing. Use in standing water breeding sites such as ponds, bird baths, animal watering troughs, unused swimming pools, flower pots, rain barrels, and roof gutters to reduce mosquito bites.

Really nice soil and awesome service
Never used because I ordered the wrong Water Filter. Mike was very helpful with the return and refund. Excellent Customer Service.
Great service. Soil is what I wanted and it off loaded exactly where I asked.
Plants are doing really well with this soil. Deep and rich looking soil, plants seem really happy. Much more cost effective (and no plastic bag waste) compared to buying bags of soil mix from a store.
Thank you for shipping so soon. Great service
The quality of the craftsmanship is superb! My formula one fan absolutely loves it!!!!
Worked like an absolute charm!
These markers were perfect for ones that we were replacing. The quality is great and they seem sturdy. The gold detail stands out and is visible from a distance. Shipping was very fast.
Good solution. The little flies have disappeared. We were sure to mist/moisten the surface of each plant once a day for 4 or 5 days, after the initial application of the nematodes, to keep the little guys mobile and able to get to any remaining eggs. So, go for it!
Plant was well packed and shipment was very fast. Received a very nice fully rooted plant in the pot!
The organic garden soil is doing very well in my garden bed. The company was professional, nice, and accommodating to my needs. They provide many types of things for your landscaping at a reasonable price.
