![]() Bti vs Bs – Bacillus thuringiensis israelensis vs Bacillus sphaericusĪ similar product to Bti is Bacillus sphaericus (Bs) which is another bacterial biological control product. Older mosquito larvae tend to stop eating as they approach the next life stage, therefore Bti may not be as effective on older larvae and some adult mosquitoes may emerge after the initial Bti treatment. It can take several days for all of the mosquito larvae to die, so if you see no immediate results, don’t be alarmed.ĭon’t fret if there still appear mosquitoes upon treatment The crystals cause the stomach cells to explode, forcing the mosquito larva to stop feeding until it starves to death. When eaten by a mosquito larvae, “toxic crystals” form which travel to the stomach and enter the stomach cells. By the time it is sold to the consumer, it is no longer a living bacteria, however it is still just as effective in killing mosquito larvae. The inactivated bacteria is added to fillers and packed neatly into dry briquettes or pellets. Dunks and bits are produced by harvesting Bti from soil, then inactivating the bacteria with enzymes. Since Bti occurs naturally in the environment, it is considered an all-natural biological control product. (it’s very specific in its larvicidal activity) Bti is simply a different strain of Bt that only affects mosquitoes and black flies.Bt biocontrol products are often used on agricultural and garden pests, such as You may be familiar with Bt products as a common form of pest control originating in the early 1900s. They are one of the most effective products on the market today. Mosquito Dunks and Mosquito Bits are made from naturally occurring soil bacteria called Bacillus thuringiensis strain israelensis (for the rest of us: Bti). What exactly are mosquito dunks and bits? It should be noted that how long and well they work depends mainly on “the mosquito species, the environmental conditions, the formulation of the product, and water quality”. “Killing mosquito larvae with microbial larvicides before they emerge as adults can reduce or eliminate the need for ground or aerial application of pesticides to kill adult mosquitoes. To keep it plain and simple, yes, Bits and Dunks really work. Of course, for medium or small sized yards costs are much lower.ĭoes this larvicide really have to ability to kill mosquito larvae? If you have a really large yard you will be spending about 30 bucks a month so it better be worth it and work. While scratching your welt you wonder, Do they work? You have heard about Mosquito Bits and Dunks before. ![]() Which certainly goes for those vicious bloodsucking gits. ![]() Preparing your yard to reduce mosquito infestation.įounding Father Benjamin Franklin already said it, “An ounce of prevention is worth a pound of cure.” There´s something else this incident informs you about. The fresh joy of being outside basking in the Spring sun just became tainted. You look down and there it is: a giant, red, itchy welt. Your hand swats wildly *SMACK*, but nope. Suddenly that annoying buzzing around your ears. You’re sitting down for a meal outside with the family. ![]()
