Bacillus thuringiensis israelensis (Bti) is a type of bacteria that is commonly used as a natural pest control agent. It is found naturally in the environment and is used to control a variety of insect pests, including mosquitoes, blackflies, and gnats.
Bti produces proteins that are toxic to certain insects, but are generally safe for humans, animals, and the environment. When ingested by the target insects, the proteins bind to receptors in the gut and create pores that cause the insect's gut lining to break down, leading to death.
Bti is often used as a biological control agent in mosquito control programs, as it is effective at killing mosquito larvae while posing minimal risk to non-target organisms. It is also used to control other insect pests in a variety of settings, including gardens, greenhouses, and agricultural fields.
Bti is generally considered to be a safe and effective pest control option, but it is important to follow the manufacturer's instructions and use it according to label directions to ensure its safe and effective use.
