It contains spores that produce toxins that specifically target and only affect the larvae of mosquitoes. Bti has no toxicity to people and pets, and is certified for treatment of organic crops. Since the material is suspended in water, the application will also not harm the finishes on cars or homes.

Commonly Asked Questions
1. What is a mosquito control treatment?
The District will conduct a mosquito control treatment to reduce the the number of mosquitoes emerging into biting adults. Treatment locations will include an area in Studio City between Colfax and Tujunga, and Moorpak and LA River. GLACVCD personnel will be applying a biological larvicide called Bacillus thuringiensis israelensis (Bti). It is a naturally occuring soil bacterium that is specific to targeting mosquito larvae only. It is safe for other insects, fish, birds, humans, and pets. It is also approved for use on organic crops.
2. Why is this being done in my neighborhood?
Due to the high abundance of mosquitoes collected in our traps in the area, coupled with high numbers of mosquitoes infected with West Nile virus, and historically high numbers of West Nile virus activity, the District is conducting a mosquito control treatment to reduce West Nile virus threats. The goal of the treatment is to reduce the numbers of mosquitoes and virus presence, and lower the risk of human infections in the area. This particular area of Studio City has been identified to have the most favorable conditions for this treatment to be most effective.
3. What can I do to prepare?
You DO NOT need to do anything to prepare your home for the treatment. There is no need to close your doors or windows during the treatment, however you may do so to achieve personal comfort. The truck will drive by your home for only a few seconds.
4. Is Bti harmful to wildlife including honey bees?
Studies indicate Bti has minimal toxicity to honey bees. Bti produces toxins that specifically affect the larvae of only mosquitoes and some closely related fly species. These toxins do not affect other types of insects including honey bees.
5. What other measures should be taken to control mosquitoes besides Bti treatment?
- Eliminate standing water around your home to prevent mosquitoes from laying their eggs on your property
- Close or repair all unscreened doors and windows to prevent mosquitoes from entering your home or workplace.
- Wear insect repellent containing CDC and EPA-approved active ingredients: DEET®, Picaridin, IR3535, or oil of lemon eucalyptus. They are most effective when used according to the label.
