West Nile Virus

VECTOLEX

What is VECTOLEX?

VECTOLEX is a larvicide that can kill mosquitoes during the larvae stage of its development. Its active ingredient contains a naturally occurring bacteria (Bacillus sphaericus) that is common in soils in the United States and throughout the world.

How does VECTOLEX work?

VECTOLEX comes in a granule form that contains the bacteria Bacillus sphaericus. These bacteria damage the gut of mosquito larvae when they eat it, causing the larvae to starve to death. These granules can be placed directly in the standing water areas where mosquitoes breed, or can be mixed with water and other substances, and sprayed from the air or ground.

Where is VECTOLEX used?

VECTOLEX is placed in wet areas where mosquitoes live and lay eggs, such as storm water and drainage systems (catch basins), and areas where standing water can collect, such as small ponds, large puddles, pool covers, and discarded automobile tires.

Is VECTOLEX harmful to humans?

Direct contact with VECTOLEX can cause mild eye and skin irritation, but there are no known serious effects.

How safe is VECTOLEX for the environment?

After being put in water, the bacteria are short-lived, and their toxins do not appear to be harmful to fish and most other aquatic organisms.

Is it safe for children and pets to play in areas that have been treated with VECTOLEX?

Mild skin and eye irritation can occur with direct contact, and it is best to keep children and pets away from areas that have been treated. However, since it will mostly be placed in storm drains and catch basins, children and pets will not have access to areas where VECTOLEX has been placed.

Am I likely to be exposed to VECTOLEX?

The larvicides are being applied in storm drains, catch basins and other areas to which the general public does not have access. These areas drain into river water and sewage treatment plants.

Can I use VECTOLEX around my home?

VECTOLEX can only be applied by licensed applicators.

What should I do if I am exposed to VECTOLEX?

If you are exposed to a larvicide, rinse the eyes with tap water for 20 minutes and wash the skin thoroughly with soap and water. If the symptoms persist, contact your doctor or local emergency department. You may also contact the New York City Poison Control Center at (212) POISONS (764-7667).
