Q: What is ALTOSID?

A: ALTOSID is a trade name for the generally used product Methoprene. Methoprene is an insect growth regulator used to control many types of insects. It has also been used for many years as a pesticide in the processing of foods like meat, milk, eggs, mushrooms, peanuts, rice and cereals.

Q: How does ALTOSID work?

A: ALTOSID interferes with the normal life cycle of an insect. By mimicking an insect growth hormone, it prevents the development of adult mosquitoes from larvae.

Q: Where is ALTOSID used?

A: ALTOSID is applied to 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 and puddles, pool covers, and discarded automobile tires. Briquettes (small blocks) of ALTOSID are placed in these areas, where they will slowly release larvicide for either 30 or 120-150 days, depending on the type of preparation. Liquid forms of ALTOSID may also be used.

Q: Why is this specific product being used?

A: ALTOSID has been chosen for use as a larvicide in Salt Lake City because of its long safety record for humans and pets. It is effective if used early, before adult mosquitoes develop.

Q: Is ALTOSID harmful to people?

Research has not shown ALTOSID to be harmful to humans. Direct contact can cause mild eye and skin irritation, but no known serious health effects have been found. The U.S. Environmental Protection Agency (EPA) has placed Methoprene into the category of "least toxic" with regard to humans.

Q: How safe is ALTOSID for the environment?

A: Once it is released from the briquette, ALTOSID is rapidly biodegradable and breaks down quickly in water and sunlight. It does not remain in the ground.

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

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

Q: Can I use ALTOSID around my home?

A: ALTOSID can only be applied by licensed applicators.

Q: Am I likely to be exposed to ALTOSID?

A: Larvicides are applied in storm drains, catch basins and other areas to which the general public does not have access.

Q: What should I do if I am exposed to ALTOSID?

A: 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.
