Why Use a Mosquito Growth Regulator?
Mosquito growth regulators don’t kill mosquitoes immediately. Instead, they stop larvae from developing into adults by interfering with their normal growth process. That means fewer flying, biting mosquitoes in the future—and more sustainable control.
These products are especially useful when:
- Adulticide sprays can’t reach hidden breeding sites
- Populations rebound quickly after adult treatments
- Long-term, low-toxicity control is preferred
- Treating areas near sensitive environments (schools, wetlands, or homes)
Products like methoprene-based granules and liquid formulations are commonly used in both commercial and residential mosquito control programs.
Choosing the Right Larvicide for Mosquitoes
Larvicides eliminate mosquito larvae before they can emerge from the water. Depending on your site and application method, options include:
- Granular larvicides: Easy to broadcast over standing water
- Briquettes and Dunks: Ideal for long-lasting control in birdbaths, gutters, or ponds
- Liquid concentrates: Best for larger treatment zones like storm drains or floodwater areas
Many larvicides for mosquito control use Bacillus thuringiensis israelensis (Bti)—a naturally occurring bacterium that’s highly effective against larvae but harmless to people, pets, and wildlife.
Where to Apply Larvicides and Mosquito IGRs
For the best results, focus on mosquito breeding grounds. Common treatment sites include:
- Stagnant water in containers, gutters, or drainage ditches
- Decorative ponds, fountains, and birdbaths
- Storm drains, catch basins, and sewer systems
- Irrigation or agricultural runoff areas
Apply products as directed and monitor for signs of larval activity. If mosquito numbers stay high, consider combining IGRs with adulticides and traps as part of an integrated approach.
What is an IGR?
Mosquitoes carry many diseases that can harm you and your family, but you can get rid of them before they take hold with mosquito control products from DIY Pest Control.
FAQs About Mosquito Growth Regulators
Mosquito IGRs and larvicides are powerful tools for controlling breeding populations, but choosing the right product and using it correctly is key. Here are answers to the most common questions users have before applying these treatments.
What’s the difference between a mosquito larvicide and an IGR?
Larvicides kill mosquito larvae directly, while IGRs prevent larvae from developing into adults. Both target the early stages of the mosquito lifecycle.
Are larvicides safe for wildlife and pets?
Most mosquito larvicides, especially those with Bti, are considered safe for pets, birds, fish, and other wildlife when used as directed.
How often should I reapply larvicides or IGRs?
It depends on the product. Some briquettes last up to 30 days or more, while liquid treatments may require more frequent application after rain or flooding.
Can IGRs be used with other mosquito control products?
Yes, IGRs are often used alongside adulticides and traps in integrated mosquito management programs for broader and longer-lasting control.
Will mosquito IGRs affect other insects?
Most IGRs are insect-specific and have minimal impact on beneficial species when used according to label directions.
