Altosid XR-G is an insect growth regulator made for absolute mosquito control. It's a mosquito larvicide, so it targets the larvae and prevents them from growing into adults. It has the same active ingredient as other Altosid products but in easy-to-use granules. When used as directed, it reduces the mosquito population and protects against infestations for up to three weeks.

How Altosid XR-G Works

It contains the active ingredient s-methoprene, which mimics the mosquito's hormones. It affects the larva's growth cycle, so it can't mature into a breeding adult. It also prevents the mosquito's ability to reproduce, thus putting an end to population explosions. Though it works on larvae, it does not affect adult mosquitoes.

Where to Use Altosid XR-G

Adding Altosid XR-G IGR to standing water in the following areas and more will target the larvae and interfere with their life cycle:

  • Birdbaths
  • Old tires
  • Gutters
  • Pool covers
  • Water gardens

Altosid XR-G Prevents Mosquito Infestations
