Target Pests

Altosid Pro-G is designed to prevent mosquitoes from breeding and becoming biting adults

For Use In

Non-Crop Areas: Altosid Pro-G may be applied as directed above to temporary and permanent sites which support mosquito larval development. Examples of such sites include: snow pools salt and tidal marshes freshwater swamps and marshes (cattail red cedar white maple marshes) woodland pools and meadows dredging spoil sites drainage areas ditches wastewater treatment facilities livestock runoff lagoons retention ponds harvested timber stacks swales storm water drainage areas sewers catch basins tree holes animal watering troughs water holding receptacles (e.g. tires urns flower pots cans and other containers) and other natural and manmade water-holding depressions.

Crop Areas:Altosid Pro-G may be used in sites such as: irrigated croplands pastures rangeland vineyards rice fields (domestic and wild) date palm citrus fruit nut orchards berry fields and bogs.


Apply product at any stage of larval mosquito development. Granules may be applied prior to flooding (i.e. pre hatch or pre flood) in areas which flood intermittently. In such areas, one application of Altosid Pro-G can prevent adult mosquito emergence from several subsequent floodings. The actual length of control depends on the duration and frequency of flooding events.

Sprays such as Vector Ban Plus or Cyonara 9.7 are great choices to apply on mosquito harborage sites to eliminate adult mosquitoes.

Altosid Pro G Mosquito Larvacide

Altosid Pro G Mosquito Larvacide

Altosid Pro G Mosquito IGR Lavacide is a great product to put a stop to mosquito larvae, stopping a new generation of pesky moquitoes from growing and creative problems. Altoside contains (S)-Methoprene 1.5% which effectively kills mosquitoes before they hatch. Scatter the granules in areas where mosquitoes may breed to prevent them from reaching adulthood. When carrying out a mosquito control program, it would be wise to consider using insect growth regulators (IGR'S) since adult mosquitoes aren't the only problem to deal with.


Altosid Pro G should ideally be applied in water where mosquitoes breed. Some of the prime areas around the home which can be breeding grounds for mosquitoes include: bird baths, flowerpots, ornamental fountains, gutters, rain barrels, pool covers, puddles, horse troughs, and other water-holding receptacles. 1 package of Altosid Pro G (2.5 lbs) can cover an area of 5,445 sq ft or 20,183 gallons of water and remains effective for up to 30 days.


How to Apply Altosid Pro G Larvacide

Altosid Pro G is fairly simple to apply. The granules put a stop to mosquito larvae transitioning into adults, including those which may transmit harmful diseases such as West Nile and the Zika virus. Altosid can work for up to 30 days after application. Applications should be continued throughout the mosquito season to maintain adequate control.Treated larvae continue to develop normally to the pupal stage where they die.


Using the application rate table which comes on the product label,  measure and then scatter the suggested amount of Altosid Pro G evenly over the surface of the water to be treated. For continued mosquito control, you should apply Altosid pro G every 30 days throughout the season. When used according to the product label, this product will not cause any adverse affects in humans, animals, fish or vegetation.


Additional Mosquito Treatment Tips

  • Mosquitoes lay their eggs in standing water. We recommend that aside from using Altosid Pro G, you do your due diligence to remove, reduce or treat any stagnant bodies of water in receptacles or containers in your yard.
  • Stagnant water can be treated with IGRS such as Altosid Pro G IGR . This product prevents developing mosquitoes from ever reaching the adult stage.
  • Remove litter from your yard. Mosquitoes can lay eggs in small, discarded items that can hold water such as cans, bottles, and wrappers. Stay indoors during dawn, dusk, and early evening when mosquitoes are more likely to bite.

Can you deleate this in water then use sprayer to spray?
Dawg on Aug 10, 2016
BEST ANSWER: Altosid Pro G is not meant to mixed with water and sprayed. It is to be sprinkled in the standing water areas.

Better to use a mosquito control sprays such as Cyzmic to spray all the area to better control your populations.
is this safe for dogs? I have a little 9 pound min-pin who frolics around the pond/waterfall, will this burn his feet or poison him if ingested?
K on Jun 16, 2016
BEST ANSWER: No this will not harm your dog, you can use a dunk if you want it to be more controlled.

Altosid PRO G Mosquito Larvacide
We start using this product around the end of February beginning of March around the areas that hold water, even if they're dry, and keep treatment going through the season. So far as we've been using it, it's worked great.
