Target Pests

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.

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?

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.
