Tools Needed

Altoside Liquid Larvicide may be applied by aircraft to terrestrial locations, ground application equipment, equipment capable of applying a fine mist or ULV, backpack sprayer, or handheld pump sprayer. We recommend making applications through ULV spray equipment to cover a broader range of terrain.

Do not apply this product through any irrigation system unless the supplemental labeling on chemigation is followed.

How to Use

• Step 1: Examine your yard and observe areas that has past water accumulation activity or falls under the approved sites to treat.
• Step 2: Determine how much Altosid Liquid Larvacidie to use by measuring the square footage of the treatment area. To find this, measure the treatment sites length and width in feet and multiply them together (length X width = square footage). To find acreage, take the square footage and divide it by one acre (square footage / 43,560 = acre) For control of mosquito larvae using ULV application equipment apply at the rate of 3 to 4 oz. of Altosid Liquid Larvicide per acre to water holding containers and other small bodies of water. For aerial application, apply at the rate of 3 to 4 fl. oz. of product per acre diluted with water at a minimum of 1:1 mix ratio with water. Do not mix with oil and use clean equipment.
• Step 3: Partially fill the selected sprayer with half the amount of water, then add the measured amount of Altosid Liquid Larvicide, and pour in the remaining half of water. Close the sprayer lid and gently shake to mix the product solution.
• Step 4: Apply the Altosid Liquid Larvicide around and to terrestrial locations by ground or from the air. Reapply when breeding sites become reinfested or when adult population has increased.
