Where it can and can't go
Labeled sites include catch basins, tree holes, birdbaths, rain barrels, flooded roofs, abandoned pools, discarded tires and other containers, plus ditches, lagoons and retention ponds that don't drain straight into natural waters.[1]
Group 15 benzoylureas block chitin, so larvae die when they try to molt. That is why the label says fully developed adults aren't affected.[1][2]
Where it is used
One dose lasts up to 90 days at the high rate or 60 days at the low rate. Water that turns over often or holds lots of organic matter may need retreating sooner.[1]
Because it works only on larvae, start at the beginning of mosquito season and keep treating until the last brood of the year.[1]
Don't apply during rain or when rain is expected before the product has at least 4 hours to dry. Sweep stray granules off driveways and sidewalks.[1]
If you measure with spoons or cups, don't use them for food afterward. The label's chart treats 1 tablespoon as about half an ounce of granules.[1]

Safety and environmental hazards
People
Signal word CAUTION. Wash hands with soap and water after handling, and wear protective gloves when spreading granules by hand.[1]
Pets
Store it where children and animals can't reach it. In horse troughs it is allowed only for horses not intended for slaughter, and never use it in drinking water containers.[1]
Bees and pollinators
The label carries no bee warning; the granules go into water to target aquatic larvae.[1]
Fish and water
Toxic to freshwater and saltwater invertebrates. Use it only at sites that don't drain directly into natural water bodies, and keep granules out of storm drains, ditches and gutters that lead to water.[1]
Common questions
- Can homeowners use novaluron mosquito granules?
- Yes. The label says it can be used by homeowners as well as by mosquito control programs and pest control operators.[1]
- How much do I put in a rain barrel?
- Dose by water volume: 1.2 to 6 grams per 10 liters, about 2.6 gallons. Use the higher amount for water with lots of leaves or other organic matter.[1]
- Will novaluron kill the mosquitoes biting me now?
- No. It affects only developing immature stages, so adult mosquitoes already flying are not affected.[1]
