Altosid XR Briquets make application easier and still deliver season-long control of mosquito larvae for up to 150 days.


Altosid XR Briquets are specially designed to effectively control and prevent adult mosquito emergence in treated areas. It is just like Altosid 30 - Day Briquets, which require no expensive application equipment and can be pre-treated before wet season starts. That means you're better able to treat hard-to-access or out-lying areas, and can eliminate the additional costs associated with travel and multiple re-treatments.

Altosid XR Briquets work by releasing effective levels of (S)-Methoprene insect growth regulator for up to 150 days in mosquito breeding sites. This will allow larve to grow to adult mosquitoes and then die. However, it will not work with mosquitoes that are adults before treatment. It is advisable to be applied before the start of mosquito season or wet season. This allows for better coverage. 

Altosid XR Briquets prevent the emergence of adult mosquitoes including: Anopheles, Culex, Culiseta, Coquillettidia, and Mansonia spp., as well as those of the floodwater mosquito complex (Aedes, Ochlerotatus, and Psorophora spp.) from treated water.  treated larvae continue to develop normally to the pupal stage where they die.
