Naled / Dibrom

Naled is an insecticide that has been registered since 1959 for use in the United States. It is used primarily for controlling adult mosquitoes, but is also used on food and feed crops, and in greenhouses.  For mosquito control, naled is applied as an ultra-low volume (ULV) spray. ULV sprayers dispense very fine aerosol droplets containing small quantities of active ingredient insecticide that drift through the air and kill mosquitoes on contact. The amount that reaches the ground is small. For mosquito control, the maximum rate for ground and aerial application is very small.

When applied according to label instructions, naled can be used for public health mosquito control programs without posing risks to people. People aren’t likely to breathe or touch anything that has enough insecticide on it to harm them. Direct exposure to naled during or immediately after application should not occur. However, anyone who has a particular concern because of an existing health problem should talk to their doctor. Also, those who tend to be sensitive to chemicals in general, including household chemicals, could experience short-term effects such as skin, eye and nose irritation.
