Because ponds can be breeding grounds for mosquitoes, preventing larvae from emerging from them is an essential part of a mosquito control program. Insect growth regulators (IGRs), such as Altosid® Briquets, Altosid® Liquid Larvicide Mosquito Growth Regulator and Altosid® Pro-G Insect Growth Regulator, prevent larvae from developing into breeding, biting adults. Each Altosid® product offers a different application method. Altosid® Briquets and Altosid® Pro-G Insect Growth Regulator can be used for pre-treatment before the wet season; applications should be continued throughout the season for ultimate control.
