Unfavourable Weather Slows Mosquito Control Operations
The Mosquito Research and Control Unit (MRCU) advises the public that mosquito activity has recently increased across Grand Cayman. The team is working hard to bring the numbers down as quickly as possible.
Recent weather conditions have made operations very difficult. Daytime larviciding missions, which target mosquito larvae before they hatch, were not completed before the recent heavy rainfall. As a result, more mosquitoes have emerged than usual.
To respond to the current situation, MRCU has converted its aircraft to carry out adulticiding operations – treatments that target flying adult mosquitoes. These missions are conducted shortly after sunset using both aircraft and truck foggers to help make outdoor conditions more comfortable for residents.
Weather plays a big role in mosquito control, and this year has been especially challenging. Rain, wind, and humidity all affect when and how the team can safely operate. When MRCU is able to complete larviciding missions before rain, the number of mosquitoes that emerge is much lower. However, with current mosquito levels so high, the priority has temporarily shifted to adulticiding to quickly reduce the adult population.
“Our team is doing everything possible to bring the mosquito population back down, but the weather continues to be a major factor,” said Dr Alan Wheeler, Director of the MRCU. “We ask the public to please bear with us as we continue our efforts.”
MRCU remains committed to protecting residents’ comfort and well-being, and appreciates the public’s patience and understanding as operations continue across Grand Cayman.
