The Mosquito Research and Control Unit said it’s working overtime to fight the mosquito that carries the Zika virus while simultaneously handling its nuisance control duties.
The MRCU said its crews have been working flat-out to treat vulnerable areas like preschools against the aedis aegypti mosquito. As well as conducting thermal fogging operations by-request at the homes and workplaces of pregnant women.
This, in addition to carrying out control operations against the swamp mosquito, which isn’t a public health risk, but due to weather patterns has presented a formidable nuisance this season.
“The swamp mosquito is more active at night after sunset and also before sunrise, so when the MRCU sprays, they take that into account, and when they spray at night and you see the plane spraying after sunset, that’s targeting the swamp mosquito and it doesn’t have an effect on the aedis aegypti,” said Oxitec Operations Manager Renaud LaCroix.
The differing habits of the two species make it possible for the MRCU to spray for the swamp mosquito without affecting the so-called ‘friendly’ aedis aegypti project.
