CENTRAL POINT, Ore. — After tracking West Nile in Jackson County, Vector Control biologists want you to protect your property’s water from mosquitoes. Sitting water in troughs or ornamental ponds can be a place where mosquitoes like to hang out. They are either born there, or returning to lay larvae creating the next generation.
So, Jim Lunders, Manager and Biologist at Jackson County Vector Control in Central Point recommends getting mosquitofish (Gambusia affinis) to get rid of them. These fish are related to guppies and get grow up to two inches long. They feed on the top of the water column where larvae are active.
“If there’s things in your backyard that you can get rid of that’s a permanent solution you don’t have to worry about. But some things, you know, livestock watering troughs, things like that, they need to hold water all the time and these are really a good solution you can control the mosquitoes in those without having to use pesticides,” said Lunders.
Jackson County Vector Control gives away mosquitofish for free. Other options for mosquito control in water is to buy products containing Bacillus thuringiensis israelensis (BTI) or methoprene.
