Town of Del Norte shares mosquito spraying information

Mosquito spraying

DEL NORTE— The Town of Del Norte Public Works Department began spraying for its annual mosquito spraying operations beginning the week of June 17 and will continue each Tuesday and Thursday evening through the end of August. The Town does this to control the mosquito population and to protect the residents and visitors that visit the town.
Residents can assist Town mosquito control efforts by eliminating standing water within their yards. During operations the town uses a combination of larvicides and adulticides. Larvicides are used in public areas of standing water and the Adulticides (Evoluer 30/30) are applied through truck mounted aerial operations. These machines emit a fine spray into the air; residents should close windows and limit outside activities during operations, and please prevent children from following the truck (yes, kids do this).
This is the service that each residents of the town pays for, and as such all locations within town limits are sprayed; areas next to the river and ditches are oversaturated.
There are several facts that affect the operation— weather, wind and mosquito concentration. If conditions include rain or wind above 10 mph, this prevents the Town from continuing the spraying operations. Due to the nature of application methods, they will only spray on Tuesdays and Thursdays from 7 to 11 p.m. If the above mentioned conditions prevent spraying on these days, they will not spray again until the following week. This is done so residents can evenings knowing spraying will only be on those two days— the same two days each week.
Spraying will be reduced to one day a week, on Thursdays, when the concentration of mosquitos has declined.
In summary: Mosquito spraying will run each Tuesday and Thursday through the end of August from 7-11 p.m.
