(Lander, Wyo.) – The City of Lander’s Weed & Pest Department is expected to begin mosquito spraying this Wednesday, July 2.

Lander Weed & Pest Supervisor James DeMasi said that spraying will be once a week through the summer, almost always on Wednesdays. The threshold for spraying depends on the number of mosquitos seen in traps throughout town, and that threshold was nearly met last week, he said. Traps will be checked again tonight.

The weather has been cool enough so far this year, DeMasi said, that the population of West Nile Virus-carrying culex tarsalis mosquitoes have been kept to a minimum. However with the amount of moisture seen so far, along with expected rising temperatures, DeMasi said residents should expect rising numbers of all mosquitoes in the coming weeks.

As of last Thursday, none of the culex tarsalis caught throughout the county have tested positive for West Nile Virus.

At this point the city will no spray in front of certain properties should the residents not want it during the nuisance spray period. To request no spraying, forms to fill out are available at Lander City Hall. In order to ensure no spraying happens near your property this week, request forms should be turned in to City Hall by 4 p.m. on Wednesday.

Later in the summer, should culex tarsalis reach certain thresholds, spraying could become mandatory citywide. Call DeMasi at 332-6408 with questions about Mosquito spraying.
