There may be an up side to the cold winter St. Louis area residents are enduring this year. Entomologist Chris Hartley tells Fox 2 News the extreme cold now could mean fewer insect pests come spring.
Hartley works at the Missouri Botanical Garden's Sophia M. Sachs Butterfly House at Faust Park. He says some species of flies and ticks have moved north into Missouri because of the mild winters over the past several years.
"By creeping north like that, they're entering ranges where they normally wouldn't have been," Hartley said. "And they are susceptible to maybe getting froze (sic) back some."
Hartley says the deep freeze won't affect the mosquito population, since those pests hibernate.
He also says it may not be quite cold enough to put a dent in the population of the Emerald Ash Borer, like it probably has in Minnesota. But, Hartley says, we won't know until spring.
