Japanese beetle infestations are not likely to be hindered during the cold weather temperatures, according to Donald Lewis, professor of entomology at Iowa State University. The beetles have adapted to winters and are likely to thrive once spring and summer arrive.

The Japanese beetle infestation began in 1926, when they were first discovered in New Jersey. Since their discovery they have been found in every state east of Mississippi. In Japan they are not considered a pest, because their natural predators control the population.
