Warm winter causes spike in island's invasive rodent population.
KODIAK, Alaska (AP) A pest control technician in Kodiak says this year's warm winter has caused a spike in the number of rats on the island.
KMXT-FM reports that BJ Johnson with American Pest Management says rat populations have surged throughout Kodiak Island this year following a third straight winter of warmer-than-normal temperatures.
Johnson says the rat being seen around Kodiak is the Norway rat, which state biologist Steve Ebbert called the most successful of the invasive rats.
Large numbers of rats are a concern because they eat eggs and chicks, which can negatively impact seabird populations.
Johnson says the solution to the island's rat problem is not a quick fix, but people can help by clearing the base of their homes of excess debris.
