Ladybug swarms have been reported recently in Tennessee, North Carolina, and Maryland, among other states, as the insects have been invading houses and other structures as they search for a warm place to stay over winter.

Their populations are also high this year due to abundant food sources, so in some cases these cute little insects are temporarily considered household pests.

“The ladybugs come from the north, over here, and it looked a swarm of hornets coming,” reported one home owner from Tennessee to USA Today. “About 12 o’clock noon, they covered the whole side of this house from that side, all the way around.”

The following videos show ladybugs invading a house and a barn:
