Santa may be sneaking down your chimney, but he’s not the only one making his way into your home. An avalanche of bugs is likely riding the Christmas Tree Express straight into your living room, reports the AFP. It spoke to a scientist who cited research that has found as many as 25,000 insects—ranging from bark lice to moths to mites—living in a single tree. The lights and heat spur them to come out of hibernation, but don’t fear a creepy, crawly bug invasion: “As they cannot feed on the limited plants found in most households, the bugs will quickly dry out and die,” says the scientist.
