Researchers say that there are thousands of bugs in Christmas trees.
In fact, there could be as many as 25,000 bugs in an average tree.
Researchers say the bugs are not dangerous and very small. They suggest checking for eggs on trees before choosing one to take home.
Also, you may want to leave it in a garage for a few days before taking it inside.
Las Vegas Fire & Rescue shared several Christmas tree safety tips on their Facebook page recently.
They suggest picking a tree with fresh needles, not placing trees near a heat source, daily watering and turning off lights when not at home or asleep.
