The Creepy Crawlies That Could Be Hiding In Your Christmas Tree

Yesterday, we talked about whether Illinois prefers real trees or artificial trees at holiday time, but today we're getting into what uninvited creatures could be crawling out of your real Christmas tree this holiday season.

I'm not saying that artificial trees are better, but I am pointing out that your chances of an insect infestation coming from your fake Christmas tree are somewhere between slim and none.

There’s no argument that there's something magical about bringing a real Christmas tree into your home. You've got the smell of pine, the glow of the lights, the ornaments full of memories…and potentially, a few uninvited guests hitching a ride inside from the great outdoors.

Before you bug-haters swear off real trees forever, let’s get something out of the way right up front. Yes, insects can be in real (sometimes called "live") Christmas trees, but it’s rarely a big deal. Still, the idea of something crawling out of your tree while you’re watching holiday movies is enough to make anyone squirm.

What Kind Of Bugs And/Or Creepy Crawlies Are We Talking About Here?

According to university extension offices across the Midwest, live Christmas trees can occasionally shelter insects that were already living there long before the tree was cut down for the holidays.

The most common ones include aphids, mites, spiders, bark beetles, and occasionally ants. And then there’s the one that really gets people’s attention: praying mantis egg cases, which can hold dozens of baby mantises.

Here’s the thing, these insects aren’t moving into your house because they want to. They’re just along for the ride. Most are dormant or barely alive after weeks in cold outdoor temperatures. When the tree is brought inside, the warmth can wake them up briefly, making it seem like your tree has come alive.

How Do You Know If Your Tree Has Insect Visitors?

If you notice tiny bugs, the most common sign is sticky residue on the tree or floor, which usually points to aphids. Spiders may crawl out looking for a quiet corner, and bark beetles might appear sluggish and confused. The good news? They’re harmless to people, pets, furniture, and your home. They also don’t reproduce indoors.

If you want to reduce the chances of a creepy surprise, give your tree a good shake outside before bringing it in. Some people also leave the tree in a garage or enclosed porch for a day or two, letting insects emerge before the tree takes center stage in the living room. Avoid spraying insecticides because those chemicals don’t belong on something you’re putting inside your home.

If a bug does appear, a vacuum or relocating the bugs outdoors takes care of the problem quickly.
