Will a cut Christmas tree bring bugs into my house or cabin?

Short answer

Sometimes, but they're harmless. A fresh cut tree can carry aphids, tiny spiders, mites, adelgids or a praying mantis egg case that wake up in a warm house. Iowa State University Extension says they can't bite or sting, won't harm the tree, your home or your family, and die quickly indoors. Shake and check the tree before it comes in, vacuum up strays, and never spray the tree.

Arizona context

Christmas tree permits for the Apache-Sitgreaves National Forests are available from November 1 to December 31, so many White Mountains families cut their own tree in the forest. A tree cut in the woods hasn't been through a tree lot's mechanical shaker, so shaking and checking it yourself matters more. University of Illinois Extension says these pests are rare, showing up in about 1 out of 100,000 cut trees, and most of them stay on the tree.

What you can do

Before you load it up, tap the trunk on the ground several times or shake it hard to knock off loose needles and insects.
With the tree on its side, look into the branches from the cut end. Cut off any branch with a praying mantis egg case and leave it outside in an evergreen, and remove any bird nests.
Vacuum up any insects or spiders that wander onto floors, walls or windows.
Never spray the tree. Aerosol insect sprays are flammable and are not labeled for use on Christmas trees.

When professional service is warranted

If bugs keep showing up after the tree is gone, they probably aren't from the tree. Spiders, cluster flies and other pests that winter inside walls are common in White Mountains cabins, and that's worth a closer look.

How Hydra handles it

Bugs from a Christmas tree don't need pest control. If you're still seeing spiders, flies or other pests after the holidays, talk to an Office Pro. Our Service Pros can find where they're getting in and set up exterior prevention for your home or cabin. Ask for a free custom quote.

Frequently asked

What bugs live on Christmas trees?

University of Illinois Extension lists adelgids, aphids, predatory mites and praying mantis egg cases as the most common. Iowa State University Extension says aphids and spiders are the two pests most often found. Other small insects can also ride in.

Will Christmas tree bugs infest my house?

No. Iowa State University Extension says they won't live long enough to grow or multiply indoors. They die quickly from starvation or drying out.

Should I spray my Christmas tree for bugs?

No. Iowa State University Extension says spraying a fresh cut tree isn't necessary or recommended, and University of Illinois Extension says aerosol insect sprays are flammable and should never be used on a Christmas tree. Vacuum up strays instead.

What do I do with a praying mantis egg case on my tree?

Cut off the branch it's on and put it outside in an evergreen or another sheltered spot. If it hatches indoors, the young mantises will starve. Outside, it can hatch in spring.
