Enjoy a fragrant evergreen indoors without unwelcome hitchhikers.

Nothing brings the holiday spirit into your home quite like a real Christmas tree. The scent of pine, the natural beauty, and the tradition of decorating together all remind us of the joys of the season. But live evergreens can also bring some unwanted guests into your home: bugs and insects that have been hibernating deep within the tree’s branches and bark.

Understanding which pests to watch for and learning how to properly prep and manage your Christmas tree will ensure your family enjoys a festive, bug-free holiday.

Common Bugs Found in Christmas Trees

Most Christmas trees, especially freshly cut ones, host a variety of small insects. While these bugs are rarely dangerous to humans, they can become a nuisance and, in some cases, invade other houseplants.

Adelgids: Small, woolly insects that look like a dusting of snow.
Aphids: Tiny, sap-sucking bugs, often mistaken for ticks. Typically found on lower branches.
Bark Beetles: Small, reddish-brown insects that burrow into bark. Can leave small holes and sawdust-like residue.
Mites: Usually red or brown, favoring tree sap. Spruce spider mites are a common holiday pest.
Scale Insects: Hard-shelled, orange or red bugs that feed on sap. Leave sticky residue on branches.
Praying Mantises: Mantid egg cases may hatch inside, releasing many tiny mantids.
Psocids (Bark Lice): Harmless, soft-bodied insects attracted to mold and decaying matter on trees.
Spiders: Seek shelter in dense needles, where they hunt for other insects.
Moths and Sawflies: Can lay eggs that might hatch indoors due to slightly warmer temps.
Weevils: Small beetles that may dwell in the bark or needles.
Webworms: Caterpillars that can build nests or webs among the branches.

Of these, aphids, mites, and scale insects are the most common and likely to be noticed on trees brought indoors.

How Do Bugs Get Into Your Christmas Tree?

Bugs commonly overwinter as eggs or larvae in tree bark and branches, remaining dormant in the cold outdoor environment. Bringing your tree indoors mimics the arrival of spring, prompting these insects to wake up and become more active. The warm, cozy environment encourages them to move out of hiding, sometimes seeking food or new shelter elsewhere in your home.

Signs of Bugs in Your Christmas Tree

Most Christmas tree bugs are small, but there are signs to watch for:

Tiny moving dots on branches, needles, or trunk.
Clusters of eggs (small, round, and often stuck to the underside of needles).
Fine webbing, especially near branch tips (indicates spider or webworm presence).
Sticky residue on needles or ornaments (from sap-sucking insects like aphids or scale).
Small holes in the bark or sawdust at the base (potential bark beetle activity).
Brown patches or dead needles, which can indicate heavy pest presence.

Types of Trees Most Affected

The type of bugs you might encounter often depends on the tree species and where it was harvested:

Norwegian Pines are notorious for carrying the most bugs.
Balsam Firs attract aphids and mites.
Douglas Firs, Scotch Pines, and Norway Spruce often host mites and scale insects.
White Pines commonly attract spruce spider mites and aphids.
Fraser Firs may contain a variety of aphids and mites.

Are Christmas Tree Bugs Dangerous?

Most bugs found on Christmas trees are harmless to humans and pets—they don’t bite, sting, or transmit diseases. However, some may cause mild allergic reactions or become a nuisance if they spread to other plants. Aphids and mites, for instance, can infest other houseplants if not addressed. On rare occasions, larger hatches like praying mantis egg cases can become a surprising, if harmless, indoor event.

How to Prevent Christmas Tree Bugs

Preventing pests from hitchhiking into your home with your Christmas tree is easier when you take a few practical steps. The earlier you start, the less likely you’ll have to deal with pests after the tree is inside.

Inspect Before Buying

Look for obvious signs of insects or egg masses on the trunk or under branches.
Use a flashlight to check the dense inner branches.
Avoid trees with thick clusters of white specs (adelgids) or sticky sap (a sign of sap-feeding pests).

Shake the Tree Thoroughly

Most tree lots have a mechanical shaker—ask if you can use it before purchasing.
If not, lift the tree several inches off the ground and drop it sharply to dislodge loose bugs and eggs.
Repeat a few times. This also loosens excess needles for easier clean-up.

Let It Sit Before Decorating

Place your tree in a garage or enclosed porch for at least 24 hours before bringing it inside. This helps dormant pests emerge in a contained area.
Use this time to further inspect and treat the tree if needed.

Clean Up Regularly

Vacuum around the tree base and disposal area daily to pick up fallen insects, needles, and debris.
Shake out stockings or soft decorations periodically in case insects have moved.

Pre-Treat the Tree (Optional)

Dust with diatomaceous earth (food-grade, natural powder that kills crawling insects). Shake off excess before indoor use.
For persistent issues, spray with neem oil (OMRI Listed^®) on branches and trunk, especially for visible pests at all life stages.
Never use chemical insecticides indoors, as these can be toxic to people and pets.

Professional Pest Control

For severe infestations, consult a pest management professional experienced in eco-friendly solutions.
Many pest control services offer integrated pest management (IPM) for both prevention and quick removal.

How to Get Rid of Bugs if You Find Them

Even after careful inspection, some bugs may make it indoors. Here’s how to eliminate them quickly and effectively:

Vacuum all visible insects and eggs from branches, trunk, and nearby floor. Dispose of the vacuum bag promptly.
Sticky traps placed near the base trap wandering bugs, such as spiders or aphids.
Diatomaceous earth can be sprinkled at the base if infestations persist.
Manual removal of egg clusters (gently scrape off or snip affected twigs).
If you notice large numbers of bugs, return the tree to the vendor (most reputable retailers will exchange trees if infestation is severe).
For particularly persistent pests, set up an indoor fly trap (using UV light and sticky pads).

What Not to Do: Safety Tips

Never use chemical aerosols, foggers, or bug sprays on live Christmas trees indoors. They can be fire hazards and pose health risks to family and pets.
Do not burn infested branches in your fireplace. Some pests produce chemicals or odors that are hazardous when burned indoors.
Avoid overwatering, as excess moisture can encourage new pest problems beyond those that came with the tree.

Are Artificial Trees Safe from Bugs?

Artificial trees are generally less likely to harbor insect pests. However, they can still collect dust, cobwebs, or occasional bugs from storage areas. Always inspect and clean artificial trees prior to assembly—especially if stored in basements, garages, or attics.

Natural Pest Remedies and Preventative Products

Diatomaceous earth: Natural powder, effective and safe for kids and pets, applied before bringing the tree inside.
Neem oil spray: Treats eggs and developing insects, best applied in a well-ventilated area outdoors.
Eco-friendly professional pest control: Integrated Pest Management approaches tackle persistent issues safely.
Mechanical shakers, vacuuming, and manual removal: Non-toxic, safe methods that are usually effective when done promptly.
