Identifying Mantis Eggs on Christmas Trees

• Foamy Sacs: Mantis eggs are encased in foamy, Styrofoam-like sacs known as oothecae.

These brown sacs are often attached to branches.

• Small, Oblong Shapes: Look for small, oval shapes about the size of a thumbnail, which can blend into the tree’s needles.
• Natural Camouflage: Mantis egg cases are great at blending in with the tree's texture, with their brown color and foamy feel mimicking bark or needles.
• Attached to Twigs: These egg cases are usually firmly attached to twigs or branches, chosen for their secure support.
• Subtle Appearance: Mantis eggs don’t stand out; they’re discreetly nestled within the tree, waiting to be found.

How to Handle Mantis Eggs on Christmas Trees

• Understand Their Habitat: It’s not unusual for mantises to lay eggs on Christmas trees. These trees offer mantises protection from winter and predators, making them a popular choice for egg-laying. To keep them from spreading indoors, it’s best to remove mantis egg cases promptly.
• Inspect Before Bringing Inside: Carefully examine your Christmas tree for any signs of mantis egg sacs (oothecae) or other insects before setting it up indoors. This is the best way to prevent mantis eggs from hatching inside due to indoor warmth.
• Remove Egg Cases Gently: If you spot an ootheca on your tree, cut off the branch with the mantis egg case and place it outside. Moving it to a nearby tree or shrub allows the eggs to hibernate safely and hatch in the spring.
• Consider Garden Benefits: Mantis eggs are harmless to humans and can actually benefit your garden by feeding on other pests, helping to keep insect populations in check.
• Dispose Carefully if Needed: If removing the ootheca isn’t possible, either place the entire tree outside after the holiday or dispose of it in a sealed bag. Sweep or vacuum up any nymphs that may have hatched and crawled from the egg case.

FAQS

Are Mantis Eggs Harmful?

No, mantis eggs are harmless to humans and pets. In fact, they’re helpful since mantises feed on common garden pests like aphids, acting as natural pest controllers.

Why Do Christmas Trees Attract Pests?

Indoor warmth can make mantises think it’s spring, prompting the eggs to hatch. This can be an issue, as each egg sac may contain up to 200 eggs, leading to a sudden increase in tiny mantises.

Can Mantis Eggs Be Found on Fruits and Vegetables?

It’s rare to find mantis eggs on fruits or vegetables, as mantises usually attach their egg sacs (oothecae) to twigs, branches, or stems in sheltered areas.

If found on produce, the egg case likely ended up there during harvesting or packaging, as mantis egg cases are most often found outdoors.
