Orange galls, fuzzy galls or fuzzy orange galls, no matter what you call them if you have an oak tree in your yard or on your property you likely have them. The culprit is the Cynipid wasp, a tiny member of the Vespidae family that lays its eggs on oak tree leaves.
How do you treat oak gall?
Oak Gall Management
- Prune and destroy gall-infested twigs and branches.
- Burn or step on the galls to kill the developing larvae.
- Place gall remains in a tightly sealed baggie or trash bag and discard immediately.
- Rake and destroy gall-infested fallen leaves.
Should I remove oak galls?
Something you can do now – and I heartily recommend it – is to remove and destroy any galls you can find on the trees. There probably are many on twigs and branches; look for knobby and hard growth. Chances are it’s a gall. By removing it now, you lessen the number of eggs available to hatch come spring.
What are the round balls that grow on oak trees?
When looking at an oak tree with small round balls hanging on the branches, you may have noticed it, much like acorns. These balls are known as galls and are not actually fruits. Galls are caused by parasitic insects and are actually growths. There are many species of gall wasps in North America that need oak trees.
What tree produces fuzzy balls?
Trees With Spiked Seed Pods. If you’ve encountered some round, spiny balls under a tree or maybe still on the plant, and you’re wondering what it could be, it’s likely one of several options: buckeye/horsechestnut (Aesculus), chestnut (Castanea), or sweet gum (Liquidambar styraciflua).
What are oak gall wasps?
Gall wasps are small, brown wasps with the abdomen flattened side to side. Many gall wasps develop for 2 or 3 years in woody galls on the twigs of oaks. Adults then emerge from the twig galls during the winter. They lay eggs in the buds and die.
What does a diseased oak tree look like?
Conks are initially white or light-colored and turn black and crusty with age. Infected trees show symptoms of general tree decline including branch dieback, loss of leaves and yellowing or browning of leaves in summer. Trees weakened by drought stress, wounding or other injuries are most susceptible.
Are oak tree galls poisonous?

Are oak galls harmful to dogs?
Not only are they a choking hazard, but oak acorns and young oak leaves also contain a chemical called gallotannin, which can cause severe gastrointestinal distress in dogs, including vomiting, lethargy, diarrhea, and damage to the liver and kidneys.
Do squirrels eat oak galls?
The first are tiny wasps that cause a growth, known as a gall, to form on twigs and small branches of oak trees. The second offender are squirrels, who think the galls make a tasty snack. Eventually, Tynan said, galls can grow big enough to choke off nutrients to the oak leaves.
Do birds eat oak galls?
Many oak galls are subject to foraging by birds such as scrub jays, nuthatches, titmice, sapsuckers, and many others. These birds drill into galls in search of wasp larvae. Woodrats are even known to store galls before later eating them whole!
How do you get rid of leaf galls?
Before you ever see bumps on leaves or other plant parts, spray with a miticide to prevent galls on ornamental plants. Horticultural oils and some insecticides will be effective but not after the mites are under the surface of the plant.
What are the balls on a sycamore tree?
They are spiked balls that are produced by Sycamore trees and contain the seeds that can be used to start new trees. They are produced in the winter and can be found all over the ground around the trees in the spring. One of the most popular uses for these balls is making ornaments for the holidays.
What are the large growths on oak trees?
When you look up into the bare branches of some oak trees at this time of year, you can see ball-shaped growths hanging there, looking almost like nature’s Christmas ornaments. These are galls. A gall is an abnormal growth produced by a plant under the influence of another organism.
