The velvety tree ant originates from Central America but has spread to parts of North America over time. 

They are found throughout Southern California where they typically nest at ground level on trees or bushes near homes or buildings.

Scientific name Liometopum apiculatum, L. luctuosum and L. occidentale
Life span 6-12 months
Length 2.5-4.5 mm or 0.098-0.175 inches
Color Red-Brown/Velvety Black
Diet Sugary foods, small insects, and similar
Colony size Smaller colonies: 40-60.000 members [1]

What Are Velvety Tree Ants?

Velvety tree ants closely resemble other leafcutter or fungus-growing ants in appearance, however, they can be distinguished by their lack of hairs on the thorax and longer antennae. 

These velvety insects have large heads with small eyes which allows them to be good at digging and moving soil.

They like to infest wood, and are therefore categorized as “wood-infesting” organisms along with moisture ants and carpenter ants.

Origin of Velvety Tree Ants

The origin of velvety tree ants is in the tropics. They are most commonly encountered in the Southwest U.S. and Mexico.

The Appearance of Velvety Tree Ants

The appearance of velvety tree ants is characterized by their red-brownish/velvety-black color. Their head and body are around the same size, but they do have a larger mandible than other ant species. 

They do so because of their wood-chewing nature.

These ants look very much like carpenter ants, and are often mistaken for this species. 

A way to tell them apart is by the debris they create when chewing through wood. Velvety tree ants produce frass with a finer consistency.

Habitat of Velvety Tree Ants

Velvety tree ants are native to the forests of the Southwest U.S.. They build colonies that can number in thousands, and they will take over any space if it provides shelter or access to food sources like aphids.

Nesting Habits of Velvety Tree Ants

Velvety tree ants are known for their nesting habits. They usually nest trees such as rotting logs or tree stumps, but they can also be found under stones and other objects on the ground. 

These ants also like to nest in insulation or in wall voids in homes, much like carpenter ants.

Velvety Tree Ant Queen

The velvety tree ant queen can be identified by its large size compared to her worker counterparts. She has an orange coloration to her body and wings.

The velvety tree ant queen lays eggs that will develop into worker ants within an established colony. The workers are responsible for gathering food, expanding the nest, caring for larvae, and protecting the colony from predators.

Identification of Velvety Tree Ants

The velvety tree ant is a species of ants in the genus “Liometopum”. It belongs to the family Formicidae under order Hymenoptera which also includes wasps and bees.

They get their name from their velvety-black abdomen.

In the U.S. you will encounter three different species of velvety tree ants. As mentioned, they look very much like carpenter ants. The way to tell these two species apart is by the frass they produce when chewing through wood.

Carpenter ants produce rougher frass, where velvety tree ants will produce frass with a much finer texture.

Velvety Tree Ants Diet

Velvety tree ants are omnivores. They eat other insects, plant material, and sweet substances like nectar or honeydew secretions from aphids. 

This is much like many other ants.

While they nest in trees and chew through this to create their nests, they don’t actually eat the wood, contrary to many people’s beliefs. This goes for the carpenter ant as well.

How to Get Rid of Velvety Tree Ants

Velvety tree ants are not harmful to humans. However, they can be a nuisance because of their tendency to invade and nest in insulation and wall voids in homes and buildings. 

Velvety tree ant removal can be done by hiring a pest control expert or doing it yourself depending on the severity of infestation. 

You should inspect the severity of the problem to determine the extent of invasion before any type of treatment is started.

Use pesticides

If there are already colonies established within your home, it’s important to act quickly when trying to get rid of them. 

Be thorough when applying pesticides because they will need more than one treatment since they can be persistent little pests if left untreated for too long

If you want to tackle an infestation yourself, here’s what you can do:

  • Use ant bait to lure out the ants and kill them.
  • Use ant spray directly at the entrance points to their nest.
  • Apply ant-killer powder to infested areas and around the base of trees where they nest.

These three items are good at combating velvety tree ants, whether they’re in your home or in trees nearby.

Call an exterminator

If there’s no way you can get rid of an infestation on your own, it might be best to contact professional pest control services. They’ll have experience with exterminating these pests from homes so they will know exactly how to go about doing their job correctly.

How to Prevent Problems With Velvety Tree Ants

Velvety tree ants are very tiny, so they can enter your home without being seen. If you want to prevent an infestation, here are some things you can do.

Seal off any possible points of entrance

A good way to prevent any further infestations of velvety tree ants is by sealing off entryways into your home [3].

Keep wood away from your house

Velvety ant nests are usually found in the ground under rocks, in rotting woodpiles, tree stumps, or in firewood stacks that haven’t been kept dry enough. 

Make sure you move or store these things away from your house so that velvety tree ants aren’t tempted to infest your house. By separating tempting nesting areas from your house, you’ll divert their attention away from your home.

Conclusion

The velvety tree ants are a very interesting species of ant. They get their name from the fact that they have hairs on their bodies which give them a velvet-like texture.

They also get part of their name from the fact that they like to nest in trees. They are very similar to the carpenter ant in terms of behavior and looks.
