» Posted by on May 4, 2020 in Tree Service | 0 comments

When it comes to landscapes and gardens, there’s one thing that is too common. These are aphids. These pests, also known as black flies and greenflies, feast on the sap of trees. However, they sometimes go unnoticed because of their small size. Aphids are only around 1/8 to 1 inch long when they completely grow.  

Though you cannot easily notice them whenever you’re far away, there are other ways to tell if your trees are infested with aphids. 

Today, we’re going to share with you a couple of tips in spotting aphids in big trees. If you see one of the signs below, you should contact a professional tree service Shreveport right away. 

Galls 

One of the things you can do is to check your tree in your lawn to see if it has galls. Aphids lay eggs, just like any other pests in the garden. That’s why they reproduce. The tree might respond by generating huge growths when aphids lay eggs on or inside a tree. These growths are also known as galls. Usually, the galls are not harmful. However, they are an indication that something is infesting your tree. 

Curled Leaves 

This is probably one of the most common indications of an aphid infestation. The leaves in your tree might curl if it is infested with aphid.  

Usually, aphids chew through its leaves as they feast on the sap of a tree. This might cause the leaves to curl downward or upward over time. 

Yellow Spots 

Another sign that your tree is infested with aphids is the presence of yellow spots on the leaves of a tree. Almost every aphid is yellow. Thus, you will notice them as yellow spots whenever they infest a tree. You might even see them moving if you view them up close. Regardless, there is a high possibility that your tree is suffering from an aphid infestation if you see groups of yellow spots on the leaves of a tree. 

Sap Below the Tree 

You’ve got to examine around the tree’s base to see if there is a sap present. This is especially true when it comes to the spot directly below the canopy. 

Sap will fall inevitable to the ground when aphids feast on it. thus, the presence of a sap below a tree might indicate that your tree is infested with aphids.  

Black Fungi 

The presence of black fungi is another potential indication of an aphid infestation in big trees. Saps promote the growth of black fungi as it sits on the leaves of the tree. Fungal spores in the air will stick on the sap. Because of this, the fungi will start to grow on the sap. 

Sticky Leaves 

You should look at the leaves to see if they’re sticky if you think that aphids have infested a big tree in your lawn.  

As we’ve mentioned earlier, small pests feast on sap. They will suck the sap out of the leaves. During this process, the aphids will leave behind a sticky residue in their wake.
