Aphids, also called greenflies and blackflies, are common pests in landscapes that feed on sap. Like most pests, aphids are small, making it challenging to detect signs of an infestation. Aphids are one-eighth of an inch long, which makes them invisible during the initial stages of infestation. However, delaying maintenance increases the rate of deterioration in large trees.

Spotting Aphids on Larger Trees

If you suspect a problem with your trees, contact the Sesmas Tree Service for professional help. We are a reputable tree care company with extensive industry experience and knowledge, ready to help you detect and address an aphid infestation. Here are the telltale signs of infected trees.

Sticky Leaves

The easiest way to determine if you have an aphid infestation is to see if they are sticky. As mentioned, aphids feed on sap and often suck the sap out of the leaves. This results in a sticky residue following an aphid attack, and delaying treatment can compromise the tree’s well-being. Conduct routine inspections or hire a professional tree service to diagnose and address the problem. While stick leaves might not be a significant issue, you need to act fast before it affects tree health and longevity.

Black Fungi

Black fungi are common signs of an aphid infestation in large trees. The sap from the leaves creates ideal conditions for fungal growth, compromising the well-being of your trees. Although black fungi are merely a cause for concern in the initial stages, the spores can fall on the sap and spread. The last thing you want is an infested yard, increasing the risk of an aphid infestation. If you notice black fungi growing on your tree’s leaves, it may be time to call a professional tree care company to address the problem.

Sap Below the Tree

Check below the tree, particularly around the base, to see if there’s sap. Aphids feed on the sap, which inevitably falls on the ground. Therefore, sap on the ground below a tree may suggest an aphid infestation. Sometimes sap is not noticeable on the ground, so hire a certified tree service provider for routine maintenance. We can pinpoint the slightest sign of damage and recommend long-term solutions to prevent a recurrence.

Yellow Spots

There are many causes of yellow spots on leaves, including an aphid infestation. Aphids are yellow, and a full-scale infestation resembles the tree’s yellow spots. However, not all yellow spots are caused by pests, and you should consult an arborist for diagnosis and treatment. As mentioned, an aphid infestation often goes undetected, but experts leverage extensive knowledge to detect, diagnose, and address such issues before they get out of hand.

Curled Leaves

Curled leaves are the most noticeable signs of pest damage. As these pests feed on tree sap, they chew through the foliage, causing the leaves to curl downwards or upwards with time. If your tree has curled leaves, inspect it for telltale signs of an infestation, or eliminate the uncertainty by hiring a tree service provider.

Customer Reviews

3 large Leyland Cypress trees removed near front of our home. Excellent service, professional crew, very competitive pricing for superior work! Rolando provided the initial estimate and the  follow up and was the best in terms of customer relations. I'd both use this company again AND highly recommend them.

Susan Hitchcock

This is the 2nd time we have used Sesmas Tree Service. They are a wonderful company to deal with. They were on time, professional, and very thorough. They cleaned up prior to leaving and went out of their way to protect our plants and landscaping. And they kept to their proposal with no hidden cost or add ons. Definitely a five star experience!

Gene McFadden

Wow!  I deal with tree services in my professional work and I can honestly say Sesmas is by far the most professional, best equipped, efficient, safety conscious, and communicative service I've ever encountered.  Their price was very reasonable and they even went so far as to include additional work without increasing the price.  Call them!  Now! They are very quick to respond.

Scott McLendon

We've used Sesmas several times and have always received excellent service.  Estimates are quick and easy and the crew is efficient and leaves the property clean of debris.  Recently we needed a tree removed next to a heavily landscaped area.  Sebastian went over everything with me in detail and listened to my concerns.  The crew did an excellent job in removing the tree with minimal disturbance to the surrounding area.  We are pleased and will consider them again in the future for pruning and tree removal.

Tonia Griswold

Sesmas Tree Service was amazing! I had two dead trees cut and a lot of trees that were already down on my property removed. Sebastian came out and sent the quote in writing within 24 hours. We were in the process of scheduling the service when a slot opened up sooner snd I was able to go ahead and get the work done. Everything was explained ahead of time for what to expect. The crew was very efficient and professional.  All of the work and cleanup was done in one day. I would recommend Sesmas for your tree cutting/cleanup needs.

LaDora Woods

I hired Sesmas to cut down a very tricky tree that was hanging over my house as well as a few large limbs. They did a great job and had the machinery to get the job done right.

Perry Hartman

Great experience with Sesmas. They were meticulous with my tree removal, safe and efficient. David’s communication throughout the process was much appreciated. Highly recommend!

Lindsay Ellenburg

Great experience with Sesmas Tree Service. The arborist who came out was a Board Certified Master Arborist, and you could immediately tell he knew his stuff. He took the time to explain what needed to be done, gave us clear options, and helped us feel confident from start to finish. The whole process was easy and professional. We’ll definitely use them again.
