Welcome to Capital Arborists: Orangevale’s Professional Eco-Friendly Solution to Aphid Suppression
At Capital Arborists, we understand the vital role trees and shrubs play in the beauty and ecological balance of the Orangevale area.
When aphids invade, the health and beauty of your trees is threatened. Aphids leave behind sticky sap, leaving you with sticky trees, sticky cars, sticky patios, and a headache. Aphids aren’t just annoying – they also suck nutrients from trees and can wreck the health and beauty of your prized roses, Crape Myrtles, Oaks, and other trees. Left unchecked, you’ll have a mess!
That’s where we come in. Our dedicated team of Orangevale ISA Certified Arborists specializes in treating trees and shrubs to effectively combat aphid infestations while adhering to the most environmentally sound practices.
Our approach to aphid suppression is rooted entirely in sustainability and the well-being of your landscape. We employ cutting-edge science and innovative techniques to target aphids without disrupting the delicate ecological equilibrium of your trees and garden.
Our plant health care team aren’t just technicians – they’re ISA Certified Arborists, each with long careers in exactly this – treating Orangevale trees for aphids and other pests and diseases. You have true professionals on your property, able to answer questions, spot issues, and aid your trees with exactly what they need.
Why choose Capital Arborists for aphid suppression?
We practice not just treating to suppress aphids but in growing a healthy, thriving environment where trees and shrubs can resist pests naturally. Our team of plant health care professionals and ISA Certified Arborists has decades of experience working with trees, tree diseases, and tree pests – all gained right here in the Orangevale area. We know Orangevale trees, and we know how to efficiently and effectively suppress aphids!
We never use broad-spectrum insecticides to suppress aphids! What is a broad-spectrum? These are ‘old school’ pesticides that are known to wreak havoc on landscapes. Broad spectrums are just what they sound like – they’ll kill everything they touch, including beneficial bugs and insects that naturally reduce major tree pest infestations. Harming beneficial insects is not our style, nor what’s best for your landscape! Here at Capital Arborists, we take a different approach – instead, injecting the soil with a product that only suppresses the aphids. Never harming the ‘good guys’ of your garden!

What is the stickiness from the tree?
The sticky substance from an aphid infestation is their waste. Yep, it’s aphid poop! Aphids feed on the tree and leave sugar behind in the form of sticky honeydew. While it’s not in itself hazardous to humans or pets, it does leave a huge mess and often leads to other sugar seeking insects moving in, like ants, cockroaches, and scale.
Do aphids harm trees?
Yes! Beyond the mess they leave behind, we suppress aphid infestations because aphids are sucking insects. They move in onto leaves and stems and suck the nutrients, water, and vigor out of the tree or shrub. Small amounts of aphids are a normal part of any backyard ecosystem and serve as food for beneficials, but infestations that cause that noticeable amount of sap and stickiness are signs your tree could be in trouble and the aphids should be suppressed.
Are there trees more susceptible to aphids?
There are trees most susceptible to aphids! All trees can get them, but aphids particularly love roses, Crape Myrtles, Oaks, and Maples.
How do I know I have an aphid problem?
Aphids are little insects that usually appear as green, orange, or purple. Most often found on the underside of leaves, or on leaf stems (sometimes on branches as well if there are a lot of them!). Most of our clients will notice the mess they leave first, though! Sticky clear dots all over your windshield, patio, furniture, or plants below an infested tree are a pretty good tell for aphids having moved in. Our ISA Certified Arborists will stop by and confirm the diagnosis before we set up any treatments to make sure it’ll be effective!
How do you treat for aphids?
We perform what is called a Merit Systemic Treatment. It’s an injection into the soil that is absorbed with water through the vascular system of the tree, and goes into the leaves and tissues. As an aphid sucks from that leaf or tissue, they get a dose of the treatment and suppression as a whole begins!
Will I get total control with this treatment? Will all of the aphids be gone?
We subscribe to suppression is best. Your infestation and sappy sticky mess should be mitigated, but occasional aphids may return as part of a healthier ecosystem. You likely won’t notice or have trouble from them!
Is this a one time thing?
While we can do a one time treatment, aphids will need to be suppressed at once or twice per year (depending on your trees!) for sustainable results.
Can I get this product myself?
Nope! While it used to be available over the counter in less concentrated formulas, environmental protections in California have changed and it’s only available to professionals with proper licensing and professional training to apply the treatment to trees. This license is called a Qualified Applicator’s License from the California DPR, and you can meet our plant health care professionals here!
Who is going to come out to inject my soil for this?
One of our licensed plant health care professionals! They’re a highly knowledgeable team of arborists and can answer any tree or aphid questions you’ve got while they’re out!
Does this harm beneficial insects?
It does not, and that’s why we use this specific method! The merit treatment is efficient, tree safe, and safe for pets, humans, and beneficials.
How much does aphid suppression cost?
It depends on how much of the product and time we’ll need to treat the soil, and that depends on a few factors, like the tree’s size, location, and if other trees and shrubs will be treated as well while we’re out. Our estimates are complimentary, and our ISA Certified Arborists would love to come meet with you, take a look at your trees, answer any questions, and get you an estimate for handling aphids if need be.

Reviews from Orangevale, CA
“We have many majestic Oak trees that are a major feature of our property. So, when it comes for caring for these trees, we want excellence. When our former trusted arborist left the area, we asked him for a recommendation. Without hesitating, he recommended Mike as Capital Arborists. We are glad we took his advice. Capital Arborists has excellent equipment including modern lifts needed for working on our trees. Our crew was on time, professional, worked very efficiently and kept our property spotless before leaving for the day each of the days they were here. They were also extremely pleasant people to have around. We strongly recommend them for tree care and will be having them back.”
