What Are Spider Mites Doing on My Cedar Trees?!

Tiny Cedar Mites Can Cause Big Problems

Though not actually spiders, spider mites on cedar trees can cause damage on your cedar, juniper and cypress plants.

If you’re a gardener, you may already be familiar with garden mites that damage plants like tomatoes. Unfortunately, cedar mites and other tree mites can be harmful to your trees as well.

Oligonychus ununguis, or spruce mites, are found on spruces, pines, and other conifers.

Birch mites, Eotetranychus uncatus, affect birch species.

Spider mites can cause damage to cedar, juniper and cypress plants. Mites suck chlorophyll from the leaves, leaving the plant discoloured and branches to die off.

What Do Spider Mites Look Like?

Unfortunately for you, mites are so small they’re difficult for most people to see. A small number of mites won’t cause visible damage to your plant, but if the infestation spreads, you’ll start to notice issues with your cedars or other tree. They may look like dust if there are many mites on your plant.

You can check for mites by holding a piece of paper under a damaged branch and shaking it. If specks fall onto the paper, wait a few minutes. If those specks begin moving, you probably have a cedar mite infestation.

Mites can’t fly, but wind can carry them onto nearby plants and trees. This also means they easily fall off of plants from rain. But in hot, dry summer weather, their numbers can quickly expand.

Spruce mites, however, reproduce faster in cool weather, so can be found more in spring and fall.

How Do Cedar Mites Attack Trees?

Spider mites poke tiny holes in stems or leaves to suck out sap, or chlorophyll. Eventually, you’ll begin to notice yellow spots on the leaves, or further discolouration, curling branches, or branches turning bronze.

In widespread infestations, webs will be visible on branches, which will start to die and fall off. Spider mites can be fatal in especially bad infestations.

If your trees were infected last year with mites, the mites will wait until warm weather arrives to hatch. That’s why it’s necessary to treat cedar mite infestations to keep them from recurring the next season.

Cedar Mite Treatment

Since water can remove cedar mites so easily, just spraying your plant with a hose can help remove mites. Don’t overdo it, though — excessively wet conditions may make your plant more susceptible. It may be helpful to prune off damaged stems and branches.

We can treat cedar mite infestations and spruce mite infestations with insecticidal soap. Using dormant oil on plants in the springtime can help prevent infestations over the summer, or spraying in the fall to keep mites from nesting over the winter.

We can treat mites with natural insecticidal treatments and ensure your soil is properly balanced to prevent reinfection.

We can also use natural predators of mites, including ladybugs, lacewings, and predatory mites, for effective biological control of spider mites.

Our arborists are experts in plant healthcare. We can recommend effective treatment based on the scale of infection in your trees and ensure appropriate products are used. If you’re ready to say goodbye to cedar mites on your trees, give Vista Tree a call today!

Vista is an excellent company to deal with. The owners went above and beyond expectations to help deal with a unique situation. The guys who did the work were not only professional but also very polite. I will be using them again to help with other work in the future.

We are very happy with all the work Vista Tree Management accomplished on our property.  James was very professional and gave us excellent advice concerning the trimming of our 12 foot cedar hedges and the pruning of our mature silver maple trees.  The crew was very friendly and hard working, they did a tremendous job on the work required and they did an excellent job with the clean up.  We would highly recommend Vista Tree services to our family and friends.  We will definitely use them again for all of our future projects.

They just did my front lawn, and boy, did they leave a lasting impression!

They were straightforward with the plan - clear and precise, ensuring that I was well informed of the process and outcome. The execution was meticulous and exceeded my expectations. Moreover, the cleanliness post-service was remarkable, leaving no trace of debris or disruption.

They were on time and was the epitome of friendly and cheerful—felt like I had friends over for a garden party!

Overall, their service was excellent at every stage. The inquiry, consultation, customer support, day-of service, follow-up, and payment process were all seamless.

I had peace of mind and very happy with Vista. I highly recommend them to those in need of reliable and thorough tree management service.

I can’t say enough positive comment about James and Vista Tree. We were “ghosted” by 2 other tree management companies last fall. James came by and provided separate quotes for two very large trees on our property, both of which were a challenge to severely prune. They were a hazard and had to be addressed. The quotes were delivered the next day after assessment. The team was here on two separate days (April 30 and May 7). They were efficient, professional and most importantly safe. Hollis, the arborist who climbed the trees was friendly and communicated everything he was doing to the trees as well as any changes he made once he was up in the tree. The other members of the crew (Syd and Pete, I can’t remember the others) were professional and friendly. They cleaned everything up and were open to any suggestions we had regarding disposal of the wood. I would highly recommend this company. We will be having them back again to do more work, in the fall.

Leaside neighbours take note!! Exceptional and professional service from start to finish. The team at Vista Tree Management responded to an urgent and critical situation. They were efficient, skilled and courteous. They handled the tree removal with precision and left our backyard immaculate. I highly recommend this team for your tree removal needs. They beat the competition by $1000+

James and his team did a great job pruning and trimming our old silver maple. James answered all my questions, provided expert advice and had his team do the work shortly after. The workers were professional, cleaned the space well, and were really efficient. Would definitely recommend Vista Tree management!

James was great! Very professional and you can definitely tell he knows what he’s talking about. They provided a quote in a timely manner booked us in for the tree pruning within a few days afterwards. The job was done quickly, professionally and the crew was friendly and polite. They cleaned up everything once the work was completed. Highly recommend!

Safe, fast, personable team - did a great job with tree trimming and removal! Note: the removal of a tree was not on the original scope and they still made it happen!
By the end of the day, I wouldn’t have even known they were there.

Very Happy with the professional advice and service we received from Vista which was promptly done. The follow-up to ensure we were happy with the work was appreciated.

Highly recommend! Michal came by first to take a look at things and provide the estimate. He’s obviously passionate about what he does and I learned a ton about my tree that I had no idea about! He gave me the confidence I needed to schedule the work. James and the “J-Crew” arrived on the scheduled day and were super friendly. The team did an amazing job with trimming my large overgrown maple and a fantastic cleanup job. My yard looked better than before they arrived. Will definitely have them back for future maintenance! Thanks Vista!

Great service from a great crew of people! The team was amazing from consulting on best ways to tackle the project, safely removing the trees and making sure the job was done to satisfaction. Would highly recommend and definitely use them again.

These guys are incredibly professional and by far the best arborist that have visited our home. And we've had many!

What impressed me the most was throughout their only concern was safety for my family and our property. With that and that only in mind they made all the cuts and changes that were required. When they left, I felt the most relief I felt about the trees in our backyard in a long time.

Truly appreciate your hard work and will highly recommend you in the future!

After doing a fair bit of research into Toronto-based arborists, we decided to go with Vista, and are very happy we did! From my first meeting with Mike when he came to give us a free quote, I was impressed with his knowledge and professionalism. Mike and his crew were punctual on the day they came to prune the deadwood from our very large Red Oak tree, answered my questions, and worked for 7 hours straight to get the job done. We were impressed from beginning to end, and wouldn’t hesitate to hire them again!

These guys are the best! Very professional, easy to work with and very nice people.
James was amazing in communication and and arranging everything. He is a wonderful person and professional. I had 4 different companies for the quotes and Vista Tree were the best by every criteria I had in mind. After the work was done they cleaned the whole territory even the mess that was here before them. I would definitely recommend them and will call them again when I need any tree work done. Thanks!
