What Are Secondary Invaders?

Resources: Tree Problems

Asian Long-Horned Beetle A Common Secondary Invader
Asian Long-Horned Beetle A Common Secondary Invader

Many insects and diseases rarely infest healthy trees; instead they are typically secondary invaders. Secondary invaders are pests that only infect trees after they are in a weakened state. This weakened state can be created by what are called stressors. Stressors are environmental or human inflicted situations that increase the tree’s susceptibility to attack; similar to how our immune system lowers when we don’t get much sleep, thus we end up catching a cold. For trees, stressors typically include drought, soil compaction, sun scald, or injuries. When a tree is exposed to stressors they become an easy target for insects and diseases.

Many theories have been proposed for why this phenomenon occurs. The two biggest being, the idea of insects and diseases responding to tree stress pheromones and the idea of insects and diseases responding to trees running a fever when stressed. At the end of the day researchers are not positive how insects and diseases spot weakened trees but they are positive it happens and that it’s imperative to protect our trees from becoming easy targets.

Think you have a secondary invader problem? With our Canopy Protection Program our Arborists will be able to identify your secondary invader and not only treat it but treat the underlying stressor to combat future infections and infestations.

We have been using RTEC for years and were very pleased with the recent tree maintenance work they did for us. As always, we got good advice from their arborist Ben,. The crew that did the work is highly skilled, and they did a great job trimming our trees. They worked safely and efficiently, in addition to leaving the yard clean after they finished the work.

RTEC was at my house today to removed a large Magnolia that was badly damaged by the recent snow. They did a fantastic job at a very reasonable price. They arrived right on time, worked efficiently and quickly and cleaned up so well it was hard to tell anything have been disturbed. Over the past several years, I have used RTEC for all the services I checked above, and have always been very pleased with their service and professionalism. I also appreciate that they are not eager to take down trees that don't need to come down. In this case, the damage was too extensive for the tree to recover.

Once again, RTEC has done a great job. The team showed up right on time and performed all the work that we agreed to. They kept us informed as to progress, coordinated with us concerning our maple, and made recommendations concerning ongoing support for our trees. At the end of the day, they thoroughly cleaned up the debris and left our yard in pristine condition. WELL DONE.

Not our first time but this time was tricky removal of a large dead tree leaning on a healthy tree. Quick response for estimate, good timing to removal, all clear and healthy tree still fine.

We’ve used RTEC for many years for tree maintenance and can’t say enough good things about their service. We use them for tree trimming and for regular treatments to maintain our trees’ health and deal with pests and prevent disease. Their arborist Ben has been especially helpful with advice. RTEC also been especially helpful in emergency situations, once coming to cable a massive, heritage oak in our yard right before a hurricane was about to hit. Highly recommend.

RTEC did an excellent job onsite of removing dead branches from our 80+ year old trees, and trimming other growth too close to our home.
