Protect Your Trees from Harmful Insects and Common Tree Diseases

Arizona’s hot, dry climate can be tough on trees—and unfortunately, it also attracts a variety of pests and pathogens. At Techer’s Tree Service, we help homeowners and property managers identify, treat, and prevent tree diseases and pest infestations before they lead to serious damage or removal.

What’s Going on Beneath the Bark? The Value of Tree Health Checks

Tree health monitoring is essential to maintaining a safe, attractive, and valuable landscape. When issues go unnoticed, trees can develop structural weaknesses that lead to falling limbs or even full collapse, posing serious safety risks and potential liability. In many cases, untreated problems can progress to the point where removal is the only option. Pests and diseases may also spread to nearby vegetation, causing broader damage across your property. Beyond safety, unhealthy trees can diminish curb appeal and lower property value. That’s why Techer’s Tree Service takes a holistic approach—evaluating everything from canopy to root collar to catch problems early and keep your trees thriving.

Common Tree Pests and Diseases: What Every Property Owner Should Know

Some of the most common issues we see in the Phoenix area include:

  • Sooty mold and scale insects on citrus trees
  • Borers in palo verde and mesquite trees
  • Fungal infections like root rot or leaf spot
  • Aphids, whiteflies, and spider mites causing leaf distortion or discoloration
  • Powdery mildew, especially during humid monsoon seasons

Early detection is key. Signs like wilting, leaf drop, bark cracks, or insect activity near the trunk can indicate a more serious issue.

What to Expect from Our Disease & Pest Services

We begin with a thorough inspection and a species-specific diagnosis to identify the underlying issue affecting your tree. Based on our findings, we may recommend treatments such as insecticidal or fungicidal applications, pruning of infected limbs to prevent further spread, soil enhancements to boost tree immunity, or targeted injections for more serious infestations or diseases. Throughout the process, we implement integrated pest management (IPM) strategies that prioritize both effectiveness and environmental responsibility. Our goal is to restore tree health while minimizing impact, and we follow up with ongoing monitoring to ensure lasting results.
