Insect and Disease Control

We offer two approaches to insect and disease control:

1. Target sprays or treatments:
An issue with a certain tree or group of trees is identified (example: winter moth caterpillar on a maple). One or two target treatments are then prescribed to treat the issue, with recommendations on how to follow up in the future.

2. Arbor Care
Our complete, season long spray and fertilization program is custom tailored for an individual property, with the ultimate goal being to avoid issues before they arise.  (Learn more)

These guys are scientists, not just tree cutters. They are very professional. We will use them again and highly recommend them. They were polite, personable and just great guys. WE had a Japanese maple trimmed back as well as some yew bush fixing and fertilization. They did the job to perfection. They were in and out and cleaned up the mess and took everything with them.

Kaiser is great, they have been so helpful to us in bringing back to life many of our Japanese Maple trees. We have several rare specimens and they were infested with Winter Moth and then with Cottony Scale. Last year they sprayed for both and did a deep root fertilization to all of our trees and shrubs and everything looks amazing this year. We couldn't be happier with the service. They are all very professional and very approachable. I highly recommend them!
