We sometimes take it for granted that everyone understands
what Integrated Pest Management means. It is one of the cornerstones of our
tree, plant and lawn health care programs. But, since many of our clients have
questions about the practice, let me give you a little more information.
Decades ago, when synthetic pesticides were developed, they
were used liberally. And they were effective at killing pests – but they killed
many beneficial insects as well. This means that the natural balance in the
area where they were used was severely disrupted. The whole food chain was
interrupted, and often the birds disappeared along with the bugs.
The concept of Integrated Pest Management (IPM) arose from a
desire to work within the natural order. So, rather than saying "We’re just
going to eliminate all aphids", we ask the question, “Are these aphids being
controlled by their natural predators, like lady bugs and praying mantises?” Or “Are there certain plants that need to be
protected, because they are particularly vulnerable to aphids?” If the aphids
are growing out of harmony with their natural predators – perhaps on an
especially alluring rosebush -- we step in with a very targeted treatment to
manage their population, either by killing the adults, or more likely,
preventing the larvae from emerging. So rather than indiscriminately spraying
insecticide all around a garden, we will apply horticultural oil (to prevent the
emergence of larvae) to the aphid-loving rosebush.
Integrated Pest Management isn’t always organic – but increasingly,
we find that natural or bio-rational products are best for these narrow-focused
targets. And we’re always exploring
organic options wherever possible.
So how do we know what to use and when? One of the
fundamentals of Integrated Pest Management is inspection. Our technicians go out and inspect our clients’
properties several times a year, and then use products that specifically respond
to any observed insect or fungal threats.

And managing insects through applications is just one tool
for keeping plantings healthy and beautiful. We can also limit the spread of
insects or diseases through selective pruning of infested branches as well as by
improving the overall health of plants (and their resistance to pests) by
improving the soil.
