| What is
IPM?
Integrated Pest
Management is a process consisting of the balanced use
of cultural, biological, and chemical procedures that
are environmentally compatible, economically feasible,
and socially acceptable to reduce pest populations to
tolerable levels.
Integrated means
many strategies are used together to avoid or solve a
pest problem. For example, strategies would involve
understanding of pest life styles, knowing how to make
structures unattractive to pest, and knowledge of which
pesticides are least toxic to non-pest animals and
humans. In addition, understanding the tolerance level
of the individual property owner is important in knowing
how aggressive pest treatment must be.
Pests are unwanted
organisms that are a nuisance to humans or domestic
animals, and/ore can cause injury to humans, animals,
plants, structures, or possessions.
Management is the
process of making decisions in a systematic way to keep
pests form reaching intolerable levels. Small
populations of pests can often be tolerated and total
eradication is often not necessary.
Why is IPM better than
traditional pest "extermination"?
Older methods of
"extermination" used increasingly powerful and
poisonous chemicals to eradicate pests, and resulted in
environmental damage, and creation of chemically
resistant pests. Many of us are familiar with DDT and
damage to bird populations, and of resistance of the
cotton boll weevil to pesticides.
IPM is much gentler to
the environment, and control methods are more narrowly
targeted to specific pests. Instead of artificial
pesticides, many of the currently used chemicals are
based on extracts from plants and are harmless to people
and animals. Some depend on insect hormones, or
interrupt insect life cycles. Because insects are built
very differently from plants, humans, and pets, these
more natural chemicals are gentle to these other
organisms. This results in less use of pesticides, less
potential danger to humans, pets, and plants, and less
development of resistance to pesticides so that low
doses remain effective.
However, Integrated Pest
Management requires a more active role on the part of
the home owner and a partnership relationship with us
for maximum control.
IPM Steps
IPM is a process that involves
four major steps:
- Prevention -
consider the life style of the pest, and use.
Example: it is a good idea
to keep wood away from a structure, making for a
sort of desert that can be daunting for termites to
cross. Keep mulch away from foundations and keep all
plant life from touching the structure.
- Monitoring -
check for signs of the pest and for maintenance of
barriers to infestation. Example: our termite
monitoring involves monthly checking for signs of
live termites in the wood used in the monitor
stations.
- Assessment -
establish a standard for when action must be taken
to regain control. Example: if more than five
termites are seen in a monitoring station, that
triggers action. One or two termites are not always
a trigger for action because there are not
sufficient numbers to carry bait back to the nest.
It is often advantageous to wait for the termite
colony to show real interest in the monitoring wood
before switching them to poison bait. This
assessment is based on knowledge of how termites
act.
- Action (control
measures) - act when pests have exceeded the
threshold amount. Example: once termites have
signaled their nest to feed on wood in a monitor
location, shown by many termites in a monitoring
station, switch to bait in that station. The
termites will eat the bait and bring it back to the
nest, which will cause their nest mates and their
egg-laying queen to die.
The examples are about termites,
but we use the same steps for all pests. We are happy to
describe our process if you are interested. We will work
together to determine a tolerance level you are
comfortable with (sometimes zero) and we will help you
achieve that level. Once an immediate problem is
handled, we seek to work with you to prevent future
problems.
