Dear John,
I agree with every point that you are making regarding integrated pest
management and not indiscriminately using general pesticides, but I have
heard quite the opposite about spiders.  I have been told that they are
the most sensitive creatures to pesticides and will be killed first.  I
have also heard that they are "canary in the coal mine" indicators and
that if you have no spiders you probably have some residual pesticides in
the environment.  Am I misinformed?
Sincerely,
