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?
