Even “conventional” medical doctors are calling for avoidance of the use of pesticides. Even small amounts of these toxins can be very detrimental to children’s health. And don’t let the “small quantity” of active ingredient fool you–even the solvent carriers are toxic to humans in many cases. The same applies to herbicides. I have posted links to natural options. My favorite “herbicide” is what we affectionately call a “weed dragon”–a torch that burns the weeds. Pulling weeds is also an option. For pesticides–trying sticking with natural soaps, boric acid powder, boiling water, etc (depending on the critter you’re trying to eradicate). Keep in mind that many of these insects are actually helpful to keep around, though!
