DDVP is an organophosphate insecticide. Organophosphates are a class
of insecticides that affect the nervous system of the target pest.
Overexposure in humans can result in neurotoxic symptoms.
This is what is left on your plants when you use these strips. I do not argue about their effectiveness, i am only trying to advise people what they are really ingesting. Organophosphates short circuit the synapse in brain cells. Just because you can't see anything on the plant doesn't mean the vapors are not on the plant parts. If this is what you choose to use for pest control instead of organic products like the Neem applications you certainly have the right to use it. I am only trying to point out the dangers of this product, especially when you are burning it and putting it into your lungs. If you think your flowers are not covered with this chemical from vapor applications you are in denial. Califormia is in the process of restricting use of this in their state because of health concerns.
