How toxic is Demon WP to fish and dogs?

I have a pond with catfish approx. 50 yards from my house and during hard rains water runs off form the house area into the pond. I'm having a big problem with scorpions.


Demon WP is not a problem to use around pets as long as you apply it according to the product label. Once Demon WP is mixed with water, it is only strong enough to kill small insects. You would not want to leave the jar of Demon WP open where dogs could get into a large quantity of it. It is always a good idea to keep pets and children out of the area while you are treating. Once the product dries, usually after 30 minutes, it is perfectly fine to allow pets and children back in the area. However, all pesticides are very dangerous to fish and aquatic life. You would not want to use Demon WP or any other pesticide near a body of water. 50 yards away is a good distance, but if the land sloped down towards the pond, then there may be a concern. If it does not, it should not be a problem to treat around your home that is 50 yards away from the pond.
