    Default Kill lawn bugs with your hose, is it legal?


    When I go to hardware stores, I see bug killers that work with garden hoses. Why are these legal?

    Cautions

    For outdoor use only. Harmful if swallowed. Causes moderate eye irritation. Avoid contact with eyes or clothing. Wash thoroughly with soap and water after handling.

    How to Use

    Connect: Shake well before using. Connect sprayer to hose. Turn on water. Spray:

    If they kill bugs, how safe are they for humans?
    Why are they for use with garden hoses that connect up to the public drinking supply?
    Why are stores selling them?
    Why are inspectors allowing their sale?
    Am I missing something here?

    I believe that in this application one of these would be required.

    In my state, pesticide regulations require an anti-syphon device for any hose that is used to mix or spray chemicals. The type of anti-syphon is not specified.

    I think that I need this to kill the bugs and the ant hill on my lawn.

    Those garden hose sprayers have been around ever since there have been garden hoses. What's the problem? I've been drinking out of hoses for almost
    sixty years, and I ain't dead yet!

    This is an interesting question because I think that legally the companies that make these things have no obligation to adhere to plumbing codes however all sillcocks now require a vacuum breaker at the very least to offer some degree of back flow prevention however, pesticide and irrigation systems require an actual back flow preventer. You can ask the same question of the hose attached fertilization products also like Miracle Grow.

    The assumption, faulty as it is, is that the hose valve will have the mandated anti-siphon device attached to it. But, since the device works with an "aspirator" the material is NOT entering the water flow unless it is an "active" flow creating a Bornelli Effect at the nozzle, EXACTLY like a "post mix" paint gun.
