Pet Safety

As with all pesticides, keep pets inside when applying.  After application water the Doucide at least once, if not twice. (first watering will cause granulars to react second will lock them into the ground) Allow this to settle for a few hours and then pets can return to area.  We apply in the morning using the dew to help with particle activation. Then water in right away. Allow the sun to dry for a few hours and the pets can return.

Spreader Settings

It’s impossible to list ALL the spreaders on the market, so keep this in mind.

1- The product has a VERY small particle size, so start of with the opening just over 1/8″.

2- Measure your yard areas and make sure you are applying the right poundage. Use the online calc to measure.

3- It’s better to start off light and go back with second pass in a zig zag.
