preen in backyard mulch

Asked March 23, 2019, 9:48 AM EDT

Getting estimates for spring mulching. One landscaper uses preen in the mulch. This may be very helpful as I spend a lot of time pulling weeds out of my mulch through the season. But, is the use of preen safe for dogs and backyard birds, squirrels, and other wildlife, including earth worms?

You will have to read the label for more information, the type of weeds controlled and the plants that they can be used around, and any environmental hazards.
You can also contact the National Pesticide Information Center for toxicity information regarding pets, wildlife, etc. Please let them know the active ingredient on the label of the product you are using.
