Most yard grass and week killers contain toxic chemicals that can be harmful to pets that walk through the lawn or garden after application. There are ways to kill grass and weeds without the chance of harming pets.


Vinegar makes a safe, effective weed and grass killer. Pour white vinegar into a spray bottle and apply it directly to the weeds or grass. It may take repeated applications to thoroughly kill them. Lemon juice can be combined with the vinegar for a stronger solution.

Corn Gluten Meal

Corn gluten meal, found in the natural foods section of many supermarkets, is a preemergence herbicide that works by stopping the growth of germinating weeds or grass. Pour corn gluten meal directly onto the bare ground and water it. Corn gluten meal works on germinating seeds only, rather than established weeds.

Soil Solarization

Soil solarisation safely and organically kills unwanted plants and, as an added benefit, rids soil of other garden pests, such as nematodes and fungi. Cover weedy soil with clear, plastic tarps during a hot period of the year. Leave the tarps undisturbed for at least four to six weeks. The soil underneath heats up, killing unwanted grass and weeds. In cooler weather, leave the tarps on the soil for up to eight weeks.
