Is it safe for pets to be on the lawn after applying pre-emergent herbicides? Generally, it’s safe for pets to return to the lawn once the pre-emergent herbicide has dried completely. This usually takes a few hours, but it’s important to follow the specific instructions on the product label for the best guidance.
What Are Pre-emergent Herbicides?
Pre-emergent herbicides are a type of chemical used to prevent the growth of weeds before they emerge from the soil. These herbicides are typically applied to lawns and gardens to control annual grasses and broadleaf weeds. The active ingredients form a barrier on the soil surface, stopping weed seeds from germinating.
How Do Pre-emergent Herbicides Work?
- Application Timing: They are applied before weed seeds germinate, typically in early spring or fall.
- Barrier Formation: The chemicals create a barrier that inhibits cell division in young seedlings.
- Effectiveness: They are effective only on seeds, not on existing weeds.
