Worker safety
Re-entry interval (REI)
3 days (for sod farms)
Timing & weather
- Apply during late afternoon or early evening hours and after an irrigation.
- Irrigate lightly after application (not more than 1/2 inch).
- For best results apply the material in the early morning or late afternoon when the ants are most active.
- Applications made under prolonged hot and dry conditions may be ineffective due to the location of the ants deep within the nest.
- Treat early or late in the day, as wasps are generally less active during these times.
