Rick from Merritt Island writes,

How often should I use Bifren XTS for chinch bugs in my St. Augustine lawn?


You can use Bifen XTS every two weeks as needed to treat for chinch bugs. The Bifen XTS product label also recommends: To maximize efficacy against sub-surface pests, apply Bifen XTS with a nonionic surfactant in enough water to ensure the spray penetrates to soil-thatch matrix. Water treated areas with 0.25 to 0.5 inches of water immediately following application, taking special care to prevent run-off or puddling.
