James from Grosse Ile, Mi writes

If using Bifen IT for armyworms in my lawn, when should a do a follow up application?

When I initially applied, I had moths, worms and pupa present. Based on the life cycle of the army worms, how long would you recommend waiting before a follow up treatment to address the pupa which would not have been affected by the product?


For Armyworm control, Bifen IT is applied at 1 fl oz per gallon of water per 1,000 sq ft with repeat applications done every 30 days. Please view our Armyworm Treatment Guide for more information.
