Curative insecticides for white grubs and bluegrass billbug are mutually exclusive.

• A. True
• B. Sometimes
• C. False
• D. Not sure

Answer: (C)

Curative control targets pests that are already feeding in the turf, and the key is what a product is labeled to treat. White grubs and bluegrass billbugs can sometimes be affected by the same insecticide, because both larvae feed on roots and some products have broad enough activity to kill both. So you’re not restricted to a separate, exclusive product for each pest—the existence of label claims for both means a single curative option can sometimes handle both issues. Always check the product label to confirm which pests it is approved to control and at what timing, but the idea that you must use entirely different products for grubs versus billbugs isn’t true.
