Trước khi làm bác có đào lên xem có mấy con không? Chứ cái page đó nó nói ít quá th́ không cần:
Scout a lawn in late summer by digging several sections of sod 1 foot square and 2 to 4 inches deep. If they are present and feeding, you'll see them in soil. Follow these treatment guidelines based on the number of pests present:
0-5: No need to treat.
6-9: No need to treat a healthy lawn –unless animals are digging to feed on them. In a large yard, you may want to treat highly visible, used areas, but not treat the "back 40" section. A stressed, less healthy lawn will likely require treatment.
10 or more: This many will likely create visible damage to a lawn. Plan to treat.
