Will Onslaught Fastcap kill box elder beetles? How frequently should it be applied? Will I have to reapply if it rains?
Answer:
Onslaught FastCap would do a great job with box elder bugs. There is no need to respray Onslaught FastCap Spider and Scorpion Insecticide after a rain as long as the treated area was dried before the rain. You will apply every 60-90 days outdoors.
