Combining an IGR with a contact insecticide in flea management can lead to what outcome?

• A. Worse performance and more callbacks
• B. Greatly enhanced performance and reduced callbacks
• C. No change
• D. High toxicity to pets

Answer: (B)

Combining an Insect Growth Regulator with a contact insecticide in flea control addresses both the immediate population and the next generation. The contact insecticide wipes out adult fleas right away, while the IGR disrupts development, preventing eggs and larvae from maturing into new adults. This dual action speeds up population reduction and keeps reinfestations from taking hold, leading to greatly enhanced performance and fewer callbacks. It’s not just no change or worse performance, since you’re attacking both current adults and the life cycle. Safety is still important, but when used as directed, these products are designed to minimize risk to pets.
