Nutrients obtained during this stage in the life cycle are essential for the larva’s significant growth. Cattle grub larvae are true maggots, with retractable heads and no sclerotization or legs.

In the early s this antiparasitic compound was established as one of the most effective materials ever developed for systemic use against cattle grubs.
