Rupture of the larvae during extraction may lead to a localized inflammation and abscess formation. Insecticide treatment . The advent of systemic organophosphorous insecticides in the 1950 s gave cattle producers the first opportunity to control cattle grubs on a large scale at a reasonable cost. The use of systemic insecticides allows control of larvae while they are in the early stages of migration and before they reach the backs of the animals. The insecticides are used during the autumn and early winter with the aim of killing the younger larval stages.
Enough insecticide is absorbed through the skin to kill the larvae.
These compounds should be avoided in January and February since severe reactions may occur due to the death of larvae in the wall of the esophagus or spinal canal. Insect Management Guide for cattle grubs Drinking water treatments of insect growth regulators generally do not prevent cattle grub larvae from reaching backs of cattle, but may prevent adults from eclosing from pupae, thus preventing reproduction. Insecticide-impregnated plastic strips applied to legs of cattle during the heel fly season prevented the appearance of cattle grub larvae in backs of treated cattle. Perhaps the most promising control technology for use in suppression of Hypoderma spp. The first to be developed was Ivomec R .
