• DECTOMAX Pour-On is highly effective against cattle grubs. However, proper timing of treatment is important. For most effective results, cattle should be treated as soon as possible after the end of the heel fly (warble) season. Destruction of Hypoderma larvae (cattle grubs) when these grubs are in vital areas may cause undesirable host-parasite reactions, including the possibility of fatalities. Killing H. lineatum when it is in the tissue surrounding the gullet may cause bloat. Killing H. bovis when it is in the vertebral canal may cause staggering or paralysis. These reactions are not specific to treatment with DECTOMAX Pour-On, but can occur with any successful treatment for grubs. Cattle should be treated either before or after the migratory phase of grub development. Consult your veterinarian concerning the proper time for treatment. Cattle treated with DECTOMAX Pour-On after the end of heel fly season may be retreated during the winter for internal parasites, mange mites, or biting and sucking lice without danger of grub-related reactions. A planned parasite-control program is recommended.
