After a fast trip to the vet for advice and supplies, we washed the maggots off with cold water, and treated her with injectible ivermectin, long-acting penicillin, and something for pain. We sprayed the area with scarlet (wound) spray and covered it with an old T-shirt. We sprayed the rest of her with fly spray and kept her inside.
The shearer arrived the next day and we sheared her in a standing position. We then washed and patted dry the affected area, applied more scarlet spray and gave her another injection for pain. We covered her hindquarters with a clean T-shirt to keep the area as clean and dry as possible. She was feeling a little better by now, and starting to eat again. Her milk supply had decreased, however, and we were supplementing her lamb.
We washed and treated her twice a day for the first few days, and continued the pain treatment for the first three days. By the third day Wendy was feeling even better and eating more aggressively.
On the fourth day, at the suggestion of Dr. Tim Slemp, we started applying honey to the damaged area. The honey was much less painful on her raw skin than the scarlet spray had been, and her recovery seemed to really speed up from this point on.
A few days later, new pink skin is emerging.
Treatment of the affected area with raw honey promoted rapid healing.
Six weeks after treatment began, Wendy is almost completely healed.
A few days later, Wendy’s milk was coming back and her lamb began to nurse again, and a couple of days later we were able to stop the bottle feeding altogether.
We continued the washing and other treatments for two weeks. Four weeks after the treatments began, there was soft fleece coming in all over her back and hindquarters.
I would use a large syringe and fill it with betadine and warm water, and squirt it up in there to flush out any more of the little buggers that may have been missed. If you have diatomaceous earth, powder his rump area with it and around his glands- even if the flies lay more eggs, it should dry the eggs up and prevent another hatch. There are fly repellant ointments, but I would be hesitant to use them because he may lick it off- you would have to check the ingredients thoroughly. MaggieJ uses catnip as a fly repellant, so if you have any, get some leaves and roll them in your hands to crush them, and then rub the leaves on his nether regions. It may help and it can't hurt.
I would hang some sticky traps near his cage too.
Good luck! Let us know how he does.
“In scientific trials we've demonstrated that lice were eradicated from sheep dipped in diluted tea tree oil, using concentrations of between one and two per cent.
“Our sheep trials confirmed our work in the laboratory, which suggested that a one per cent tea tree oil formulation could kill both lice and their eggs.”
Tea tree oil also killed blowfly maggots and eggs and prevented flies laying new eggs on treated wool for up to six weeks.
The antiseptic effects and wound-healing properties of tea tree oil may also help flystrike resolution.
