Maggots on sheep

Neighbour not well. Asked me to check sheep yesterday. About 1000 head.

Took 10 mins to catch this one, ewe lamb shorn 3 weeks ago and a dose of ectofly a week after.

The white flecks are fly eggs , I’ve never seen so many eggs in one lamb.

Had to do all remaining lambs again other day, Clikzin. Crutched the wet-dirty ones, and found half dozen struck. Click was applied 25/04.
I believe Crovect and similar to be pretty much a waste of money for protection, doesn't hardly do 3 weeks this weather.

I Dysected all the long-term keep ewes and lambs and Crovected the short-term keep lambs over the weekend, based on their respective meat withdrawal periods.

I last applied Dysect on all the ewes/lambs the following day after shearing which was nearly 13 weeks ago. Dysect is claimed to be effective for 10 weeks for flystrike. Had one ewe lightly struck in the wool last week but didn't get to the skin. Thought I'd pushed my luck far enough, especially since the last pour on didn't have much wool to soak into and would usually wait for 3-4 weeks worth of wool regrowth.

Hoping the Crovect will do its thing. Dysect could be used in chemical warfare with how harsh it is, but it bloody works a treat.

We went all out on alternative measures this season, red top fly traps and garlic feed blocks, tempting fate but does seem to have made a difference.

Everything here was done with Clik Extra in late May or early June, which seems to have stopped blowfly ok (everything pretty clean too, which helps).
However, I’ve done my yearling rams, shorn ewes and pedigree lambs with Ectofly too this last week. They are all being eaten alive by biting flies, not just on their heads but bits on their sides too.

Ideal fly weather I suppose, but never seen anything like this. Poor beggars. :(

Do you use Dysect at all Neil?

Assuming meat withdrawn lengths are not an issue, when does it become worthwhile to get a mobile dripper in to control maggots?

I use Dysect twice a year. Don't get maggots. Costs about 80p a ewe or 40p a lamb. So if dipping is cheaper than that for fly control go for it

I expect it will depend on your labour costs and if you trust the person using Dysect to correctly cover all sheep.

It takes me two half days to do 250 sheep, that includes setting up pen and race. Run the sheep from one field into their next grazing field via the race so gathering is easy. Ewes one day, lambs and rams on another.
Spray down back and around tail head. Cost about 50p in labour/ sheep.
 
We click our lambs at their 1st vaccination, they are cheaper to do at that stage, also any later and the withdrawal tends to mean holding back the first lambs that are ready for market.
The lambs that are left after the Click cover period are covered with Crovect.

This year is the first time that we haven't had full coverage from click, lambs started to get struck 2 weeks inside the protection window, it's also the first time I've ever let someone else apply the click, so I can't say which is to blame.

5 lambs were struck out of around 100 that are left on the farm, all bar one were spotlessly clean as well.
