First strike of the year, but caught very early so little harm done to the ewe. We had decided to spray them with Crovect today and were doing the routine feet and other checks when we found the little buggers, just about an inch square. I think we got there just in time.
Crovect is wonderful to have in your hand if you do have a strike.
-
We had one struck today as well. She was being bothered by flies so I brought her in. Not bad but so early. She only lambed about 2 weeks ago!! Now shearing all the sheep & not sure my last ewe has lambed!
-
We dagged and Crovected ours on Friday. Fly strike gives me the willies - we had one last year but maggots in the wool only. Mind you, I do like spraying them with Crovect and watching them die ;D
-
we use crovect a couple of weeks after after shearing and keep them at bay until shearing using a product such as Blowfly Repel or Flystrike Plus (depends which one we have most stock of at the time)
:bunny:

COUPLE of points about crovect it only lasts 6-8wks and only protects the areas it touches. Vetrazin 10 wks CLIK 16 wks both whole body coverage. It is a nerve toxin so when treating lambs for maggots only apply at the recomended rate or you can cause organ failure,ewes being bigger are more tolerant.

I've been mulling over this and have always used Crovect in the past. However, wondering about changing to one of the others. Is it OK to use them on the ewes even though they have lambs in them? I'm always a bit worried about it running down onto the udder etc ::).

WHAT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!:o :o I thought it was only for 6-8 weeks but made sure the whole beast was safe. Surely it cannot just be where the spray lands, or why else would they say it covers the beast and why else do people buy it? Urgent guidance please :'( :'( :'( :'(
-
we found two today, got well caught out, horrable, one ewe had gone and tucked herself in the wooded area, couldnt save her :( but the other one was just a small patch, tomorrow evening we will treat them all with crovect !!! blighters so early this year with this early hot weather !!!
-
Our Southdowns suffer with fly strike, Crovect is great but this year we are shearing early, tomorrow in fact. I'm determined to outwit the little blighters. One ewe is still pregnant so I hope the shearer is gentle.

shep would seem to be right - see

For ticks & lice Crovect is applied in a thin line and clearly protects the whole animal, but for blowfly the T-bar is used to give maximum spread and the data sheet very clearly states "THE PRODUCT WILL PREVENT BLOWFLY STRIKE ONLY ON AREAS COVERED BY SPRAY."
Having said which, so long as you can get yourself the required distance from the sheep, you can get a pretty good coverage using the T-bar : you can see where it's landed by the dye.

battles oil is excellent for strike and not that expensive, wear good gloves and rub it in, but clip affected area away first. dont get it on your skin
-
GARDEN COTTAGE i agree and use maggot oil to treat the odd young lamb with stike as its safer and helps healing. SHEARLING crovect is an excellent p roduct and the back of the pack clearly states all the facts, you cover the main areas of stike eg back and bum , but you can get it on the stomach area. BLINKERS bit confused do you mean lambs in them ie pregnant or on them ie suckling , wooly or clipped. VETRAZIN AND CLIK both have something called fleece bind which makes them stick so actually less runny than crovect. NONE of these products are recomended for sheep before shearing ,once clipped you have to re do ,plus not good for the shearer to come into contact.

Ooops.... yes, meant 'on them' rather than 'in them' ;D
Crovect is pretty wicked stuff and rots metal stuff - hence the gun being plastic :o
-
Did not have my specs on and left the Crovect to the OH! Stupid I know :dunce: So we did the T stripe down the back and over the bum. But what should we do about the other bits of their bums/parts? We have dagged them first, due to get their hair cuts end of May we used VETRAZIN last year. Prehaps should have stuck with it.
-
I thought Vetrazin had been phased out. We use a garden hand sprayer to apply Crovect to our little sheep - the Tbar thingy just wasted nearly everything and it's too expensive to pour on the grass. We carefully measured how many mls to spray on or rather how many squirts equals the recommended dose, so not overdosing, but much easier to reach all parts, including the vital perineal area where maggots can hide.
We have just heard a story of someone who a few years ago sheared his sheep early because of hot weather, only for it to turn very wet and cold - he lost a couple of ewes overnight to pneumonia. It is worth crutching/dagging your sheep a few weeks prior to shearing - keeps the bums clean against flystrike but also helps at shearing as no dags in fleece roll.
Please remember that agents such as Crovect should not be used on fleece closer than 3 months before shearing for the sake of the BWMB sorters, to avoid pollution of scouring water, or for the health of handspinners and felters if you are selling to the craft market.

Fleecewife can you explain how that works. If the product is only effective for 6 weeks how come it's dangerous for 3 months? I hadn't thought of that so it looks like i will have to throw all my fleece away. Just the 2 sheep mind you as my wilts have no usable fleece.

I expect it's a blanket quote to cover all products including clik, and to make sure that all the stuff has gone from the fleece. Now you've got me wondering whether if you were to leave the fleece lying out in the rain for 3 months after shearing it would then be ok to use, as opposed to one left rolled in a bag. I don't know the chemistry of the anti-fly-strike agents or just how they break down - does anyone else have this info?
-
I spilt some crovect on my hands the other day and all my fingers went numb!! No nice. The product loses its efficacy after 6 -8 weeks, but still is toxic residue.
-
Ah, Crovect is evil stuff. Having had some splash on my jeans and my legs ached and were red for hours I now wear waterproofs when we're using it - and it rots the flexothane leggings. After working out what was making me wheezy and my eyes itch, I also now wear latex gloves, a hanky over my mouth and goggles when we're using it and wash my hands very thoroughly when we're done - and try not to rub my eyes for some hours after.
Small price to pay to stop the girls and babies getting strucken, but I do worry about the wider environmental impact.
I do wear protective clothing for Vetrazin too, but I do think it is less noxious to humans.
-
Clik interferes with the reproductive processes of the little blighters but has a 40 day meat withdrawal period and a prohibition on shearing for 3 months because of residues in the fleece. That's why it's effective for longer.
Novartis has launched Clikzin recently which has a 7 day meat withdraw but I've seen little else about it.
Yer pays yer money...

CLIKZIN is i believe to replace vetrazin, lasts i think 8 wks it is diluted clik designed to allow fattening lambs to be sold after only 7 days
