As title really, I am wondering if there are any effective alternatives to Crovect/Dysect etc? Unfortunately I have been ill with allergies, including anaphylaxis and have been advised against using these, even with protection, as well as staying away from treated animals as I seem to react adversly to the chemicals in them, just wondering if anyone has come accross any suitable longlasting and safer alternatives - we try and get our ewes and rams shorn early and haven't treated them at all for the last 2 years and haven't seen any strike on them, however the lambs need treating as they can get blowfly problems. Thinking aloud we could consider shearing the lambs although I feel that could affect the saleabilty of those going as breeding stock.
thanks for any advice
