A bit of a follow on post from my earlier post about feather mites. Sorry i am bombarding H&H this morning. yesterday i applied some Net Ex feather mite powder, this morning i went and applied front line spot on to his skin under his feathers thinking there is no way that Powder can work at £5.00when i went to see him this morning he wasnt itching and ive just gone over and again he isnt itching. I presume the front line would take a bit longer than 4 hours to work so im now wondering if the Powder is actually doing something. I have just seen the key ingredient is DIATOMACEOUS EARTH. I have found a page on ebay that is much cheaper than buying Net ex powder. https://www.ebay.co.uk/itm/10KG-DIAT...%3D&rmvSB=true Has anyone else used this with success?
