BC Crazy Posted February 22, 2012 Share Posted February 22, 2012 I changed to Advantix years ago for that very reason. Frontline just wasn't working anymore for us. Link to comment Share on other sites More sharing options...

oakway Posted February 22, 2012 Share Posted February 22, 2012 Oakway- It's good to hear that you have no resistance problems. :) But the occurrence of resistance is a problem, and one that modern drugs will still suffer from, unless used wisely. Unless a chemical has a 100% knockdown rate the survivors will breed and develop mechanisms to counteract the drugs. It's evolution. Products like Q Drench combine chemicals to ensure a 100% knockdown. You don't rotate your horse wormers? http://www.virbac.com.au/p-virbacaupuben/display.aspx?srv=p-virbacau&typ=pubā©=en&cmd=view&style=styles/page2.xsl&select=PAGE%5B@ID$eq$PAGE_182%5D&generic1=ARTICLE_961&affp=& Injectable Ivermectin knocks worms flat. :) Link to comment Share on other sites More sharing options...
