Mikeyp as far as im concerned permethrin works a treat,one of my usual haunts is a tick heaven, i used to have to pick them off me as i got down to were i was going,since using permethrin, ive seen them get on me as i brush past some bracken,then watched as theyve just dropped straight off (though i do worry when applying the stuff ''am i breathing this in'' its a nuero toxin i think)
