yes you take a chance putting the chemicals on...unfortunately the natural remedies dont really work. i use revolution also which is great for the fleas but not the ticks and keylo is getting them not lola or cedric. so i am going to spray the natural oils that repel ticks on her before we walk to see if that helps.
BLEND TO COMBAT TICKS
Check your home and pet for ticks - look in his bed, window coverings, walls, etc. Burn the ticks you find to prevent them from coming back. Prepare the following blend by pouring the essential oils into a 10-ml bottle and adding organic vegetable oil to fill.
· 10 drops Tea Tree
· 10 drops Lavender
Apply 1 drop of Lavender and 1 drop of Tea Tree undiluted essential oils before extracting ticks from your pet. This will disinfect the inflamed area. It may sting a little bit (as alcohol would) but it works great!
