Ticks can attach to your pets any time the temperature exceeds 4°C, but activity will increase above 7°C, so look for greater tick attachment when walking through grass and shrubs/bush. Many people find the oral pill Bravecto, given with a meal, to be a convenient treatment administered every three months for dogs. For cats, there is Bravecto topical therapy every three months. Both products kill fleas also. If you are travelling with your pet east of the Rockies or into the southern US, you should consider using Revolution or Advantage Multi as your flea and tick control, with heartworm protection.
