Did you know one of the main ingredients in tick repellent is garlic oil? This scent repels many other insects too (humans also!). To make your own all- natural tick spray add 4 cloves of crushed garlic to 1 tablespoon of mineral oil and let sit over night. In the morning remove the cloves and mix the garlic oil  with a quart of water and a squirt of dish liquid. Add this mixture to a spray bottle that attaches to your hose and water your lawn. The smell of garlic will dissipate in a few hours but the ticks will still smell it and keep away.
