After you choose the right pesticide for your needs, you should make a plan for your work. First of all, you should detect the areas that are prone to become tick shelters, like wood and bushes. See where those areas meet your lawn and spray the solution onto the lawn and onto the margin of the area where ticks live. This is called perimeter spraying.
The best way to do it is to call a professional, but if you want to do it yourself, you should know the techniques. First, you should put the solution inside a garden sprayer and attach a hose, if you have one.
You should wear long trousers and a long-sleeved blouse. Make sure that the pesticide doesn’t touch your skin and be careful to follow all the instructions that the manufacturer gives on the label. This way you will lower the chance of having the toxic side effects of the product.
