  • You may like to change your flea collar depending on the instruction indicated in the box. This differs for every style and brand. However, many common and famous brands usually last for around 6 months.
  • Decontaminating your flea collar several days before using it is a nice idea to give it a chance to liberate itself from any overwhelming odor. After several days, you will find it more bearable to use.
  • You must suit it properly but see to it that it is not too tight. Remember that it is necessary to fit the collar just right on your pet in a way that he cannot get access to chew or bite it. Fit it loose enough to prevent your pet from choking.
