Tips to know when trying to get rid of fleas on cats
- Please, note that your strategy to get rid of adult fleas is not limited to a one off treatment of your cat only. You also need to be aware of certain information and to implement other types of treatments, as explained here.
- Certain products listed above help to control the development of multiple stages of immature fleas in the immediate surrounding of your cat. In other words, they help to break the flea lifecycle.
- It is likely that treatment must be repeated at regular intervals as to control and prevent a new infestation with fleas. It is important to carefully read labels and follow instructions provided by the product manufacturer.
- Fleas can appear any time of the year. It does not mean that someone’ s house is particularly dirty, hence care should be taken as not to stigmatise people with a household falling victim of a flea infestation.
- It is also worth noting that moving in a new house can trigger a flea infestation, due to immature stages being activated by the presence of external stimulation (human activity, temperature).
