Staykil is for any home that has been infested with fleas. 95% of fleas actually live in your home and so only a small proportion are on your pet. It is extremely important to treat your home alongside you pet.

Why Staykil?

  • Treat your pet regularly with a flea treatment to prevent re-infestation.
  • Insecticides do not kill pupae and adult fleas may be seen emerging for several weeks after treatment. Continue to vacuum your home until they are gone.

Why am I still seeing fleas after I have applied Staykil?

Due to the complicated flea life cycle, the time it can take to fully eradicate the burden is dependent on the severity of the infestation. Staykil is an insecticidal product. It contains two actives ingredients: permethrin, an adulticide which kills adult fleas and S-methoprene, an insect growth regulator which controls eggs and larvae for a full 12 months.

Insecticides do not kill pupae and adult fleas may be seen emerging for several weeks after treatment. All emerging fleas will be killed by permethrin within 24 hours in the first few weeks after treatment but may still be seen by owners. These newly emerged fleas can be recognised because they appear smaller than those typically seen on the animal. Vibration stimulates hatching and regular vacuuming encourages these small adults to hatch from their pupae and come in contact with the adulticide. Pets treated with a topical treatment which includes an adulticide can be allowed to return to the home as they will also encourage pupal hatching and will attract and kill the emerging adults when they jump on to them.on. If treatment has been made correctly, the fleas seen one day are all dead the next day. However, pupal hatch may continue for some time. We do also recommend to use a spot on treatment prescribed by your vet alongside protecting the environment.

In addition to this once the product has been applied to all area’s, there is no need to respray the areas and the active ingredients will last for 12 months.

If you are ever worried about your pet please go to your vet for further advice.
