Stronghold Spot On solution for dogs and cats helps to stop fleas and helps to prevent heartworm. Helping to kill fleas, lice, worms and mites with just one application per month.

Stronghold spot on should be administered at the back of the animals neck and in direct contact with the skin. Not only will the solution kill the fleas and mites on the skin and ears but the liquid is absorbed in to the body through the skin in to the blood stream where it then begins to work on parasites within the gut.

Stronghold works on the following:

  • Biting Lice
  • Sarcoptic Mange
  • Ear Mites
  • Heartworm

Absolutely Brilliant! First time I've tried Stronghold and isn't the last: I'm here ordering some more. I have 3 cats of my own and a few visiting cats so you can imagine what the infestation was like! It was driving my up the wall! Well I combed my cats after 24 hours and was finding dead fleas already and I'm still finding them 3 wks on. The treatment just keeps on working. And it didnt spread on the fur like the other brands do, it was obsorbed straight into the skin. Would strongly recommend Stronghold.
