Review: Excellent product. - I wont use anything else..really does work.
Review: What to do with a dog flea infestation .... - I have 3 cockapoos, no fleas in 10 years then an outbreak, after a few months of failures I found a process that worked for me and solved the problem: 1. Johnsons 4fleas tablets, taken with a ham slice or two after lunch. Kills the fleas and eggs after 6 hours (lasting 24 hours). 2. Boil washed all household bedding and dog blankets soon after. 3. I hot showered the doggies, I dont think it makes any significant difference what shampoo you use, flea related or not. I stuck with a tried and trusted normal shampoo which does not irritate them. Then gave them the dreaded hairdryer so I could manually check and comb out any fleas and eggs. 4. I was told by a vet that flea "treatment" i.e. pipettes they have every 4 weeks should be changed from time to time as fleas (90% are from the home) become immune, so I switched from FIPROtec to Advantage (both from desertcart) and applied the next day (within 24 hours of the Johnsons 4fleas tablets). Treatment was due in a weeks time anyway. Resolved the flea problem .... time will tell for how long.

## Questions & Answers

**Q: What are the expire dates for these tablets?**
A: we always have a packet in as our lab picks fleas up fairly regularly and have used 6-9 months apart.  hope that helps

**Q: how long does one tablet last**
A: I'm not really sure how long it last just that it act almost immediately! I noticed the fleas dropping off after half an hour!...but it does say you can dose again the next day so I suppose it depends on how bad the animal as fleas and if their in carpets or animal bedding where they can jump back on animals. Hope this helps Linda

**Q: What are the expire dates for these tablets?**
A: The box I bought a month ago has an expiry date END 03/2022.

**Q: Will these also kill lice?**
A: I don't think so. Lice is not from the same family as fleas and therefore has different biology. It would be written on its leaflet if it was able to kill lice.

### ⭐⭐⭐⭐ Great for killing fleas
*by L***W on 22 October 2024*

These are great for a flea problem and used with a regular spot on flea treatment and a decent household spray, I found spot on, by its self wasn’t enough to tackle my problem. How they work is they kill every single flea on your dog and start working in about 15mins but they only are effective for 24 hours, they are safe to use daily but I don’t use them that often but if you also put a spot on at the same time along as the spot on is due and if your vet has approved, it will help with any fleas that jump on after the tablets run out of effectiveness.
