Brilliant stuff
Instantly effective. A quick spray round a few days ago and all my 'little friends' - 'friends' I've had for years, simply disappeared....... EDIT: A few days later and a couple of lone 'raiders' have had the temerity to show themselves. But I'm on the job. Will I have to adjust my star rating? Only time will tell. Watch this space folks.

Say Goodbye to Silverfish: An effective spray solution.
I recently tried out the Silverfish Killer Spray 650ML from READY STEADY DEFEND, and I must say, it has been highly effective in dealing with silverfish. I've occasionally seen silverfish around the skirting boards in my cloakroom and kitchen, especially near the basin and sink. I had never tried a specialist cleaner before, but this spray has proven to be effective at eradicating them. The 650ML bottle is likely to last a very long time, given that only a few squirts were needed where the silverfish are spotted and I have not yet had to make a second application, many weeks later. The spray is easy to use—just give it a good shake and apply. It is described as low odour, and I didn’t notice any odour at all! If it has any odour, it is certainly unoffensive and is likely easily masked by other scents such as cooking or soaps that normally permeate rooms such as the kitchen and cloakroom. Pros: Immediate and effective silverfish control Also disinfects surfaces No odour that I could detect Long-lasting protection (up to 3 months per application) Cons: None observed so far Conclusion: Overall, I am very pleased with the Silverfish Killer Spray 650ML. With a quoted price of £12.99, this is not low cost, but it seems fair value given the quality supplied and the small amount needed. It is effective and easy to use. I recommend it to anyone dealing with a silverfish problem in their home.

Fantastic stuff
I can’t tell you how good this stuff is. I’ve never found anything before to actually kill silverfish other than the traps which are pretty useless. Thai stuff is fantastic. After I’ve cleaned (once a week) I spray this all around the skirting boards and over the next few days find the odd dead silverfish dotted around. The spray is quite strong and can get on your lungs so be sure to spray each room and leave for a while.

10/10
Sprayed twice throughout my house over 4 days and worked a treat, keep finding dead silver fish everywhere. Really Easy to use, smell is not too strong at all

good
it's good but it's like slow acting, I got the powder as well I prefer this as I feel it's powerful, although it's messy to use but it's fast acting.

So far so good.
Had this spray just for a few days but so far it has been very successful . So far I have not seen anymore silverfish since spraying just twice. Hoping this spray has done the trick.
