Moth Stop Carpet Moth Killer and Freshener Spray 500ml 5 "Works well" Mrs Cooper 30 July 2020 We were plagued with Silverfish but now, a spray of this product keeps them all at bay. I spray each room about once every three months and rarely see the silverfish now. It does not get rid of them completely as I do see the odd one but that is usually about the time I need to be spraying again. I do recommend this product,. Its the only product I have found that works. even the pest control companies could not rid me of the Silver fish . But Thank you Lakeland you have.
