Review: BRILLIANT FLY REPELLANT - This is the best stuff. Thank goodness it is back in stock. We have a problem with flies living in the double glazing frames. A good spray of this all round keeps them away for six months or more. Flies just don`t come back. Highly recommended. Would also work for other flying bugs.

### ⭐⭐⭐⭐ Death to all creepy crawlies-hooray !
*by D***Y on 12 January 2026*

Not had the ant killer, but the insect one, Same difference we guess. Use it each year in our orangery as it attracts wood lice in there, did the trick after just one spray! No overpowering spray, lasted all winter up to now. Good value for money too.
