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.
Review: Really works even on Spiders which isn't mentioned on the tin! - Used this product for years now to spray windows and doors to deter Spiders, works a treat! Used to be easy to get hold off on stores like B&Q however it seems to have disappeared from shops now but was r Elieved to find it available from this seller on desertcart and although the price has increased from what I used to be able to get it for its still worth it for a house full of arachnophobes and with free delivery I was happy :) of you have white uPVC it will stain it eventually I tend to try and stick to the inside of the frame, but with a bit of elbow grease the stains do come off but obviously y then the product is gone so tend to wait till after spider season to clean off properly. Normal window cleaning does not effect the product it lasts a few months I tend to respray every 2-3 months. Arrived on time with full tracking right up to the knock on the door :)

### ⭐⭐⭐⭐ 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.
