Rentokil Multi-Surface Insect Killer Pen

This is my go to fly killer: easy to use- just draw round the edges of windows, no need to spray the room so my kitchen is safe with pet food out. My windowsill ends up with dead flies that need regularly sweeping away. I can't recommend this product highly enough

What a joy, no more buzzing, no more horse fly's just a quick hoover up of insects. Not totally invisible, so keep it to the edges of the window, you do not need to go all round edge just the top corner. Remember this is an insecticide so use with caution you don't need it in your system so don't use to much.

Love this pen, it's so easy to use, just go round the edges of your window with the pen, once it liquid drys you cant see it, when the flies walk over it, they die within a few minutes. It's great, even works on big bluebottles

Does exactly what it says. Still have flies but as soon as they land on substance they fall to the floor. Just a case of hoovering them up.

This works a treat, although it attracted dust when applied.

Received this well before the said time and packed so well I had to use scissors to get through to the killer pen! It works ,flies landing on the right place which for some reason they do, drop like flies.

Very good

probably the best product ive bought, we had a new conservatory and were overrun with flies 24/7 ,ijust painted this clear pen around all the edges and job done flies land on it an die in a minute,
