2 X Rentokil PSM73 Multi Surface Fly and Ant Killer Pen

I have used fly pen for many years. They are brilliant, expensive but worth the out lay. Clean windows and glass ware, light fittings, mirrors put on a line of the fly pen, you won't be disappointed.

Excellent product. Used on the top and bottom edges of the windows it is really effective. No need to reapply for a few weeks as it still works well.

I think this product is amazing, you cant see it when in the window ,and it kills all flying insects .just the job would highly recommend 👍

Seems to work ok.

Used these in the conservatory as I was plagued with flies in the summer, just 'draw' around each window frame with the 'felt-tip' pen, just one application lasted all summer, each morning there were nasty dead flies laying on the window sill. One problem is that any insect,eg, ladybirds/bees, that come in contact with the window frames also die, I do my best to help friendly insects escape by rescuing them before they can be harmed.

Previously bought stick ons for the Windows, but the flies stay there so not pleasant to look at, the fly pens are good, and work well.

I've been using these for years and have recommended it to so many friends. No nasty smell like you get from aerosols . You be surprised especially in summer how many wee days you find on your window sill

Great product. No spraying involved so really safe for pets and aquariums. A little on the window is effective.
