Product Information

Formula ‘P’ Silverfish Powder is a powerful insecticidal powder that kills all the lifecycle stages of silverfish. It contains the active ingredient permethrin (0.5% w/w), a broad-spectrum insecticide which is also effective against an extensive range of other crawling and flying insects. The powder is ideally suited for application to areas where a spray would not be suitable, such as areas near electrical appliances and power sockets.

This 300g pack contains twice as much powder as Rentokil Insectrol!

Directions for use

Formula ‘P’ Powder should be applied evenly to affected surfaces. A more liberal application should be applied to areas where silverfish are harbouring. In high-traffic areas where the powder could be disturbed, or any areas accessible to children or pets, the powder should be left for approximately 30 minutes before being vacuumed up. In inaccessible areas the powder can be left for longer for more effective control.


If the powder cannot be left down, treatment using Formula ‘P’ Powder should be followed with the use of our Pest Expert Formula 'C+' Advanced Silverfish Spray to provide longer-lasting residual protection, and Pest Expert Formula 'P+' Fogger to fumigate the space being treated.

We have now included the Formula 'P' Powder in our best-selling silverfish treatment kits, which previously contained Rentokil Insectrol. Our Kits are made up of the best silverfish killing products to enable you to carry out a comprehensive treatment, ensuring total silverfish control at great value for money.
