Pest Expert Formula C+ Advanced Silverfish Killer Spray is the new and improved formulation of our top selling product, Formula C. The advanced triple action, ready-to-use silverfish killer spray is fast acting, with a long-lasting residue to maintain silverfish control for up to 12 weeks.

The unique combination of active ingredients make Formula C+ the most powerful silverfish spray available to the amateur market and the perfect product for quick and effective eradication of any level of silverfish infestation.

As market leaders, Pest Expert’s latest formula includes two additional active ingredients. The first is pyriproxyfen, an innovative insect growth regulator that works by stalling the transition of the silverfish life-cycle from juvenile to adult, leading to the inability of the silverfish to reproduce resulting in no increase in numbers. The second new addition to the formula is chrysanthemum cinerariaefolium extract, a 100% natural pyrethrum, which when combined with the existing cypermethrin insecticide results in a synergistic effect, delivering an even faster knockdown and a more powerful longer-lasting residue to maintain control of the silverfish full life-cycle. 

Being approved for both professional and amateur use, Formula C+ is a professional grade insecticide that can be safely used in the home. It is easy-to-use and can be applied directly to the kitchen and bathroom due it being water-based and non-staining, so will not cause any damage to household furnishings. Being low-odour and free from solvents, Pest Expert Formula C+ is safe to use in homes where there are children and/or pets, providing the instructions are followed and they are kept out of the room for 2-3 hours follow the treatment.

Pest Expert Formula C+ Advanced 5L now offers an increased coverage of up to 250 sq meters. Due to the potency, one application should be enough to successfully eradicate a silverfish infestation, however, in instances of heavy infestation, a second application may be required. 

To achieve a thorough and professional application, we provide a free trigger hose sprayer with the 5 Litre bottle (one per order).
