Product information

Formula 'C+' Spray 1 Litre

As market leaders, our latest innovative formulation now incorporates two additional active ingredients. The first is pyriproxyfen, a ground-breaking insect growth regulator that cleverly works by halting the progression of the bed bug's life-cycle development from juvenile to adult, resulting in an inability for the bed bug to reproduce and therefore ensuring there is no increase in numbers. ​​​​​​​

The second addition is chrysanthemum cinerariaefolium extract, a natural pyrethrum, which when combined with the existing concentration of cypermethrin has a synergistic effect, helping to deliver an even faster knockdown and longer-lasting residual for ongoing control of al lifecycle stages.  

Pest Expert Formula 'C+' is a highly-effective bed bug killer spray that delivers a rapid knockdown and helps maintain bed bug control. The invisible residue not only kills on contact but also remains effective for a number of weeks, offering longer-lasting protection.

Formula 'C+' Bed Bug Spray is water-based so is safe for direct application to frames, mattresses, bedding and carpets and will not cause them any damage.

Formula 'C' is low-odour and free from solvents, so it is perfectly suitable for bed bug treatment in all contexts, including hotels and B&Bs, hospitals and care homes, and households with children and/or pets, provided they are kept out of the area being treated until all surfaces are dry (2-3 hours).

The active ingredients in Formula 'C+' are all broad spectrum insecticides that are effective against a wide range of flying and crawling insects.

Each 1-litre trigger spray is sufficient to treat an area of approx.  50m2. As bed bugs can be difficult to eradicate, to successfully control an infestation we would recommend carrying out a repeat treatment approx 2 weeks after the initial treatment. For particularly heavy infestations then several applications may be necessary.

Formula 'P' Powder

Formula 'P' Bed Bug Killer Powder is a highly effective bed bug treatment powder that eradicates all the lifecycle stages of bed bugs. The active ingredient, permethrin, is a powerful broad-spectrum insecticide that provides lasting control against bed bugs. The easy-to-use puffer pack makes for easy application to treatment areas and the powder based delivery method is ideally suited for use in areas close to electrical items and sockets, where a spray wouldn't be useable. The powder is an essential component of any comprehensive bed bug treatment.

Directions for use

In order to achieve swift results and the greatest level of control, we would recommend using the powder in conjunction with Pest Expert Formula ‘C+’ Bed Bug Spray and Formula ‘P’ Foggers.
