Product Information

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' killer 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 ingredient in Formula 'C' is the powerful insecticide cypermethrin, a broad spectrum insecticide so is also effective against a wide range of other flying and crawling insects.

Each 5-litre container is sufficient to treat an area of approx 100m2. 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.

Directions for use
Strip beds, and wash bedding on a high temperature.

Apply bed bug spray to affected areas, paying particular attention to the joints and between slats on frame beds and around headboards and the stapled edges of hessian covers on the underside of divans.

Formula 'C' can be lightly applied to mattresses (DO NOT SOAK), but must be left to dry completely before putting bedding back on. Inspect and treat around stitching and underneath any buttons.

Also treat bedside cabinets and the carpet and/or skirting boards around the bed.

Repeat bed bug treatment after 2 weeks.

To successfully eradicate a bed bug infestation, carrying out a treatment using a combination of insecticides delivers a better knockdown. So for the best results, Pest Expert Formula 'C' Spray should be used in combination with our other bug killing products such as Rentokil Insectrol Spray and Formula 'P' Bed Bug Powder and Formula 'P' Foggers or Smoke Bombs

When carrying out a bed bug treatment to a large area, we recommend using one of our Pressure Sprayers to enable an even distribution of the Formula 'D' insecticide and help achieve a thorough and professional application (see Related Products below).

Easy to apply and kills the bed bugs! Best thing is it leaves a residue which kills after the spray! Happy with the results!
