Pest Expert Formula 'P+' is the only product on the UK market containing three active ingredients making it unrivalled in its ability to control and eradicate bed bug infestations, from minor to large and established.

In the UK, the strongest bed bug treatments available to the general public are usually based on Deltamethrin or Cypermethrin, such as the "Pest Expert Formula C+" or "Protector C" sprays. These are residual insecticides that leave a coating on surfaces to kill bugs that come into contact with it over several weeks. However, because many bed bug populations have developed a high resistance to these "pyrethroid" chemicals, many experts now recommend isopropyl alcohol-based sprays for an instant "contact kill" or the use of diatomaceous earth, a natural powder that dehydrates the insects. In 2026, the most effective professional-grade method remains Heat Treatment, where a room is heated to over 50°C for several hours, which is the only 100% effective way to kill all life stages, including eggs. For a "DIY" approach, a high-temperature steam cleaner is considered much more effective than most over-the-counter chemical sprays. If you have a significant infestation, the "strongest" solution is almost always to hire a professional pest control service that can use professional-only chemicals like Ficam W or Biopren which are not available for purchase by the general public in the UK.
