Product Information

Pest Expert Formula ‘P+’ Ultimate Bed Bug Killer is a maximum-strength, specialised insecticide concentrate ideal for controlling bed bug infestations.

The unique professional grade formulation has only recently been approved for amateur use. Containing three powerful active  ingredients: Tetramethrin (0.9%), Permethrin (6%) and  PBO it provides both a rapid knockdown and long-lasting residual. This exclusive combination of actives cannot be found anywhere else and makes Formula 'P+' the strongest bed bug-killing insecticide available on the amateur market. A 100ml concentrate bottle will dilute to treat 100 square metres.

Formula ‘P+’ attacks the bed bug’s nervous system, working quickly upon contact and/or when ingested to eradicate even large bed bug infestations.

A 100ml bottle will dilute to treat 100 square metres.

Directions for use

Shake the bottle before use. Dilute the product as instructed below and use immediately. Spray on insect-infested areas, applying to cracks and crevices, wall-floor junctions and in all places where bed bugs may be harbouring. After use, avoid treated surfaces.

Flying insects: Dilute 25ml of the product in 5L of water.

Crawling insects: Dilute 50ml of the product in 5L of water for use on non-porous surfaces (wood, glass, ceramics), and 75ml of the product in 5L of water for use on porous surfaces (carpets, concrete).


Formula ‘P+’ is best administered with a 5L Pressure Sprayer for a more thorough and even coverage (see related products below).

For a comprehensive treatment, use alongside Formula ‘P’ Bed Bug Powder and Formula ‘P’ Foggers or Smoke Bombs.

Utterly amazed by the results after using this concentrate spray. This is by a long way the strongest and most effective bed bug spray I've used.
