CONSTRAIN. For the control of all insect pests in museums, archives, historic houses etc.

Constrain is a new generation water-based insecticide spray with a neutral pH, for the control of a wide range of insect pests (wood borers, clothes moths, carpet beetles, biscuit beetles, silverfish and book lice etc.) found in historic and scientific collections.

Constrain has been tested by the Central Science laboratory (MAFF) for its efficacy as a residual insecticide and found to compare very favourably with permethrin or bendiocarb wettable powders, or encapsulated chlorpyriphos’ (Pinniger et al 1994) (Morgan et al 1993). It has also been evaluated for any potential for damaging delicate materials, and found to have no noticeable effect on all the materials tested including textiles, paper, wood, metals etc. It did not change the appearance of colours or textures of the materials tested, did not encourage metallic corrosion and was rapidly absorbed into porous objects. However, it is advisable to test a small amount on an inconspicuous area first.

Constrain is a colourless, odourless, insecticide that comes in a ready-to-use trigger spray. It is cleared for amateur use as an insecticide under the Control of Pesticides Regulations 1984.
