The BLUESTAR® Cimex blood revealing reagent makes it easy to spot the hemoglobin contained in bed bug excrement and to trace it back to the source of infestation.

Ready in one minute (just dissolve the tablets in water). Simply spray BLUESTAR® Cimex on suspected areas, and the product will instantly turn luminescent blue when it comes into contact with the slightest trace of hemoglobin. This reaction is easily seen in the dark by the naked eye.
