A device for attracting and inducing blood-feeding biting flies to land on it and to kill them, comprising a tubular body defining a central axis and a height H defined in the length of said central axis, said tubular body comprising a wall parallel to said central axis and defining lateral cross sections perpendicular to said central axis, the device being characterized in that it further comprises: - said tubular body has a first opening defining a first rim and a second opening defining a second rim; - said first rim and second rim are connected by at least a portion of said wall; - said wall has an outer surface and an inner surface; - said outer surface reflects or scatters less than 5% of illuminating light incident on said outer surface for wavelengths between 600 nm and 700 nm and peak reflectance less than 40% on said outer surface for wavelengths between 450 nm and 500 nm; - the color of said outer surface or said inner surface is blue or is colourless, said blue colour being defined in the 1960 CIE colour diagram by a x value defined between 0.145 and 0.225 and a y value defined between 0.185 and 0.305, colourless being defined in the 1960 CIE colour diagram by a x value defined between 0.210 and 0.420 and a y value defined between 0.220 and 0.430; - said outer surface comprising at least a portion incorporating a substance for retaining and killing insects on or near to said outer surface 6a; - said inner surface has a lower reflectivity than the reflectivity of said outer surface, this reflectivity being defined as the fraction of reflected light of the illuminating light incident on said inner surface, for wavelengths between 360 nm and 700 nm, said reflectivity being defined for reflected and/or scattered light by said inner surface; - the value of said reflectivity of said inner surface is lower than 20%, preferably lower than 10%, even more preferably lower than 5%, - the lateral dimension of the tubular body, defined in any plane perpendicular to said central axis, is greater than said height H. - said tubular body has a first opening defining a first rim and a second opening defining a second rim; - said first rim and second rim are connected by at least a portion of said wall; - said wall has an outer surface and an inner surface; - said outer surface reflects or scatters less than 5% of illuminating light incident on said outer surface for wavelengths between 600 nm and 700 nm and peak reflectance less than 40% on said outer surface for wavelengths between 450 nm and 500 nm; - the color of said outer surface or said inner surface is blue or is colourless, said blue colour being defined in the 1960 CIE colour diagram by a x value defined between 0.145 and 0.225 and a y value defined between 0.185 and 0.305, colourless being defined in the 1960 CIE colour diagram by a x value defined between 0.210 and 0.420 and a y value defined between 0.220 and 0.430; - said outer surface comprising at least a portion incorporating a substance for retaining and killing insects on or near to said outer surface 6a; - said inner surface has a lower reflectivity than the reflectivity of said outer surface, this reflectivity being defined as the fraction of reflected light of the illuminating light incident on said inner surface, for wavelengths between 360 nm and 700 nm, said reflectivity being defined for reflected and/or scattered light by said inner surface; - the value of said reflectivity of said inner surface is lower than 20%, preferably lower than 10%, even more preferably lower than 5%, - the lateral dimension of the tubular body, defined in any plane perpendicular to said central axis, is greater than said height H.
