This tropical ant was found 1982 in Halle-Neustadt (kindergarden), 1985 in Rostock (bakery), 1994 in Hamburg (dwelling-house), 1996 in Salzgitter-Lichtenberg (dwelling-house) and since 1994 also observed and controlled in Berlin (dwelling-houses).Important exterior characteristics are: size 1.3–1.5 mm (worker), 2.3–2.5 mm (female and male), petiolus its not scale-like, gaster with 4 from dorsal visible segments. Colour: caput blackbrown to black; gaster is cream to brownyellow (worker), brownish (female), blackbrown to black (male), coloured. Their behaviour distinguished them fromMonomorium pharaonis: they run very quickly and restlessly, “ant roads” are not longer than 6–8 hours existent.Preferred food: lying about food, dead flies and cockroaches, cake, milk, sweets. This species was fed in laboratory with mixture from yolkpowder, biskuitmeal and honey, dead insects.The inquiry of attack-locality results with pig-lever or saturated sugar-solution. Baits-boxes were placed on the attack-locality directly. It was distinctly, that Maxforce-Bait (Hydramethylnon) was visited middling. Baits with a mixture of peanut-fat and boric or of yolkpowder, honey and boric were attractive about a longer time and effective in the control. T. melanocephalum was introduced likely with tropical flowers and fruits, sweets or baking from subtropical-tropical region in dwelling houses.
