We report SIMBA 1.2 mm dust continuum observations of the environments of eight methanol maser sources, all discovered during spatially fully-sampled, untargeted surveys of the galactic plane. We summarise our search for possible associations of the masers with IR sources (IRAS and MSX) and find that it is not always possible to make definite associations. A preliminary characterisation of the IR sources found in the maser neighbourhood is given according to their position in the [60–25]–[25–12] colour-colour diagram.
Key words: masers / stars: formation / infrared: stars / circumstellar matter / HII regions / stars: evolution
