Periodicity in the 6.7GHz methanol maser sources is a rare phenomenon discovered during long-term monitoring programs. Understanding underlying processes leading to periodic variability might give insight of the physical processes in high-mass starforming regions. We aim to identify and describe new periodic methanol masers. The observations were obtained with the Torun 32m antenna. Analysis of time series was conducted using well-proven statistical methods. Additionally, NEOWISE data were used to search for infra-red and maser fluxes correlation. We found two new periodic sources: G45.804-0.356 and G49.043-1.079 with periods of 416.9 and 469.3 days, respectively. For G49.043-1.079, infra-red variability is simultaneous with methanol flares. A most likely cause of periodicity in G49.043-1.079 is modulated accretion, while for G45.804-0.356 cannot be explained with the available data and further research is needed.
