Massive stars, supernovae, and kilonovae are among the most luminousradiation sources in the universe. Observations usually show near- tomid-infrared (NIR--MIR, $\lambda\sim 1-5~\mu$m) emission excess from H\,{\scii} regions around young massive star clusters (YMSCs). Early phaseobservations in optical to NIR wavelengths of type Ia supernovae also revealunusual properties of dust extinction and dust polarization. The popularexplanation for such NIR-MIR excess and unusual dust properties is thepredominance of small grains (size $a\lesssim 0.05~\mu$m) relative to largegrains ($a\gtrsim 0.1~\mu$m) in the local environment of these strong radiationsources. The question of why small grains are predominant in these environmentsremains a mystery. Here we report a new mechanism of dust destruction based oncentrifugal stress within extremely fast-rotating grains spun-up by radiativetorques, which we term the RAdiative Torque Disruption (RATD) mechanism. Wefind that RATD can disrupt large grains located within a distance of $\sim 1$pc from a massive star of luminosity $L\sim 10^{4}L_{\odot}$ or a supernova.This effect increases the abundance of small grains relative to large grainsand successfully reproduces the observed NIR-MIR excess and anomalous dustextinction/polarization. We apply the RATD mechanism for kilonovae and findthat dust within $\sim$ 0.1 pc would be dominated by small grains. Small grainsproduced by RATD can also explain the steep far-UV rise in extinction curvestoward starburst and high redshift galaxies, and the decrease of the escapefraction of Ly$\alpha$ photons from H\,{\sc ii} regions surrounding YMSCs.
