AB  - The goal of this thesis is to probe astrophysical transients as neutrino sources. Bright flares from enhanced accretion onto supermassive black holes (SMBHs) were reported to be correlated with IceCube's high-energy (>100 TeV) neutrino alerts. They are characterized by bright, transient infrared emission, called dust echos. For the first time, this work probes the general population of accretion flares using the full IceCube muon neutrino sample with a stacking analysis. The non-detection constrains their contribution to the diffuse neutrino flux to below around 7.1
