  We obtain constraints on first- and second-generation scalar leptoquarks
using the available data on dilepton (Drell-Yan) and monojet searches at the
CERN Large Hadron Collider. Assuming that the leptoquark interactions respect
the Standard Model gauge symmetries as well as lepton and baryon numbers, we
show that the study of dilepton production enlarges the exclusion region on the
mass and coupling plane with respect to the pair production searches for
first-generation leptoquarks. Moreover, the monojet channel leads to a larger
excluded parameter region for moderate to large values of the leptoquark Yukawa
coupling than the presently available experimental results.
