An insect killing device including rigid outer and inner tubes assembled to be slidably and telescopically engaged, and having a pliant, limber elastic cord extended therethrough. The cord is interconnected at its respective proximal and distal ends only to a gripping pull knob and substantially flat insect-impact element. The pull knob is connected to the inner tube proximal end and is larger than the outer tubes inner diameter to prevent accidental disassembly thereof. Sighting an insect on a surface, user grasps the outer tube by one hand, and with the other hand retracts the knob along with the inner tube and cord, drawing the impact element toward the inner tube distal end. On release the stretched cord and inner tube drive the impact element against the insect. The pliant nature of the cord affords an unrestricted twisting motion of the impact element so as to align with an impact surface.
