A swatter has a handle, and a flat swatting blade which is fast with the handle. The blade is provided with openings which are uniformly distributed over the blade. Two sets of impaling projections are mounted on one of the major surfaces of the blade. The projections of the two sets are of different length and are uniformly distributed over the blade and among each other. Neighboring projections of each set are spaced from one another by distances which are so large that essentially no squashing of an insect would occur were the insect to be impaled by more than one projection of a set.
