Complementary primers can cause PCR artifacts, especially in control lanes (without template). The primers anneal to each other and extend, sometimes producing large amount of products. The extra bands that appear in the control lane usually will disappear in the presence of competing template. Depending on the degree of complementarity, raising the annealing temperature may help if there are extra bands in other lanes.
