Yes. It is the plural of insecticide, as in, "There are various insecticides from which to choose."
Some insecticides are just as toxic to humans as they are to insects. Typically, it just takes a larger exposure to affect a human. However, some insecticides can be toxic even in small quantities. Insecticides such as malathion or diazinon would be harmful to humans in much smaller quantities than insecticides derived from soaps or orange peels.
Insecticides contain chemical compounds known to be lethal to the creatures identified in the product information. Refer to the related link below for a Wikipedia article on insecticides.
