Do you mean biological insecticide or botanical insecticide? the terms are close, but they describe two different things.
A botanical insecticide is one that is obtained from a botanical (plant) source - examples of this are Neem oil, Nicotine, Citronella, Tagetes extract etc. The active ingredient in the insecticide may be toxic (as in the case of Neem and Nicotine), or may only offer deterrent value such as Citronella oil (for flies and mosquito's).
A biological insecticide (also called biological control) is where a insect, fungus or virus is bred and released into the wild (or onto a target species) in order to kill the other species. In most cases the bred control species is a natural predator of the pest insect. A good example of this is breeding Ladybirds and releasing them into the garden, the adult as well as the larval stage predate on aphids and mealy bugs.

No insecticide kills spiders and spares praying mantises. Spiders number among the world's arachnids, along with mites, scorpions and ticks, whereas praying mantises, as insects, may be as vulnerable as arachnids even to such botanical insecticides as nicotine sulfate and pyrethrum. Spider control by botanical or chemical means requires a product that is categorized as an acaricide or as an arachnicide.
