Biological
Pest Control: Releasing beneficial bugs
into your garden to feed on bad bugs is a fine way of eliminating pests.
Ladybugs love aphids, and certain wasps lay eggs on the eggs of other
insects, such as cutworms and cornborers; when the wasp eggs hatch, they
feed on the pest eggs. The bacteria Bacillus thuringiensis (Bt) is found
in spray form and is used to control cabbageworms and their cousins.
Botanical Pest Control: Natural insecticides made from plants like the
pyrethrum daisy (Tanacetum coccineum) are used very effectively and are
a major force in the bad bug patrol. Pyrethrum, rotenone, and sabadilla
are a few of these botanicals, which disperse quickly and do not leave
residues.
