Not all insects are harmful to your garden; in fact, many are beneficial and are an important part of the ecosystem. Chemicals used to eliminate insects do not discriminate between the good bugs and the bad ones, so you can limit the damage done to beneficial insects and, at the same time, keep harmful chemicals out of the environment by practicing organic pest control.
Here are a few simple and effective ways to eliminate bugs and other pests naturally:
Handpicking: Insects can be handpicked from plants, and pests like potato bugs can easily be shaken from plants into a box. Use a butterfly net to capture white cabbageworm butterflies before they lay their eggs on your crucifers.
Traps: Slugs love to slurp beer from cans strategically placed in the garden, but don’t open the tops all the way lest the openings become two-way streets. Sticky traps hung in apple trees attract and trap apple maggot flies. Brush-on insect trap coating can be applied to small boards on stakes and used throughout the garden. Painting the boards a bright color will make them even more effective. Pheromone traps draw insects like Japanese beetles to their own hormonal scents and safely capture them in boxes away from prized roses and peonies.
Covers: Using lightweight floating covers on crops such as blueberries keeps those pesky birds, rabbits, and deer from eating you out of house and home. Of course, don’t install them until after pollination so that bees can do their job first.
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.
