Habitat
changes
– moving old tires and other catch basins cuts down on the number
of mosquitoes breeding in your area. Such simple changes of
the physical habitat can control many pests. |
Natural
predators –
introduce and encourage the types of animals that naturally
gobble up pests. Those toads, garter snakes, and ladybugs are
natural predators on insect pests. |
Mechanical
prevention – remove
eggs, larvae, cocoons, and adult insects by hand. |
Timing
– avoid planting and harvesting when insects are most abundant
and damaging. |
Resistant
plants –
buy plants that are resistant and free of pests and diseases. |
Mixed
plantings
– areas with a variety of plant types are less susceptible to
insect damage. |
Growing
conditions –
plants are more resistant to pests and diseases if grown under
their favored conditions of light, moisture, etc. |
Insect
hormones
– use insect hormones that prevent the insect from growing into
a sexually mature adult. |
Natural
pathogens and parasites –
introduce bacteria, viruses, and parasites that kill pests but
won’t harm other types of animals. |
Chemicals
– use synthetic pesticides with a short life, only as needed,
and applied at the correct part of the insect’s life cycle. |
Managing
pond or lake vegetation and that growing along rivers and streams
requires special treatment. For information, contact your county
WSU Cooperative Extension. |
