Miller moths exist in large numbers in Colorado and other mountainous regions, and feed on plants and garden flowers. They can be a nuisance in homes, where they seek out windows or other sources of natural light and warmth. In their caterpillar stages they can also damage crops and other plant life. Miller moths emit a slightly unpleasant odor, especially after they die, and this can attract other insects to the home, leading to an insect infestation of larger proportions. You definitely do not want these moths in your house!
Miller Moth Identification and Life Cycle
Miller moths are gray or light brown, and measure approximately 1.5 to 2 inches in wing-span. They are attracted to thick and lush vegetation, including lawns, gardens, wheat, and alfalfa. They are most destructive in their caterpillar stage, as they tend to feed more often in this stage than in any other life cycle stage. Caterpillars generally emerge in early spring, and immediately begin satisfying their ravenous and destructive appetites. In their adult stages miller moths may also be a nuisance in the home, although they do not feed on furniture or cloth, as many other moths do.
The Best Ways to Control Miller Moths
If you are trying to combat a miller moth infestation, consider releasing natural predators into the area to combat the pest. Garden beetles will search for and consume miller moths, especially during the moths’ caterpillar stage, and birds and bats will also combat the moths effectively. You can attract birds by planting certain pollinating flowers, and can increase the bat population in your area by building a bat house.
To prevent miller moths from invading your home, be sure to check all windows, doors, and walls to make sure that they are well sealed and tightly shut. If miller moths are already in your home, vacuum them up as soon as you spot them. Insecticides are not known to be helpful in reducing miller moth numbers once the moths have already infested an area. However, insecticides may be helpful in deterring them. Always use caution when applying insecticides or pesticides inside the home.
