Research Information — Seasonal Pests (Boxelder Bugs, Chinch Bugs, Clover & Spider Mites, Conifer Seed Bugs, Miller Moths, Springtails)
Spring and fall brings invasions of box elder bugs, army cutworms (which are the larvae of the miller moth) and other insects that come from lawns, trees and other plants. In many cases, lawn and tree experts can assist in treating problem areas. These insects are usually found feeding and nesting on plants, in the ground or in your lawn. But, when a change in season occurs, they seek shelter in cracks, crevices and voids to survive. By accident, they become pests inside structures and can become very annoying to deal with.
If any of these insects are seeking shelter where they are not wanted, PestRite can apply our $mart (Green) (Green) solution at each change in season.

Boxelder Bugs
Color: black with three red lines on the thorax
Size: 1/2 inch long as an adult
Feeding & Habits: Boxelder bugs feed on a variety of plants, but their favorite food is boxelder seed pods, which are found only on the female boxelder tree, and occasionally maple seeds. These bugs seldom develop in sufficient numbers to be a nuisance unless a female boxelder tree is in the neighborhood.
Chinch Bugs
Color: gray-black in color and covered with fine hair
Size: adults are approximately 3.5 mm long and 0.75 mm wide
Feeding & Habits: Mustard family plants, such as radish, canola, and mustard greens are particularly favored by false chinch bugs. spends the winter among winter annual mustards. Flixweed, a common weed associated with alfalfa fields and agricultural field margins, is an important winter host for this insect in eastern Colorado. When late winter/early spring temperatures warm sufficiently to allow development, eggs are laid around the base of plants.
Clover & Spider Mites
Color: reddish brown to dark green
Size: 1/30 inch long (smaller than a pinhead)
Feeding & Habits: feeds on grasses (heavy feeding gives a silvered appearance), clover, dandelion, shepherd's purse, strawberry and iris, to name a few. Most heavy outbreaks occur in early spring in well-fertilized lawns growing close to the house foundation on the sunny side of the house; although in the fall, thousands of clover mites may congregate on vegetation around homes and on foundation walls, crawling into protected places as cold weather arrives.
Conifer Bugs
Color: brownish on top. The upper (dorsal) side of the abdomen is yellow or light orange
Size: Adults are 3/4 inch
Feeding & Habits: feed and develop on seeds of various trees and shrubs. They prefer pines, Douglas-fir and other conifers but feed on developing seeds and fruits of a wide variety of plants, including dogwood and sumac.
Miller Moths
Color: grayish black
Size: 1-1½ inches Long
Feeding & Habits: The larva of this moth is known as the army cut worm which feeds on your tomato and other garden plants in the summer. Migrates from the plains to the mountains each year.
Springtails
Color: vary from white, gray, yellow, orange, metallic green, lavender to red with some being patterned or mottled
Size: minute, wingless insects about 1/16 to 1/8 inch
Feeding & Habits: They get their name from the ability to leap through the air three to four inches by means of a tail like mechanism tucked under the abdomen. Lives in soil, feeds on algae, fungi and decaying matter.
