CANKERWORM
Description: Also known as inchworms, this species is usually divided into spring and fall cankerworms. Each worm is roughly 1" long, but the spring cankerworms are green to reddish brown in color and have a yellow stripe on each side of their body, while the fall cankerworms are lighter green to brownish in color and have a dark middle stripe.
Attack mostly shade and fruit trees such as apple, elm and oak.
Damage, Symptoms: Cankerworms eat the leaves of the trees they infest stripping them of their foliage.
Tree/Shrub: Spray foliage with acephate, carbaryl, malathion or Bacillus thuringiensis when feeding or worms are first noticed in spring.
CARPENTER ANT
Description: Readily recognized by small necks and waists, troublesome species range in size from 1/8 to 1/2 inch long.
Habitat: Nests in the soil, various soil environments are conducive to ants.
Damage, Symptoms: In turf, mounds around nest openings frequently smother grass. Ants may also prevent good stands by destroying newly planted seed Some species attack flowers and shrubs A few, including fire and harvested ants, bite people.
Nonchemical: Keep foods in tightly sealed containers or in the refrigerator. Most ants prefer sweets and fats. Practice good sanitation. Avoid leaving dirty dishes or other food particles where they are accessible to ants. Caulk cracks and crevices in house foundation.
CARPENTER BEE
Description: Large bees that closely resemble bumble bees. About 1" in length they are heavy bodied and have a purple or greenish metallic sheen. Their bodies are covered with bright yellow or orange hair.
Habitat: Build nests in wood siding, decks, overhangs and other places where wood is exposed.
Damage, Symptoms: These bees do not eat the wood but build tunnels in it for nesting sites, leaving entry holes.
Chemical: Dust and spray entrances to nest with insecticide (carbaryl 5% dust). Do not plug entrance.
Nonchemical: In the fall, fill the holes and paint or varnish the entire wood surface.
CARPET BEETLE
Description: Small, oval-shaped bugs about 1/8" long. Most are black but they can also be any combination of white, yellow, orange or brown.
Habitat: Prefer dark areas that are often undisturbed such as closets or attics. They may also originate from animal or bird nests/carcasses that have found their way inside.
Damage, Symptoms: As their name implies, they feast on carpet and other items composed of animal fibers (fur, wool, leather, etc.). Undetected in homes, they can cause damage to bedding, floor covering, clothing and other articles.
Chemicals: Spray storage areas, edges of carpeting, baseboards, cracks and crevices with ready to use chlorpyrifos.
Nonchemical: Destroy all badly infested materials. If insulation is of plant or animal origin remove it from the structure. Check for any dead animal or bird carcasses that may be in wall voids, chimneys, or fireplace areas. Keep accumulation of lint to a minimum and vacuum thoroughly in areas where hair and other natural fibers gather. Remove all bird, insect and rodent nests in the fall before cool weather. Place cleaned or washed woolens in insect-free chests that are tightly sealed or in plastic bags. Dry cleaning and laundering kills these pests.
CENTIPEDE
Description: Vary from reddish-brown to grayish-yellow in color, flattened and elongated in size and have numerous legs which allow them to move quickly.
Habitat: They like moist spaces and can be found outdoors in wood piles, leaves, etc. Inside they are most often found in basements and other moist cracks and crevices.
Damage, Symptoms: Centipedes cause very little damage to man, other than being a nuisance in the home. They do, however, have poisonous glands and can bite, but this usually results in a swelling similar to a bee sting.
Nonchemical: Correct situations where moist habitats occur such as crawl spaces, poorly drained areas, and piles of trash, mulch, or compost. Remove indoors by vacuuming.
CHIGGER, JIGGER, RED BUG
Description: Oval, bright yellow-range; size of a pin- head or smaller.
Habitat: Most numerous east of the Rocky Mountains, chiggers invade lawns during the summer. Microscopic larvae attack man.
Damage, Symptoms: Poisonous bite irritates and causes scattered red blotching of skin usually takes place under tight areas of clothing Intense itching may continue for a week or more.
Chemical: Treat lawns, roadsides, and areas not mowed. For personal protection, a repellent such as DEET will prevent attack.
Nonchemical: Eliminate or mow breeding sites, especially briars, weeds, and other thick vegetation where there is an abundance of moisture and shade. Wear protective clothing such as a long-sleeved shirt and trousers, shoes, and socks. Tuck pant legs into boots or socks. Avoid sitting on the ground either in the lawn or brushy areas. Take a warm soapy shower or bath immediately after returning from any infested areas.
CHINCH BUG
Description: Full-grown nymphs and adults are red-black; adults have white wings folded over the back and are 1/6 inch long Nymphs are smaller and bright red bluegrass lawns.
Habitat: Infesting lawns from spring until frost, chinch bugs prefer sunny areas; thrive during hot dry weather, and damage St Augustine, bentgrass and bluegrass lawns.
Damage, Symptoms: Bleached, yellow areas of grass which rapidly turn brown are often caused by chinch bugs which suck the juices from plants. The bugs, though tiny, can be found in thatch or at the bases of infested grass.
Lawn: Spray infested areas with chlorpyrifos where chinch bugs are present.
CLOTHES MOTHS
Description: Small, yellowish to slightly gold-colored with narrow wings.
Habitat: Indoors in dark areas. They are not attracted to light and tend to hide when disturbed.
Damage, Symptoms: Feed on wool and fabrics, especially those that have been neglected with stains on them. Clothes moth larvae also cause a lot of damage as undetected caterpillars under woven rugs.
Chemical: Spray storage areas, edges of carpeting, baseboards, cracks and crevices with ready to use chlorpyrifos or diazinon.
Nonchemical: Destroy all badly infested materials. If insulation is of plant or animal origin remove it from the structure. Check for any dead animal or bird carcasses that may be in wall voids, chimneys, or fireplace areas. Keep accumulation of lint to a minimum and vacuum thoroughly in areas where hair and other natural fibers gather. Remove all bird, insect and rodent nests in the fall before cool weather. Place cleaned or washed woolens in insect-free chests that are tightly sealed or in plastic bags. Dry cleaning and laundering kills these pests.
CLOVER MITE
Description: Only 1/30 inch long (smaller than a pinhead) the adult clover mite is dark red and has eight legs, the frontal pair long and extending forward from the body.
Habitat: Although they feed on Covers and grasses, these mites lay eggs and return to molt in trees or cracks and crevices of building walls Heavy infestations appear in heavily fertilized lawns and may invade homes during the spring.
Damage, Symptoms: Sucking of plant juices brings a bleached or silvered book to blades of grass.
Chemical: Apply dicofol spray to outside foundation and adjacent 1 ft. of soil. Indoors: Spray with pyrethroid.
Nonchemical: Eliminate grass and other vegetation in a 1 ft. band all the way around the house. Also make sure window and door seams are properly caulked and sealed to prevent entry by the mites. Indoors: Mites can be removed by vacuuming.
COCKROACH (German, Brown-banded, American, and Oriental)
Description: Flattened oval shape, spiny legs and long antennae. Colors range according to species but most are reddish to dark brown or black.
Habitat: They are night-active insects who like damp places. The Oriental and German species are most common in households residing in basements, crawl spaces, bathrooms and places where there is food.
Damage, Symptoms: They can contaminate food and secrete an unpleasant odor. Many people also develop allergies to cockroaches.
Chemical: Spray roach runways and hiding places with either chlorpyrifos, propoxur, boric acid, or hydroprene (all ready to use sprays). Treat under sink, refrigerator, cabinets, on baseboards, etc. Treatment throughout home may be needed to control brown-banded roaches. May be supplemented with boric acid applied into out-of-sight and out-of-reach voids under cabinets and appliances.
Nonchemical: Practice proper sanitation by keeping food properly sealed or stored in the refrigerator. Keep trash covered. Do not allow dirty dishes to accumulate. Clean frequently under refrigerators and stoves where food particles may accumulate. Eliminate hiding places such as piles of newspapers, boxes and papers. Caulk cracks and crevices. Do not leave pet food out overnight.
COLORADO POTATO BEETLE
Description: About 3/8" long with black and yellow stripes on its back. The head is tannish-orange and has black markings.
Habitat: Lives primarily off of eggplant, potatoes and tomatoes.
Damage, Symptoms: Destroys the leaves of potatoes and eats the fruit of eggplant and tomatoes.
Vegetable: Apply carbarylor rotenone as needed. Insects usually present only in late May and June. Handpick larvae and adults off of plants.
CRICKET
Description: Most species have dark, rounded, grasshopper-like bodies and prominent antennae Size ranges from 1/2 to 1-1/2 inches long Females have a prominent swordlike ovipositor Mole crickets are light brown with lighter underbody sometimes tinged with green They have short stout forelegs, shovel shaped feet and large, beady eyes.
Habitat: By day they hide under boards, low- lying foliage or trash: coming out at night to feed. They have a varied diet including flowers and tender growth of many garden plants Mole crickets live in turf.
Damage, Symptoms: Presence of crickets in the garden, under leaves of cabbage, cucumbers, and other crops indicates potential for damage. Presence of adult or immature mole cricket in grass is a sign they might damage turf Mole crickets burrow in the ground, feeding on grass roots, uprooting seedlings and causing soil to dry out quickly.
Nonchemical: Cracks and crevices around windows, doors, and in the foundation should be properly sealed and caulked. Indoors: Remove crickets by vacuuming. House lights attract both field and house crickets. Keep garbage cans clean and empty frequently. Keep firewood at least 1-2 feet away from the foundation. Apply a 6-inch band of ashes around the wood pile. Eliminate sources of moisture by fixing leaky pipes and modifying damp areas.
CUTWORM
Description: Soft bodied, dull gray green, brown or black caterpillars. some species are spotted, others striped. Size varies from 1-1/4 to 2 inches long They curl up tightly when disturbed Adults are gray-brown moths readily attracted to lights at night.
Habitat: All turfgrasses, dichondra, several flower varieties and most vegetables, especially early-season pepper, tomato, peas, beans and Cole crops, are subject to attack. Most species hide in the soil or under trash during the day and come out at night.
Damage, Symptoms: Some feed on leaves, buds or fruit while others feed on underground portions of plants: plant cut off at or below soil surface is sure sign.
Vegetable: They attack most garden crops. For cutowrms, attach collars of paper, aluminum foil or metal at planting for small numbers of plants, or apply insecticide (carbaryl or rotenone) to base of plants at first sign of cutting.
