Crawling Insects Pest ID
like Ants, Cockroaches, Beetles, Earwigs, Millipedes, Centipedes, and more prior to rendering any treatment in Southern Nevada. A properly identified Crawling Insect will result in properly executed treatment, with little to no future ongoing pest activity. Below are examples of many Cockroaches that are available throughout the area. Crawling Insect are a very select group of insects and require a specialized treatment process. Please consult with a professional pest control company prior to making your own treatment.
Acrobat Ant Cremastogaster Lineolata are small blackish red ants 2 to 3 mm (1/8″ long) recognizable because of their heart shaped lower segment that will be raised above the thorax or head when frightened. Like a carpenter ant the acrobat ant may be found in rotten wood, or tree cavities. You may also find a colony under organic tree matter, rocks, or anywhere soil would be kept moist.
Linepithema Humile or Iridomyrmex Humilis are small blackish brown ants 1.6 mm (1/16″ long) first identified in Buenos Aires, Argentina in 1866 and have spread to many parts of the world like Africa, United States, and Australia. These ants can be found in cracks and crevices in the ground or concrete walls. One colony may contain several reproductive queens (8 queens for every 1000 workers) which maybe found foraging around with the worker ants for food. Control of this ant maybe difficult because of the number of queens found in one colony and the ants ability to mingle with neighboring colonies without being attached by other Argentine ants, using a reputable pest control company is suggested.
Big Headed Ant Pheidole Megacephala are reddish brown to light brown ants 7mm (1/8 to 1/4″ long) that feed primarily on a wide variety of protein food like dead insects, garbage but maybe partial to sweets. These ants maybe found along the Gulf Coast of the United States, and nest outside in the soil under rocks, wood, and landscape timbers.
Camponotus Pennsylvanicus are large black ants 1/4 to 1″ long and indigenous to many parts of the United States and prefer dead, damp wood in which to build nests. Unlike termites, the carpenter ant will burrow into soft wood and setup a colony -the wood left behind by the carpenter ants damage looks similar to a saw dust or frass material. When activity is found, immediate response is needed to prevent structural damage and yearly preventative pesticide applications may be needed to eliminate future infestations. Treatment plans for homeowners includes replacing and/or removing damaged wood and placing ant bait in strategic places. Calling a local reputable pest control provider maybe needed when a baiting does not eliminate a nest.
Cornfield Ants Lasius Alienus are small brown ants 1/10 to 1/4″ long and found in lawns, fields, and cracks in driveways, patio blocks, or beneath rocks. Evidence of ant activity can be viewed around injured corn plants by the anthills formed around the plants. Cornfield ants do not generally enter a structure, but can occasionally enter looking for sweets.
Pavement Ants Tetramorium Caespitum are small dark brown ants 1/10 to 1/16″ long and found in several parts of the North America as far north as Canada or as far south as Florida. A colony may contain several thousand workers and multiple queens in one location. The Pavement Ant earns its name from building a nest in the crack or crevices of sidewalk, patio blocks, foundations of structures, and driveways. Activity found on the interior of a structure usually use baseboards and plumbing as a highway which ants will follow because of pheromones left behind from prior ant activity. Generally, baiting is a preferred choice of treatment for a homeowner where ant activity is heaviest. Baiting Pavement Ants is a common way to eliminate activity, sanitation may also play a factor in keeping Pavement Ants at bay on the interior of a structure.
Pharaoh Ants Monomorium Pharaonis are yellow or light brown with a brown abdomen 1/16″ long and can be found in any structural dwelling. Pharaoh Ants feed on sweets, dead insects, and are capable of transmitting diseases when found in sterile environments (hospitals, and nursing homes), and favor warm structures with little or no disturbances. Pharaoh Ants can be very difficult to control because of the length of lifespan (45 days from egg to adult) and the number of eggs a queen lays (typically 400 eggs) with several queens in one colony. Pharaoh Ants are recognizable by the 2 nodes found on their petiole, and the thorax is spineless. Baiting is the only recommending treatment plan for homeowners, and preventative exterior treatments maybe applied around the exterior of the structure after activity ceases.
Thief Ants Solenopsis Molesta are brownish in color 1/16″ long and maybe confused with the Pharaoh Ant. Thief Ants can be found on the interior and exterior of structures and often live in close relationship to larger ants. Thief Ants are named for what they represent-they steal food and larvae from other colonies to feed their own colony, generally preferring greasy foods. Thief Ants do not have the 2 nodes found on the petiole that are found on the Pharaoh Ant.
American Cockroach, Palmetto Bug, or Water Bug
Periplaneta Americana is a large species of cockroach, winged, and growing to a length of 1 to 1½” (2.5 cm to 4 cm). American Cockroaches can travel quickly, often darting out of sight when someone enters a room, and can fit into small cracks and under doors despite its fairly large size. It is known to be very mobile, it also has wings which allow it to be quite a capable flier. American Cockroaches prefer warmer climates and is not cold tolerant, however, it may be able to survive indoors in colder climates. It does well in moist conditions but also can tolerate dry conditions as long as water is available.
Asian Cockroach Blattella Asahinai is nearly identical to the German cockroach except for a few very minor differences, and the fact that it can fly quite well. Asain Cockroaches are about 5/8″ (1.6 cm) long, tan to brown in color and usually tend to prefer the outdoors more than the German cockroach. Asian Cockroaches can be found in tropical and subtropical climates, such as the southeastern United States.
Brown-banded Cockroach Supella Longipalpa is a small species of cockroach, measuring about 5/8″ (1.6 cm) long. Brown-banded cockroaches are tan to light brown and have two light colored bands across the winds and abdomen, they may sometimes appear to be broken or irregular, but are quite noticeable. Brown-banded cockroaches need less moisture than German cockroaches so they tend to be more broadly distributed in the home, such as in living rooms and bedrooms. They can often be found in homes and apartments, but are less common in restaurants. Brown-banded cockroaches are nocturnal and tend not to be found during the daytime.
Blattella Germanica is a small species of cockroach, measuring about 1/2 to 5/8″ (1.3 cm to 1.6 cm) long. German cockroaches are tan to light brown, and have two dark parallel streaks running from the head to the base of the wings and one of the most common and prominent household cockroaches in the world. In colder climates, it is found only near human habitats, since it is not very tolerant towards the cold. German cockroaches eat a wide variety of items. They particularly like starch, sugary foods, grease and meats. The cockroach can be seen in the day, especially if there is a large population or if they have been disturbed; sightings have been commonly reported often in the daytime hours. However, they are nocturnal, and therefore most active at night.
Smokeybrown Cockroach Periplaneta Fuliginosa is a large species of cockroach, winged, and measures 1 1/4 to 1 3/8″ long, brown in color. Smokeybrown cockroaches prefer warmer climates and are not cold tolerant, however, they may be able to survive indoors in colder climates. Smokeybrown cockroaches can be found in Florida, Louisiana, Mississippi, and other moist gulf coastal states along the southern Mississippi River.
Wood Cockroach Parcoblatta Pennsylvanica is dark chestnut or chocolate brown, with lighter brown wings measuring about 1″ long. Wood Cockroaches are found outdoors in the northeastern, southern, and mid-west regions of the United States quite commonly, but may wander indoors. Although wood cockroaches are not as common indoors as many of the other cockroach species they may be found indoors more often in houses near wooded areas.
Other Crawling Insects
Anthrenus Verbasci are 1/4″ long beetle that can be a serious household pest. The larval form is known as a woolly bear and feeds on natural fibers; damaging carpets, furniture, and clothing. The adult Carpet Beetle primarily feeds on pollen or nectar and can be found on outdoor plants throughout the warm months. Adult females can lay from 30 to 100 eggs throughout their lifetime. Eggs hatch in 1 to 3 weeks are laid in lint, behind and under baseboards, in floor cracks, or other dark protected areas. Larvae develop over 3 to 36 moths and can molt (shed their skin) from 5 to 10 times. The pupa stage lasts 6 to 24 days, but the adult may take up to 3 weeks before it emerges.
Dermaptera are 1/4 to 1/2″ long in length, tan to dark brown in color and mouthparts are adapted for chewing. The Earwig’s abdomen is flexible, muscular, and capable of both maneuvering (opening and closing) their forceps. The forceps seem to be used for a variety of purposes, the main role being self defense. The hind wings are folded in a complicated fashion so that they fit under the forewings, but despite this complex design, earwigs rarely fly. Earwig activity can be located under leaves of plants, cracks, crevices, grass, dark or damp locations.
Gryllus Pennsylvanicus are black or brown and approximately 1″ in length and live in fields or forests where they eat plant material, seeds, fruits. and other living or dead insects. Male Field Crickets sing (by rubbing the front wings together) and dance to attract females, once the female approaches the male will move back and forth in a courtship dance. Female Field Crickets can lay over 400 eggs in their short life span. Adults and nymphs will die off when cold weather arrives however the eggs left behind will over winter and hatch again in spring. Field Crickets are generally nocturnal and more active throughout the darkness of the night.
Firebrats Thermobia Domestica are a small insect typically 1/4 to 1/2″ similiar to the Silverfish. Firebrats prefer higher temperatures, require some humidity, and can be found in bakeries, water heaters (boilers), or near furnaces. They feed on a wide variety of carbohydrates such as book bindings, and can go up to 1 year without eating. Firebrats are distributed throughout most parts of the world and are normally found outdoors under rocks, leaf litter, but are also often found indoors where they are considered pests. They are primarily a nuisance inside the home or buildings, as they don’t cause major damage, though they can contaminate food, damage paper goods, and stain clothing. Female Firebrats may lay from 1 to 195 eggs in a lifetime(approximately 2 to 4 months).
Carabidae with about 40,000 species and considerable variation among them, in length sizes ranging from 3/10 to 2 3/5″ . Common features include a generally dark appearance, possibly iridescent, large head and mandibles. Ground Beetles are found in all habitats, most are nocturnal predators and scavengers, but some, such as the Tiger Beetles are active in the day time, using their eyesight to capture small arthropods. Adult Ground Beetles lifetimes vary from 2 to 4 years, and females will lay their eggs (number of eggs vary depending on nutrition and environmental factors) in the soil.
Scutigera Coleoptrata can live its entire life inside a building and is probably indigenous in the Mediterranean region, but it has spread through much of Europe, Asia, and North America. House Centipedes are yellowish gray and have three dark-colored dorsal stripes running down its length; the legs also have dark stripes. When one of the House Centipede’s legs are held down, it drops that leg in hopes that the attacker will be distracted by the temporary twitching appendage. House Centipedes prefer to live in cool, damp places while most live outside; primarily under large rocks, piles of wood, and especially in compost piles. Within the home, House Centipedes are found in almost any part of the house; most commonly, they are encountered in basements and bathrooms where there is a source water, but they can also be found in dry places like offices, bedrooms, and dining rooms. House Centipedes lay an average of 63 to 151 eggs in the spring and have a life span of 3 to 7 years.
, Sow Bug, Pill Bug, Potato Bug, Rollie-Pollie, Doodle Bug, Armadillo Bug, Wood Louse
Armadillidum Vulgare are soft bodied insects, less than 3/16″ long with long, slender antennae, and chewing mouthparts. They may have four wings or be wingless. They are generally gray or brown in color. is a terrestrial crustacean with a rigid, segmented, calcareous exoskeleton, fourteen jointed limbs and need moisture because they breath through gills and so are usually found in damp, dark places, such as under rocks and logs. Psocids are readily identified (under magnification) by the presence of a large, conspicuous clypeus. Most Psocids live outdoors and have wings, and can be found on tree bark, tree and shrub foliage, or under stones. They are usually nocturnal and are detritivores, feeding mostly on dead plant matter, although they can be a destructive pest in the garden.These psocids are known as ‘barklice’. They sometimes can become quite conspicuous when they congregate in large groups. Barklice feed on fungi, lichen, pollen, decaying plants, and other organic material. They are harmless to plants and no control is necessary. Booklice feed most commonly on molds as well as fungi, grains, insect fragments, and other starchy material, including glue from book bindings. In homes, they can be found in damp, warm, undisturbed places where mold and fungi are growing. They are more likely to be a problem during summer. They are rarely damaging inside buildings but they can become a nuisance because of their presence, especially when they occur in large numbers. The most effective way to control Booklice is to reduce moisture within the structure, most Booklice will not survive once the humidity drops below 50%.
Lepisma Saccharina is a small (10 mm long) wingless, silvery gray in color (the metallic sheen is due to silvery scales, which only appear after the third molt, eats primarily carbohydrates such as sugars and starches. Silverfish may live up to eight years and females lay clutches of hundreds of eggs, usually in a crack or crevice. If conditions are too cold or too dry a silverfish can not reproduce. Silverfish are nocturnal and can often be found under refrigerators or around a well-heated toilet, if the crevices in the floor tiles are large enough.
Springtails or Snow Fleas Collembola form the largest of the three orders of modern Hexapods that are no longer considered to be insects. Springtails are normally less than 6 mm in length, have six or fewer abdominal segments and possess a tubular appendage called the collophore in the first abdominal segment. An abdominal, tail-like appendage called the furcula, is present in most species and is folded beneath the body, to be used for jumping when the animal is threatened. Springtails are frequently found in leaf litter, grass clippings, hay, straw, algae, mold, fungus, and other decaying material. The key to keeping this sporadically occurring pest at bay is keeping the environment dry and clear of organic material.
Palmetto Weevil Rhynchophorus Cruentatus typically can be found throughout the coastline of South Carolina to Texas and are native to Florida but can be relocated when palm trees are removed from these areas and shipped to other locations. Palmetto Weevils are anywhere from 3/4 to 1 1/4″ long, black or black and reddish brown. The larvae are found feasting on palm trees and generally cause enough damage to make the palm tree snap in half. Best treatment includes removing the infested palm trees and destroying any left over wood before the adults lay eggs onto a new or healthy plant.
