The Argentine Ant is 1/16” long with light brown to brown coloration. This ant usually nests near moisture sources such as water pipes and potted plants. They prefer sweets such as honeydew, soda, and fruit juices. Colonies typically consist of 10% queens and 90% workers with a population buildup in spring. A super colony consisting of billions of individual ants was found occupying an area of roughly 3,600 miles in southeastern Europe.
Big Headed Ant
The Big Headed Ant is 1/16’-1/4” long with light brown to crimson brown coloration. The Big Headed typically nests under rocks, patio blocks, & firewood. They also make small mounds in open compacted ground such as construction sites and parks. They consume insects and seeds, but will eat honeydew if it is readily available. Colonies are multi-queened and typically number 200-300 individuals, colonies have been found numbering 3,000 however.
The Carpenter Ant is 1/8”-1/2” long with black coloration. This ant nests in wood (preferably weakened with moisture damage) but will readily infest sound wood as the colony grows. They have also been known to nest in insulation and wall voids. The Carpenter Ant eats insects and honeydew. They will also feed on eggs, meat, grease, and protein rich substances. They do not eat wood, they are not termites, they burrow through wood to house the colony. Colonies typically reach a population 3,000 workers with as many as 15,000 with satellite colonies.
The Pavement Ant is 1/16”-1/8” long with light brown to black coloration. The name comes from its predisposition to nest near or under pavement. The Pavement Ant consumes live or dead insects, honeydew, and household foods left unattended. The Pavement Ant will even create a symbiotic relationship with aphids. The ants will protect the aphids from predators will eating the honeydew the aphids secrete. Colonies range from 5-4,000 individuals consisting on many queens.
The American Cockroach is 1 3/8”-2 1/8” long. The nymphs (juvenile stages) are a rusty red while the adults are a light to medium brown with a yellowish band around their pronotal shield (where the shoulder blades would go). Their egg sacks, called oothecas, look like a dark reddish purse and are 3/8” long. Each ootheca contains 16 eggs.
The German Cockroach is ½-5/8” long. The adults are light brown with two dark longitudinal strips down their pronotal shield (where the shoulder blades would be). The nymphs (juvenile stages) are light brown with two dark longitudinal strips down their body. Their egg sacks, called oothecas, look like small light brown purses which measure ¼-3/8”. Each ootheca contains 30-40 eggs.
The Oriental Cockroach is about 1” long and shiny black in color. Adults males have undeveloped wings and cannot fly. The adult females and nymphs (juvenile stages) are shiny reddish brown to black and do not have wings. Their egg sacks, called oothecas, are reddish brown and look like a purse. They are 3/8” long. Each ootheca contains 16 eggs.
The Turkestan Cockroach is about ½-7/8” long. Adult males are a golden yellow while adult females are dark brown to black in color. Nymphs (juvenile stages) are a rust reddish color with dark brown to black rears. This is one of the most common cockroachs found in southern Utah. Their egg sack, called oothecas, are dark brown and are about 3/8-1/2” long. Each ootheca contains 18 eggs.
Spiders & Scorpions
The Black Widow Spider is about ½” long with an almost spherical abdomen. The female is shiny black with a red hourglass shape on her underside abdomen. The male is a light brown color with a variety of color patters on their abdomen. Only the female Black Widow has a toxic bite that is of concern. The female’s venom is a neurotoxin. A neurotoxin attacks neurological pathways and can cause chills, vomiting, cramps, delirium, and/or partial paralysis.
The Hobo Spider is about 7/16-9/16” long with light brown coloration. They have a dark strip down either side of a lighter midline. A bite from this spider will typically leave a necrotic wound or lesion. A necrotoxin kills off heath cells while preventing the body from engulfing and removing the dead cells, this cause a buildup of dead tissue on the bitten victim.
A Drywood Termite is roughly 5/16-1/2” long with amber to dark coloration. Swarming termites will have equal ended wings which will be cast once the termite has found a suitable home. The local drywood termite needs 12% or less moisture content. A colony is broken up into workers (those who damage your home), soliers (does who protect those who damage your home), and queens (those who give birth to those who destroy and protect). This particular termite does not need to come in contact with soil and will not build mud tubes.
A Subterranean Termite is roughly 3/8” long with yellowish amber to pale white coloration. Swarming termites will have equal ended wings which will be cast once the termite has found a suitable home. The local subterranean termite is less dependent on moisture and decay as related subterranean, they will readily consume dry, sound wood. However, moisture is a leading cause for subterranean termite presence. The colony consists of workers, queens, and soldiers. This particular termite residence in the soil and may build mud tubes to access your property.
The common bed bug is 3/16” long and yellowish to dark reddish black in color. The wide variety in color is due to their partially translucent exoskeleton. The lighter in color they are, the longer it has been since their last feeding. On close inspection, the bed bug is covered with tiny golden hairs which alert it to alterations in its environment. Presently, scientists tell us that bed bugs DO NOT transmit blood pathogens.
