Sentricon

Last updated

The Sentricon Termite Colony Elimination System is a subterranean termite pest control product developed and manufactured by Corteva (Previously Dow AgroSciences). [1] It was introduced in 1995 as a termite baiting system and an alternative to liquid termicide soil barriers. It eliminates all members of the termite colony, including those of the Formosan subterranean termite colonies. [2]

Operation

The baiting technique employed by the Sentricon System takes advantage of termite biology and behavior. Subterranean worker termites forage for cellulose food sources 24 hours a day, ranging abroad from their underground nest, or colony, through tunnels in the soil that can extend up to 300 feet or more. When worker termites find a food source, they leave a pheromone scent trail to summon nest mates. [3] Worker termites chew and digest cellulose, and then regurgitate it to share with other termites in the colony. [4] [5]

Sentricon bait stations are installed in the soil, creating a protective perimeter around a property. These stations are baited with a cellulose material impregnated with noviflumuron , a chitin synthesis inhibitor. When foraging, worker termites find the stations, eat the bait material, and then regurgitate it for colony nest mates to consume. Termites affected by noviflumuron later die as the compound inhibits molting and is its effects are inconspicuous to termites as to where it originates. As termites within the colony die, the colony is eliminated, typically over a period of months. Noviflumuron bait treatment requires less disruption of buildings and surroundings than traditional methods based on creating a barrier of termicide-treated soil around the structure to be protected, but noviflumuron bait treatment also needs to be continued indefinitely to prevent re-infestation in areas where termites are endemic. [6]

In 2000, the Sentricon System received the Presidential Green Chemistry Challenge Award, an environmental honor from the U.S. government. [7]

Effectiveness

Sentricon has been extensively tested. [8] Multiple independent research studies have shown that its bait matrix and baiting technique is an effective termite control option. [1] [9] [10] Field evaluations have documented the elimination of subterranean termite activity, including that of Formosan subterranean termites, often within 3 to 6 months. [2] Ongoing monitoring and re-baiting is critical to termite colony elimination. Without proper oversight, re-infestation from neighboring foraging colonies can occur. However, such re-infestations have not included any members of the original colony. Long-term studies have shown that by implementing the recommended service frequency, approximately 60% of the colonies are eliminated during the first quarter, approximately 75% of the colonies are eliminated after the second quarter, and nearly all colonies are eliminated within a year of the initial baiting, with all colonies ultimately being eliminated. [11] [12] According to the Dow AgroSciences, Sentricon is used by organisations that include Independence Hall, the Statue of Liberty, and the White House [13] [ unreliable source? ]

<span class="mw-page-title-main">Termite</span> Social insects related to cockroaches

Termites are a group of detritophagous eusocial insects which consume a wide variety of decaying plant material, generally in the form of wood, leaf litter, and soil humus. They are distinguished by their moniliform antennae and the soft-bodied and often unpigmented worker caste for which they have been commonly termed "white ants"; however, they are not ants, to which they are distantly related. About 2,972 extant species are currently described, 2,105 of which are members of the family Termitidae.

Blattodea is an order of insects that contains cockroaches and termites. Formerly, termites were considered a separate order, Isoptera, but genetic and molecular evidence suggests they evolved from within the cockroach lineage, cladistically making them cockroaches as well. The Blattodea and the mantis are now all considered part of the superorder Dictyoptera. Blattodea includes approximately 4,400 species of cockroach in almost 500 genera, and about 3,000 species of termite in around 300 genera.

<i>Reticulitermes flavipes</i> Species of insect found in North America

Reticulitermes flavipes, the eastern subterranean termite, is the most common termite found in North America. These termites are the most economically important wood destroying insects in the United States and are classified as pests. They feed on cellulose material such as the structural wood in buildings, wooden fixtures, paper, books, and cotton. A mature colony can range from 20,000 workers to as high as 5 million workers and the primary queen of the colony lays 5,000 to 10,000 eggs per year to add to this total.

<i>Mastotermes darwiniensis</i> Species of termite

Mastotermes darwiniensis, common names giant northern termite and Darwin termite, is a termite species found only in northern Australia. It is the most primitive extant termite species. Contrary to common belief, this species does not form mounds as the nests are subterranean and inconspicuous. Colonies will readily occupy and infest decomposing wood but primarily live in a complex subterranean network of tunnels and galleries which they use to travel to new food sites. Colonies may eventually split and form isolated satellite colonies.

<i>Coptotermes gestroi</i> Species of termite

Coptotermes gestroi, commonly known as the Asian subterranean termite is a small species of termite that lives underground. Both this species and the Formosan subterranean termite are destructive pests native to Asia, but have spread to other parts of the world including the United States. In Asia, this species is known as the Philippine milk termite.

The Hodotermitidae are a basal Old World family of termites known as the harvester termites. They are distinguished by the serrated inner edge of their mandibles, and their functional compound eyes which are present in all castes. They forage for grass at night and during daylight hours, and the pigmented workers are often observed outside the nest. Their range includes the deserts and savannas of Africa, the Middle East, and Southwest Asia. Their English name refers to their habit of collecting grass, which is not unique to the family however.

Incisitermes minor is a species of termite in the family Kalotermitidae known commonly as the western drywood termite. It is native to western North America, including the western United States and northern Mexico. It has been found in many other parts of the United States, all the way to the East Coast.

Coptotermes is a genus of termites in the family Rhinotermitidae. Many of the roughly 71 species are economically destructive pests. The genus is thought to have originated in Southeast Asia.

<i>Coptotermes acinaciformis</i> Species of termite

Coptotermes acinaciformis is a species of subterranean termite in the family Rhinotermitidae native to Australia. Termites are social insects and build a communal nest. In the case of C. acinaciformis, this is either in the root crown of a tree or underground. From this, a network of galleries extends through the nearby soil, enabling the workers to forage in the surrounding area without emerging on the surface of the ground. This termite can cause substantial damage to trees and the wooden parts of buildings.

Heterotermes indicola, is a species of subterranean termite of the genus Heterotermes. It is native to tropical India, Pakistan and Sri Lanka but has extended its range into the subtropics and warm temperate areas of the Himalayan foothills to altitudes of about 2,000 m (6,600 ft). It causes damage to timber in buildings and is one of the most destructive termites in urban and agricultural areas in the world. Soldiers are about 4.1-4.9mm long. Extracts of garlic and Calotropis procera are known to have termiticidal effects on H. indicola.
