Termite & Pests

Beware of Termites

More than 365,000 homes in the U.S. are involved in a fire each year. More than 600,000 U.S. homes suffer termite damage totaling more than $1.5 billion annually. This is more than the damage caused by all fires, storms, and earthquakes combined. More than 2 million homes require termite treatment each year. Homeowners insurance can help recover losses from fires, floods, and earthquakes, but it is almost impossible to get insurance against termites.

Finding out your home has termites scares most homeowners. You typically can't see them, you can't hear them and frequently only a trained inspector can find signs of infestation.

Treatment by the homeowner for the control of termites is virtually impossible. Specialized equipment is used and the experts have the knowledge necessary for effective control.

A trained termite control specialist can provide protection from termite infestation. Termites are found in almost every state as well as Mexico and parts of Canada. They eat wood and may also destroy paper products such as books, cardboard boxes, furniture and various other items. Even buildings with steel framing and masonry walls are targets because of the wooden doors and window frames, wooden support beams, cabinets, or shelving.

How Termites Live

There are more than 2,000 species of termites. Only about 70 species invade wooden structures enough to be considered pests. The most damaging are roughly 20 species we call "subterranean" termites because of their living and foraging habits. Two of these, the Eastern Subterranean Termites and the Western Subterranean Termites, are by far the most common, widest distributed and most damaging in the US. The following description of biology refers to these two closely-related species.

Termites feed on cellulose, a complex chemical in plant cell walls, and they are very important in natural decomposition of fallen trees, leaves and other plant products. Subterranean termites build their colonies in the soil or trees or poles, and they rely mainly on the soil for moisture.

A subterranean termite colony is large (60,000 to 1.5 million termites), and made up of several "castes," each with distinct functions and behaviors. These include reproductives (the queen, king, and winged swarmers), soldiers, and workers. Worker termites are small (0.1-0.25 inch long), creamy-white insects. Soldiers are larger (0.2-0.4 inch long), about 1/20th as numerous as workers, and have a large, dark head, with long, strong, sharp-pointed jaws, which they use to attack intruders. Property owners seldom see the worker or soldier termites, but in the spring or fall they may see swarming "winged reproductives." This form of termite can be easily confused with a winged ant unless you look closely.

Two Other Types of Pest Termites

Formosan Termites

Formosan termites are an exotic species that was accidentally introduced to the U.S. from China and other Asian countries. Their habitats are very much like those of our common subterranean species discussed above. They are in the same family of termites, but they belong to a different genus. They are a little bigger and are much more aggressive invaders, forming larger colonies (often 2 million or more). Formosan termites can establish secondary colonies in very moist wood of upper stories of buildings (several stories above ground) and do not need soil contact if there is a nearly constant moisture source. They have been reported from 11 states including: Alabama, California, Florida, Georgia, Hawaii, Louisiana, Mississippi, North Carolina, South Carolina, Tennessee, and Texas. Their distribution will probably continue to be restricted to southern areas because their eggs will not hatch below about 20E C (68E F). If you think you might have an infestation of this species, contact a knowledgeable expert from your local pest control firm, or the entomology department of a university, or NPMA to confirm their ID.

Drywood Termites

Drywood termites live in wood that has fairly low moisture content and is not in contact with soil or any other moisture source. They must get their needed moisture from the wood they live in, so they are usually found in humid coastal or subtropical areas. They can be transported to other areas in infested furniture, picture frames, decorative wooden objects, or wood for construction. Colonies of these termites are relatively small (fewer than 3,000 individuals), and they increase slowly, requiring several years before any swarmers reproduce. They do not build mud "shelter tubes" which are typical of most species of subterranean termites.

Their damage is usually localized, but quite a bit of damage can result from multiple colonies in one building or structure. Drywood termites can be successfully eliminated by a variety of methods that would not be effective against subterranean species. Heating, freezing, focusing microwaves, or high-voltage electric charges on or into all or a portion of the infested structure, or wooden object(s), can kill off whole colonies. Batch fumigation of infested wooden items can also be effective against these termites.

Fire Ants

Fire Ants colonies are established as far north as Conway. Isolated instances may be found farther north due to importation in landscaping materials.

These ants get their common name from their very painful bites and stings. They are small (workers are 1/16 - 1/4 inch long) yellowish-red to black ants, all in the Genus: Solenopsis, which are distributed from Virginia to Florida, and from Georgia to California. Workers of most species are several different sizes. They usually nest in the ground, but sometimes part (or a whole colony) may be located within a structure, usually in wall voids near heat or moisture (such as near a chimney or a bath trap). The two most important species are the Red Imported Fire Ant (RIFA), Solenopsis invicta Buren, and the Southern Fire Ant (SFA), Solenopsis xyloni McCrook.

Colonies of the RIFA may be as numerous as 30 to 100 per acre, with 80,000 to 250,000 ants per colony. They sometimes form multi-queen colonies that may be still larger. Mature queens may lay up to 1,500 eggs per day. Swarming may occur 6-8 times per year. A typical RIFA colony mound is rounded, about 18 inches high, and about 24 inches across. Mounds have caused farm machinery to break, and farm animals have reportedly been killed by multiple stings (thousands) when they stepped into a RIFA mound. People usually develop a blister-like pustule at the site of a sting and true allergic reactions to fire ant stings can be life threatening.

Researchers are field testing some specialized parasitic flies and pathogens against the RIFA, but the most effective and efficient control strategy is to do a wide-area (community wide) baiting followed by drenching individual mounds, those which are still active 10-14 days after the baiting effort, using properly labeled residual insecticides. Call us for help in controlling your RIFA problems.

Odorous House Ants

Odorous House Ants Odorous House Ants

COMMON NAME: Odorous house ant
SCIENTIFIC NAME: Tapinoma sessile (Say)
CLASS/ORDER/FAMILY: Insecta/Hymenoptera/Formicidae
METAMORPHOSIS: Complete


INTRODUCTION. The pungent, "rotten-coconutlike" odor given off when this ant is crushed gives it its name. It is a native species and is found throughout the United States.

RECOGNITION. Workers monomorphic, about 1/16-1/8" (2.4-3.25 mm) long. Body brown to black. Antenna 12-segmented, without a club. Thorax lacks spines, profile unevenly rounded. Pedicel 1-segmented, with small node/segment hidden/concealed from view from above by base of gaster. Gaster with anal opening slitlike, lacking circlet of hairs. Stinger absent. Workers emit a disagreeable, rotten, coconut-like odor.

BIOLOGY. Colonies may be composed of several hundred to 100,000 ants. There are usually many queens in a colony. Developmental time (egg to adult) is 34-83 days, varying with temperature during summer months, and up to 6-7 months during the winter. Colonies typically produce 4-5 generations a year. Although they probably mate both inside and outside the nest, the first swarmers appear from May to mid-July. The workers and queens live for several years. Individuals from different colonies are not hostile to one another and workers normally move along trails.

HABITS. Inside, these ants usually construct their nests in wall voids especially around hot water pipes and heaters, in crevices around sinks, cupboards, etc. These ants prefer sweets but also eat foods with high protein content and grease such as meats and cheese.

Outside, they are often found in the nest of larger ants, in exposed soil, but mostly under objects. Workers feed on insects, seek honeydew and plant secretions, and even feed on seeds. They are extremely fond of honeydew and attend such honeydew-excreting insects as plantlice (aphids), scale insects, mealybugs, etc. They are most likely to enter buildings when their honeydew supply is reduced such as during rainy weather or with leaf fall in the autumn.

When workers are alarmed, they run around in an erratic manner with their gasters/abdomens raised up.

CONTROL. Location of the nest(s) is crucial and can often be accomplished by following the trail of foraging workers back from the food source. Use of boric acid dust in the voids of outside ground-floor walls and infested interior walls along with barrier treatment is effective. Baiting is often required.
