Ants cause various types of damage, depending upon the variety. Carpenter ants tunnel through wood, destroying structures. Pharaoh ants may transmit serious diseases. A fire ant’s sting is potentially deadly to susceptible individuals, and all ants contaminate the food they infest.
Pest Control Services For Ants
Ants build massive colonies, so their presence is generally detected when you see their nests, or the ants themselves. Treatments involve baiting, insecticide, and sealing off entry to buildings.
Odorous House Ants Tapinoma sessile (Say)
Color: Brown or black
Shape: Segmented; oval
This ant gets its name from the strong, rotten coconut-like smell it gives off when crushed. These tiny insects range in size from one-sixteenth of an inch to one-eighth of an inch long.
Odorous house ants like to eat sweets, especially melon.
Typically living for several “months,” these ants make their home in a variety of areas both indoors and outdoors.
These ants do not pose a public health risk, but they can contaminate food and should be avoided.
Eliminate standing water. Pests such as odorous house ants are attracted to moisture. Keep tree branches and other plants cut back from the house. Sometimes pests use these branches to get into your home. Make sure that there are no cracks or little openings around the bottom of the house. Sometimes pests use these to get into your home. Make sure that firewood and building materials are not stored next to the home. Pests like to build nests in stacks of wood.
Workers monomorphic, about 1/16-1/8″ long; queens about 1/4″ long. Body light brown to black. Antenna 12-segmented, without a club. Thorax lacks spines, profile unevenly round. Stinger absent. Workers emit a disagreeable, rotten, coconut-like odor.
Colonies may be composed of several hundred to 100,000 ants, but usually number about 2,000 to 10,000 ants. There are usually many queens in a colony. Developmental time (egg to adult) is 34 to 83 days, varying with temperature during summer months, and up to 6 to 7 months during the winter. Colonies typically produce 4 to 5 generations a year. Although, they mate both inside and outside the nest, the first swarmers appear from May to mid-July. Colonies can be founded by inseminated females or by budding. The workers and queens live for several years. Individuals from different colonies are not hostile to one another and workers normally move along trails.
Inside, these ants usually construct their nests near a moisture source such as in wall voids especially around hot water pipes and heaters, in bathtraps, beneath commodes with leaking seals, in crevices around sinks, cupboards, etc., but also in wood damaged by termites. 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 including stacks of lumber, firewood, bricks, etc. They have been found nesting in honeybee hives beneath the top and inner cover. Workers feed on live and dead insects, seek honeydew and plant secretions, and even feed on seeds. They are extremely fond of honeydew and attend such honeydew-excreting insects as plant lice (aphids), scale insects, mealy bugs, 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. They forage during the day and at night when the temperature is 43-95 degrees Fahrenheit. Like most ants, they follow guidelines or edges. They tend to move their nests every 3 months or so, often in response to rain. When workers are alarmed, they run around in an erratic manner with their gasters/abdomens raised up.
Control is a 4-step process. First, location of the nest(s) is crucial and can often be accomplished by following the trail of foraging workers back from the food source. Treat the nest(s) directly with an appropriately labeled pesticide. Second, a thorough perimeter treatment of a nonrepellent pesticide is highly effective in eliminating the ant problem; be sure to treat up under the bottom siding-to-foundation wall junction if present. In addition, all branches of trees and shrubs in contact with the building must be trimmed back. Be sure to check where electrical and water lines enter the building and caulk any gaps. Third, on the inside, lightly mist/spritz and foraging trails of ants with a nonrepellent pesticide. This will speed up the control process. This outside-inside combo treatment will usually give results in a few days at most. Be sure to cover any surfaces below the application site with plastic before application to avoid unwanted contamination. Fourth, baiting on the outside just beyond the treated area with a sucrose-based liquid bait will intercept the ants before they enter and give greater control for a longer period of time. This works best if inside sources of moisture and food are eliminated first.
