  • Imported fire ants, Solenopsis invicta and Solenopsis richteri are a substantial pest.
  • Imported fire ants have plagued the United States farmers, homeowners, park directors, livestock, pets and wildlife ever since its introduction at Mobile, Alabama in 1918.
  • ornamental nurseries ship plants from the infested states to other uninfested areas of the country, they are required by law to take special precautions to prevent imported fire ants from moving with plants or soil .
  • These precautions are mandated by the Federal imported fire ant quarantine regulating such nursery stock shipments and to comply with these regulations, soil is treated with insecticide. Fire ants sting humans and livestock, feed on germinating seeds and crop seedlings thereby reducing yields and
  • Pharaoh ants have the ability to carry at least twenty known pathogens on their bodies and therefore can be a major threat to the health of patients.
  • Other Monomorium species are pests because of their mere presence in structures . Camponotus species or carpenter ants, form their nests in wood and other moist areas and although they do not consume the wood as termites do, they can cause structural damage.
  • Ghost ants Tapinoma melanocephalum, nest in potted plants, soil, gravel, aluminum doors and in organic material that collects at the base of palm fronds. Because the ants can be shipped with potted plants, they are also considered nuisance pests. Crazy ants, Paratrechina longicornis, named so because of their rapid and erratic movements, are nuisances as they collect crumbs and debris around gas stations, cafes and convenience stores. While not related to the imported fire ant, the little fire ant, Wa ⁇ mannia
  • Pheidole megacephala the big-headed ant
  • Pheidole megacephala is a pest in agricultural crops (pineapple) where it tends honeydew producing insects and protects them from natural enemies.
  • the big-headed ants are also a pest in urban environments where large infestations often leave obvious piles of dead workers throughout the structure.
  • Crematogaster species a species that typically nests outdoors in hollow plant cavities, can also invade homes using branches and wires as a guideline. They have been known to short-circuit telephone wires and damage rafters, posts, shingles, insulation and fiberboard.
  • Ants can be excluded from areas by using chemical compounds called repellents which cause ants to either leave areas in which they are in highest concentrations or not pass across areas on which the repellents have been deposited (Shorey et al, Physiological and Chemical Ecology, Volume 22 (5) , 920-924, 1993) . Shorey et al tested a number of compounds that had been reported as alarm pheromones of ants or ant-defensive allomones elaborated by a variety of plants and animals .
  • United States Patent No. 5,648,390 disclose a number of compounds that have repellent activity for the imported fire ant, Solenopsis invicta . These compounds include carboxylic acids such as octanoic acid, alcohols such as octanol , ketones such as 3-octene-2-one, and carboxylic acid esters such as l-nonen-3-yl acetate.
  • repellent compositions While various repellent compositions are known in the art, there remains a need in the art for highly effective repellents to improve the control of social pest insects, especially ants.
  • the present invention provides a repellent composition and method of use which is different from related art repellents.
  • Another object of the present invention is to provide a repellent composition for the control of ants.

  • a still further object of the present invention is to provide a method for repelling social insects using a composition containing a repelling amount of neral .
  • Social insects such as ants, wasps and termites have well developed foraging mechanisms.
  • Social insect pests are treated in accordance with the invention by dispensing a repellent composition containing alkadienals in any suitable way in an area where it is necessary to prevent the presence of social pest insects .
  • the red imported fire ant, Solenopsis invicta; the Argentine Ant, , Linepi thema humile (formerly Iridomyrmex humilis) and the Pharaoh ant, Monomorium pharaonis, are used as a model system.
  • the term repellent for the purposes of this disclosure includes alkadienals in amounts effective to repel social pest insects from any desired area where social insects are a problem.
  • alkadienals are the octadienals .
  • the preferred octadienals are 3 , 7-Dimethyl-2 , 6-octadienal which includes the racemic mixture citral, the cis isomer-geranial and the trans isomer-neral .
  • Citral is a constituent of oil of lemon grass and is also present to a limited extent in oils of verbena, lemon and orange. Citral is approximately 66.6% geraniol and approximately 33.4% neral.
