In some rare instances, the ant's sting can cause severe allergic reaction or even death to those who already have been stung, experts say. In the Southern states where the ant has long made its home, the insect has become a notable health hazard according to the American College of Asthma and Immunology in Chicago. At least 40 people die in the US each year from insect stings. As with other insect stings, the most severe cases occur in people with an allergy to the insect's venom that have previously been stung and sensitized to it. In such repeat exposures, those allergic to ant venom may experience swelling of the larynx and tongue and, in the worst cases, dizziness, a drop in blood pressure and unconsciousness.
Allergists recommend immuno-therapy for people who have confirmed sensitivity to ant venom.
This involves a series of injections to build up a tolerance to the venom's allergens. A Tim-Bor solution is pressure injected into infested wood. The foam consists of air bubbles which slowly collapse allowing the chemical a delayed, more thorough saturation of the wood. Tri-Valley has begun using this type of termite treatment as part of its ongoing efforts to keep abreast of the latest technological advances in pest control.
