Liquid Treatments can be used either outside or inside the home. For over 50 years, liquid treatments consisted of the application of a repellent liquid. Repellent liquids are designed to force the termites away from the area treated. While these applications certainly had their day, holes in the "contiguous" barrier allowed termites, in their persistence to enter structures and continue their damaging feeding. While repellent liquids are still available, they are simply not the best choice today.
Undetectable, Non-Repellent Liquids provide the best choice for liquid treatments today. Unlike the repellents, these products actually allow the termites to forage wherever they desire, including into the contiguous termite barrier. That's where the "undetectable" feature triumphs. Foraging termites cannot detect the treatment barrier, and since they've not been repelled, they travel throughout the treatment barrier, without even suspecting that their days are numbered.
Two primary undetectable products lead the industry in liquid treatments.
Fipronil kills insects when they eat it or come in contact with it. Fipronil works by disrupting the normal function of the central nervous system in insects. Fipronil is more toxic to insects than people and pets because it is more likely to bind to insect nerve endings. Brand names currently include Termidor, well known for its broad television advertising campaigns.
Imidacloprid was first released for use in the public arena in the USA more than 7 years ago – it is the original non-repellant termiticide. It provides immediate protection from termites like no other product. Termites are eliminated as they ingest or contact it in a treated soil area around the perimeter of a building or other timber structure. Brand names include Premise, by Bayer, and Prothor SC by Ensystex. termite treatment
Both fipronil and imidacloprid have been extensively tested by many state and federal agencies. Imidacloprid products have been on the market longer, are less expensive than fipronil products, and are rated as better value for the money.
