Spectracide Terminate Termite Detection & Killing Stakes is two products in one ? the pop-up indicators detect termite activity, and the stakes kill foraging termites. Place the stakes 2 to 3 feet away from your home and no more than 10 feet apart. Use stakes in termite-favorable areas, including under around decks or crawl spaces ? place more stakes in moist areas. Read and follow all directions before using this product. Termites rarely come to the surfaces of what they're eating, so most of the time you will never know they have invaded your home until it is too late. Using Spectracide Terminate Termite Detection & Killing Stakes is an important step toward reducing your risk of termite damage. It is very important that you monitor your stakes as directed and replace all stakes after 12 months of use. Not recommended as sole protection against termites, and for active infestations, get a professional inspection.
