When applied around the foundation of your house, borax will keep ants and spiders from entering your home. Sprinkle it on the weeds and vegetation in the driveway, walkway and sidewalk cracks. Caution: Borax is toxic to plants, so only sprinkle it on the vegetation you want to kill. Typical symptoms of toxicity from exposure to excess Boron or other ions are yellowing of leaf margins and tips and sometimes between veins. Symptoms progress to necrosis (browning) and premature drop of foliage. Research shows low levels of Boron can contribute to a sluggish brain, poor cognitive development, and trouble learning or retaining information. Boron is often considered a "brain nutrient" because it can help with task performance, better motor control, attention and even short-term memory. In addition, it has proven to be an effective mineral for treating and preventing osteoporosis because of its ability to activate important vitamins and minerals in the body. Additional research must be conducted to determine a recommended daily amount of Boron. Instead of sprinkling borax in the bottom of your trash can, try baking soda or used (or fresh) coffee grinds, which all work wonders. You can also use baking soda and water to clean your trash can. Throw in some vinegar for extra odour-fighting action.
