In Delta, 50% of every home has ants indoors and 100% outdoors. When you have these irritating ants in your home, there is one quick fix to temporarily get rid of these mighty six legged homewreckers. You don’t have far to go to get it either, it’s with all your baking goods – baking soda. Merely sprinkle a very fine dusting of soda any where to are seeing them coming and going. The ants will get the baking soda on their fine hairs of their legs and because they are continuously cleaning themselves, they will ingest the soda. The soda reacts with the ant’s digestive chemicals and produces carbon dioxide bubbles, which explode the infected ant from the inside out. If they regurgitate the soda in the process of feeding other ants, larvae or the queen- this could (in theory) kill off the entire nest.
