Ants, we throw bug sprays and bombs at them, only to mask and put off the problem. Many times we reach for harmful pesticides or sticky traps and but end up calling an exterminator to handle it. With more than 12,500 species of ants classified, you need to know whom you are up against. Believe it or not, there are great ways to put out the "unwelcome" mat and get those guys to to stay out.
