Behavioral Ecology- Ants

I am observing and studying ants- I don't know the exact species but I think they might be Argentine Ants. This animal lives around my house and so they are easy to observe and experiment with, and ants are such industrious little critters and have such a structured life I though they would be fun to experiment with. They make their nests in protected areas around my yard: under the porch, and bushes, and fences. It has been interesting to note that by spraying a strongly smelling solution on the trail (but not on any ants), I can wipe out that section of trail and observe them as they make a new one around the smelly patch. A few facts about me are that I invented a sport when I was younger, and I love Harry Potter.
