Answer 1

You can buy the ant repellant and killer at at Lowes or Home Depot to put around your house.

I looked in my garage and I couldn't find it but I bought this white powder that you mix with water and spray it in a pump sprayer around the front door for the fly problem.It works.

I found it in a feed store.Sorry I couldn't remember the name.

Answer 2

Believe it or not baking soda works. make a barrier with it.  The way it works is it has sharp particles and when the ant touches it it cut it and enters its body, and end results is it dehydrates the ant. The other one that works is borax(20 mule team is still av able. Both are safer than insecticide. As far as the flys, your on your own.

Answer 3

ants will not cross a chalk line  sounds funny but its true
