What is that product on TV that keeps bugs out of your house?

Question:Lately there's been a commercial playing for this product you spray around the in and outside of your house to kill existing bugs and prevent more from coming inside your house. Does anyone remember what this is called?

And if so, has anyone tried it or do you know anything about it?

Thanks~

What I have seen was Home Defense, it works. You can buy it at Lowe's or Home Depot.
