Try using some dish soap or detergent and make a very soapy sudsy solution and place it where ever you have love bug problems. They will get stuck in the solution and its an easy way to rid your self of some of the swarm of love bugs that bother you.
Purchase an inexpensive spray bottle attachment for your hose ($4 Wal-Mart). Fill it with Joy detergent (or your favorite kind) and spray down all the areas you see the love bugs. The soap suds create a balloon effect around the love bug and suffocate them. After the soapy attack spray again with just water to remove the dish detergent.
A good non toxic way to get rid of them is with dish detergent. Buy a bottle attachment for your water hose and fill with your preferred brand. Sparay down the yard and you will have dead love bugs.
