The last couple of years I have been using a product called a "love bug sponge" which I ordered off the Internet. Then with using Spray 9 cleaner and scrubbing with the love bug sponge, it works as well as anything I have found, so far. We made a trip up to WDW, the Fort Campground, a couple of weeks back and just north of Yeehaw junction on the turnpike, the love bugs were thick during the mid day time.
Was talking to another Florida resident at the Fort and he told me he had switched to using witch Hazel cleaner to spray on the dead bugs. He said it seemed to dissolve the glue of the bugs and after a four or five minute soak, they would come off easily with a sponge and regular car soap in water.
No matter what I use, it seems to take about three hours to get the RV and the truck clean of the love bugs but you sure don't want to leave them on the rig or they will damage the paint.
This was from May of 2013. It took about an hour to collect all these love bugs, as we headed home from Disney.
