Why even squash them? You just wave your hand and they float elsewhere.
All the poor girl is trying to do is land on something. She has her boyfriend stuck to her in an uncomfortable manner, which is causing an unscheduled landing. As they float in very slowly at you, perform this elaborate procedure:
Step left or right. One step only.
Picture two houseflies when they couple. Notice they drop out of the air suddenly. With lovebugs, the girl is a big girl and is able to glide the two of them down for a crash landing... but she can't steer much, then she can't shake the dude after that. Instead you see a bug that won't fly much, that looks like two flies butt-to-butt and realize that it is two flies...
Pretty funny really. They have no natural predator because they taste like acid, they etch paint and aluminum because they're acidic, they are drawn to heat and car exhaust, they hatch, play tiddlywinks, lay eggs and die, and do this every 6 months or so.
So really they were just engineered by turtle wax so that you would detail your car in the spring and fall.
