I have avoided lovebugs completely this year, till I went to shadetrees meetup at dimecitycycles. Holy hell was my car coated after that.
Last fall my house was coated in them, mainly my garage doors. I planted spearment in both flower beds on each side of the garage door and this year, I only see one or two hanging out at the garage, instead of hundreds. The spearmint looked like it was dead all florida-winter, but really took off in march and started to grow like crazy.
Now the love bugs are hanging out around the a/c units, plan to plant some spearment there too and see if I can attempt preventative measures for lovebugs (dethatching the yard), but that might have to wait till more of the land around me sells and actually had a yards instead of decomposing logs.
Do not use fresh paint or light colors as love bugs love that.
