How do you repel lovebugs?

Lovebugs dislike citrus smells, so lighting citrus-scented mosquito repellent candles, or using a citrus soap solution mixed with some mouth wash as a spray can keep the insects away for a while. If the bugs have entered the house, use a vacuum cleaner to catch them and discard them in a bag.

Does peppermint oil keep love bugs away?

A few essential oils not only smell great, they can keep lovebugs (and sweat bees) away. The exact ratio is up to you, but generally a good lotion will include 3% each of peppermint and citronella, as well as 4% turmeric. The other 90% can be lotion, water, baby oil, or whatever else you prefer.
