No matter where you live, there’s a good chance ladybugs start showing up in large numbers during late summer and early fall. That time of year seems to be especially attractive to them, and once they gather outside, it’s not unusual for them to find their way into your home. Some varieties can even bite, which makes the whole situation even more frustrating.

If you’re tired of finding ladybugs in your hair, on your walls, or crawling across your arm, there’s one scent that may help keep them away: lemon.
According to the source, lemon is a smell ladybugs strongly dislike. Using lemon-scented products around entry points in your home may help discourage them from coming inside. The main areas to target are windows, door frames, and baseboards.

Here are some lemon-based options mentioned:
Lemon Pledge
Lemon Lysol wipes
Lemon Pine-Sol
Coconut lemongrass counter cleaner
A spray bottle filled with water and lemon juice
A spray made with water and Ajax lemon soap
Lemon essential oil diffused indoors
Another method mentioned involves making a simple trap. In one cup of warm water, dissolve two tablespoons of sugar and add two drops of dish detergent. Place the mixture in a dish. It can attract the ladybugs, collect them, and kill them as well.
So, if ladybugs keep making themselves at home in your space, lemon may be the scent worth trying. Using one of these methods around the house could help make your home a lot less inviting to them.
