How to Keep Love Bugs Away

If you live in the South, then you already know - love bugs show up like uninvited guests that just won’t leave. One day it’s fine, and the next it feels like they’ve taken over your porch, greenhouse, plastered all over your vehicle, and every outdoor space you actually enjoy using, when the humidity levels aren't so dang high.

Love bugs are more of a nuisance than anything harmful, but when they’re everywhere, it can make sitting outside or working in your yard a whole lot less pleasant. You can't get rid of them completely, but there are ways to help keep love bugs away from the areas you use most.

What Are Love Bugs?

Love bugs are small black flies with a reddish thorax that show up in waves - usually in spring and late summer. You’ll almost always see them in pairs (hence the name), and they tend to hover around warm surfaces, sunlight, and anything that gives off a little heat - like hovering around your body when you're out working in the yard.

They’re not biting insects, and they don’t sting. In fact, a little fun fact, they’re actually part of the ecosystem and help break down organic matter. That’s great… just maybe not right outside your front door.

Love bugs lay their eggs in moist, grassy areas and places with decaying plant material - things like lawns, roadside grass, mulch, and garden beds. When the larvae hatch, they actually help break down that organic matter before eventually turning into the flying nuisance we all recognize.

So if you’ve ever wondered why they seem to suddenly appear everywhere, it’s often because the conditions around your home (warmth, moisture, and vegetation) are just right for them.

Why They Love Outdoor Spaces

If your porch, greenhouse, or shop seems like a love bug magnet, there’s usually a reason:

  • Warm surfaces (metal, glass, siding)
  • Sunlight and heat buildup
  • Moist areas or nearby vegetation
  • Light-colored structures that reflect sunlight

Greenhouses especially can draw them in because they’re basically a warm, bright, slightly humid environment - exactly what love bugs seem to enjoy.

A Simple Spray to Help Keep Love Bugs Away

I remember the first year we moved to our new home and the love bugs showed up… we were like, “what have we moved to?” That year was the worst since we've lived here, it was crazy, they were everywhere! You'd drive on the freeway, come home and the front end of your vehicle would be completely covered in splattered love bugs - and if you don’t wash them off fairly soon, the residue can dry and become hard to remove, sometimes even affecting the paint over time.

I make this simple peppermint essential oil spray and use it around doorways and porch areas, it doesn’t stop them completely, but I do feel it does make the space a little less appealing to them.

DIY Love Bug Spray

  • 1 cup water
  • 1 cup white vinegar
  • 10–20 drops peppermint essential oil

Mix in a spray bottle and lightly spray around:

  • Door frames
  • Window edges
  • Porch railings
  • Around greenhouse entry points

Peppermint has a strong scent that many insects don’t like, and vinegar adds another layer they seem to avoid. This won’t eliminate them entirely, but it can help reduce how many hang around your space.

Other Natural Ways to Discourage Love Bugs

Keep Surfaces Clean

Love bugs are attracted to residue - especially from previous bug splatters.

  • Wipe down surfaces regularly
  • Hose off walls, doors, and windows
  • Clean porch railings and outdoor furniture

It’s not glamorous, but it helps.

Turn Off Lights When You Can

Outdoor lights can attract all kinds of insects, including love bugs.

  • Use softer, warm-toned bulbs
  • Turn lights off when not needed
  • Consider motion lights instead of constant lighting

Add Air Movement

Love bugs aren’t strong fliers.

  • A simple fan on your porch, shop, or in your greenhouse can make a big difference
  • Even a gentle breeze can discourage them from sticking around

Use Screens Where Possible

If you have a porch or greenhouse:

  • Make sure screens are intact
  • Close doors quickly (easier said than done, I know)
  • Patch any small openings

Avoid Standing Moisture

They’re drawn to damp areas.

  • Don’t let water sit in trays or containers
  • Keep greenhouse floors as dry as practical
  • Watch for overwatering around entry areas

Light-Colored Surfaces

They tend to gather on lighter surfaces that reflect heat.

  • If you’re repainting or building, slightly darker or matte finishes may attract fewer bugs
  • Not a must-do, just something to keep in mind

Can You Stop Love Bugs From Showing Up?

No - nothing is going to completely stop love bugs from showing up. They come in waves, and when they’re here, they’re here.

What these remedies can do is:

  • Make your outdoor spaces less inviting
  • Reduce how many gather in one spot
  • Help you enjoy your porch, greenhouse, or shop a little more

And sometimes, that’s enough.

The Love Bug Myth

Every so often, you’ll hear someone say that love bugs were created in a lab in Florida and accidentally released. They were not a lab experiment gone wrong and there is no evidence to support it. Love bugs are actually a naturally occurring species that made their way into the southeastern U.S. over time.

Keeping Love Bugs Away

Love BugsLove bugs may be part of life in the South, but that doesn’t mean you have to share your favorite outdoor spaces with quite so many of them. Simple things like a vinegar and peppermint spray, a little airflow, and keeping surfaces clean can go a long way in making your space feel more comfortable.

You might not win the battle completely - but you can definitely make it a little more manageable.
