As simple as it may sound, capturing ladybugs with a dustpan or vacuum is one of the simplest ways to remove a colony.

For example, vacuum a large group of ladybugs and immediately empty the vacuum bag outside.

If the infestation has not grown too severe, physically relocating the colony will dissuade more people from joining. Wash the area with soap after removing any chemical trails that might have been left behind to attract new bugs.

Spray Vinegar

Fill an empty spray bottle with white vinegar and thoroughly spray all over the place where you notice ladybugs resting or crawling.

Light Trap

One way to help keep ladybugs out of your home is to create a light trap; the beetles will flock toward the light but get stuck in the trap, ready for release outside.

This can be done by placing a light bulb in an inverted jar and leaving the area around the jar clear.

The ladybugs will fly towards the light and get trapped inside. You can then release them elsewhere or dispose of them.

Diatomaceous Earth

Diatomaceous earth is a natural, non-toxic way of getting rid of ladybugs.

It works by puncturing the exoskeleton of the ladybug, which leads to dehydration and death.

Simply put on a mask, get your goggles out, and sprinkle the white powder around the windows and doors of your house.

They should be used as a last resort, in tandem with other control methods.

There are a variety of chemical repellents on the market, and it is important to read the label and follow the instructions carefully.

These include using essential oils like peppermint, eucalyptus, and lemon; spraying vinegar around doors and windows; using plants like lavender, basil, and mint near entrances; and placing bay leaves in strategic places.
