How To Get Rid Of Ladybugs
Ladybugs can become a nuisance when they invade homes in large numbers, especially in the fall as they seek warmth for overwintering. Here’s how you can get rid of them and prevent future infestations:
Ladybug Removal
Vacuuming: The easiest and most effective method is to vacuum them up. Use a shop vac or vacuum with a HEPA filter to prevent allergens from spreading. Empty the vacuum bag or canister outside immediately.
Trap Them: Place a light trap in dark areas where ladybugs congregate. They are attracted to light and will fly into the trap.
Dish Soap Spray: Mix a mild solution of water and dish soap in a spray bottle and apply it directly to the ladybugs. This kills them on contact.
Prevent Ladybug Infestations
Seal Entry Points: Inspect and seal cracks around windows, doors, siding, vents, and utility openings using silicone caulk or weather stripping. Ladybugs enter through even the smallest gaps.
Use Screens: Make sure all vents, chimneys, and attic openings are properly screened.
Apply Diatomaceous Earth: Sprinkle food-grade diatomaceous earth around windows and doors. This natural powder dehydrates and kills insects.
Use Essential Oils: Ladybugs dislike strong scents like citronella, peppermint, and clove. Mixing a few drops of essential oil with water and spraying it around entry points can act as a deterrent.
Exterior Ladybug Treatment
Perimeter Insecticide: If ladybugs are congregating outside, you can apply an insecticide around windows, doors, and the foundation. Look for pyrethroid-based insecticides like deltamethrin or cyfluthrin. These should be applied in late summer or early fall before the beetles enter the home.
Professional Treatment: If the infestation is severe, our pest control professionals can apply a more effective barrier treatment around your home’s exterior.
Why You Should Get Rid Of Ladybugs In Your Home
While ladybugs are often seen as beneficial insects in gardens due to their ability to control aphid populations, having them inside your home can be problematic. Here are several reasons why people may want to remove ladybugs from their indoor spaces:
Infestation Issues – Large numbers of ladybugs, particularly the invasive Asian lady beetles (Harmonia axyridis), can gather inside homes, especially during the fall and winter months when they seek warmth. These infestations can be difficult to manage and may recur annually if not addressed properly.
Allergic Reactions – Some individuals experience allergic reactions to ladybugs, including respiratory issues, skin irritation, and eye discomfort. Their presence indoors can exacerbate allergy symptoms for sensitive individuals.
Odor and Staining – When disturbed or crushed, ladybugs release a yellowish fluid known as reflex blood, which has a foul odor and can stain walls, curtains, and furniture.
Bites and Skin Irritation – While not aggressive, some species, particularly Asian lady beetles, have been known to bite humans. Their bites are not harmful but can cause minor irritation. See also: Do Ladybugs Bite?
Damage to Indoor Spaces – Ladybugs tend to congregate in warm areas, such as attics, window sills, and wall voids. Over time, their droppings and secretions can create a mess and contribute to unpleasant odors in the home.
Attracting Other Pests – Dead ladybugs can attract other unwanted pests, such as carpet beetles, which feed on organic debris, potentially leading to secondary infestations.
