Understanding Ladybugs and Their Behavior
Ladybugs, also known as lady beetles or ladybird beetles, are beneficial insects in outdoor settings. They help control garden pests, making them a gardener’s friend. However, during colder months, particularly in fall, ladybugs seek warm, dry places to overwinter a hibernation-like state where they live off their energy reserves. This behavior often leads them into homes, where they enter through small cracks, windows, doors, vents, or even houseplants.
It’s important to distinguish between native ladybugs and Asian lady beetles (Harmonia axyridis), which are often mistaken for one another. Native ladybugs are less likely to invade homes, while Asian lady beetles are more aggressive and prone to entering in large numbers. You can identify Asian lady beetles by a small “M” or “W” marking on the shield-like section behind their head. Both types use pheromones to communicate, meaning once one finds a cozy spot in your home, others may follow, leading to a ladybug infestation.
What Attracts Ladybugs to Your House?
Before we dive into solutions, let’s look at the problem. Why are ladybugs choosing your house in the first place?
- Warmth: Ladybugs are drawn to warm places, especially in the fall.
- Light-colored walls: Homes with light siding or lots of sun exposure are particularly appealing.
- Cracks and crevices: Tiny openings in walls, windows, or roofs are prime entry points.
- Shelter: Ladybugs seek safe spots to hibernate during winter.
Understanding what draws them in is the first step to kicking them out.
Are Ladybugs Harmful?
Ladybugs are generally harmless to humans. They do not sting, and while they can bite, it’s rare and feels like a mild pinch. However, some individuals may experience allergic reactions, particularly during peak infestation periods in fall and winter, which can exacerbate conditions like hay fever or skin sensitivities. Additionally, when stressed, ladybugs release a yellowish fluid through reflex bleeding, which can stain walls, furniture, or upholstery and has an unpleasant odor. While this fluid is harmless, it can be a hassle to clean.
Using indoor insecticides to eliminate ladybugs is not recommended due to potential health risks, such as respiratory issues. The Environmental Protection Agency advises minimizing indoor pesticide use, making natural and physical removal methods preferable.

Methods on How to Get Rid of Ladybugs in House
Several safe and effective methods can help you remove ladybugs from your home while preserving their role in the ecosystem. These methods range from physical removal to natural repellents, with chemical options as a last resort.
Physical Removal
Physical removal is the most humane way to handle ladybugs, allowing you to relocate them outdoors where they can continue benefiting your garden.
- Sweeping and Vacuuming
Use a broom and dustpan to gently sweep ladybugs into a container for release outside. Alternatively, use a vacuum cleaner with a hose attachment, ideally with a sock or stocking over the hose to trap them without harm. Empty the vacuum canister immediately outside to prevent odor buildup, and wash the affected area with soapy water to remove pheromone trails that attract more ladybugs. - Duct Tape Trick
Wrap duct tape around your hand with the sticky side out and gently press it against areas where ladybugs gather, such as windowsills or walls. This method allows you to pick up and relocate them. You can also place strips of duct tape sticky-side up as traps, checking and replacing them regularly. - Light Traps
Ladybugs are attracted to light, making light traps an effective solution. Create a DIY trap by cutting a 2-liter plastic bottle in half, placing an LED light in the bottom half, and inverting the top half to form a funnel. Place the trap in dark areas where ladybugs congregate, check it regularly, and release captured ladybugs outdoors. Commercial light traps, like the Zevo Flying Insect Trap, can also work.
Natural Repellents
Natural repellents are safe for your household and the environment, leveraging scents and substances that ladybugs find unpleasant.
- Dish Soap Spray
Mix a few drops of dish soap with water in a spray bottle and apply it directly to ladybugs. The soap disrupts the water’s surface tension, suffocating them. Alternatively, place shallow bowls of this mixture near light sources, such as windows, to trap ladybugs. - Diatomaceous Earth
Sprinkle food-grade diatomaceous earth around windows, doors, and other entry points. This natural powder dehydrates insects, acting as both a deterrent and a lethal barrier. It’s safe for humans and pets but should be used cautiously to avoid harming other beneficial insects like honeybees. - Planting Chrysanthemums (Mums)
Chrysanthemums emit a scent that repels ladybugs. Planting mums around your home or porch in the fall can deter ladybugs from approaching. For indoor protection, place mums in window boxes. - Bay Leaves and Cloves
Crush bay leaves or place whole cloves near windows, doors, and pantries. Their strong aromas repel ladybugs effectively. You can also create small sachets of these items for easy placement. - Essential Oils
Essential oils like citronella, lavender, lemon, or orange can deter ladybugs. Mix a few drops with water in a spray bottle and apply to entry points, or use citronella candles near doors and windows. Wiping down surfaces with citrus oil solutions can also create a repellent barrier. - Vinegar Spray
Combine equal parts white vinegar and water in a spray bottle. Spray this on surfaces where ladybugs travel to neutralize pheromones and kill them on contact. This also acts as a natural insecticide.
Chemical Repellents
For severe infestations, store-bought insecticides labeled for ladybugs or multi-insect traps may be considered. However, use these with caution, especially indoors, due to potential health risks. Always follow label instructions, wear protective gear (gloves, mask, goggles), and ensure proper ventilation. Outdoor insecticides can also be applied around your home’s perimeter, but confirm they are safe for pets, children, and plants.

|---|---|---|
| Color | Bright red | Orange to yellow-orange |
| Spots | Distinct black spots | Fewer or none |
| Behavior | Mellow | Aggressive, may bite |
| Smell when disturbed | Mild | Strong and unpleasant |
Knowing the difference can guide your response. Asian lady beetles are more invasive and often require more serious action.

What is the best way to get rid of a lady bug infestation
Prevention is the most effective way to avoid ladybug infestations. Here are key steps to keep them out:
- Seal Entry Points: Use waterproof silicone caulk or expanding foam to seal cracks around windows, doors, siding, and foundations. Inspect your home in early spring and fall to catch potential entryways.
- Install Window Screens: Ensure all windows have tight-fitting screens, and repair any tears with clear nail polish or sewing. Consider professionally fitted screens for optimal protection.
- Apply Weatherstripping: Use peel-and-stick weatherstripping on doors to minimize gaps, which also helps with energy efficiency.
- Cover Vents: Install mesh covers on vents and dryer vents to block ladybug entry.
- Inspect Houseplants: Before bringing plants indoors, check them thoroughly for ladybugs, as they can hitch a ride inside.
Regular maintenance and vigilance, especially in the fall, can significantly reduce the likelihood of a ladybug infestation.
