When Should You Spray For Asian Lady Beetles?

This article provides information on how to eliminate Asian lady beetles, a type of orange bug. To kill the beetles, one can vacuum up, sweep them into a dustpan, or set out a light trap. To kill them, spray them with dish soap, vinegar, rubbing alcohol, or a commercial insecticide.

Prevention is key to getting rid of Asian lady beetles by using spraying. Fast-acting synthetic sprays can be used to kill them, and it is important to keep pets and children away from areas being sprayed until the spray has dried. In addition to liquid insecticide, it is recommended to use an insecticide dust, such as EcoVia WD, around your home to combat Asian lady beetles.

To prevent the beetles from finding a way inside, mix one part water to one part vinegar in a spray bottle. Repairs should be done by the end of September. Use pesticides around doors, windows, and rooflines, and remove the beetles with a vacuum if found in your house.

Starting treatments in late September or early October before the beetles enter buildings to overwinter is crucial. Preventation is the best control method, and fast-acting synthetic pyrethroids like Avesta CS or Cyper WSP can help prevent Asian lady beetles. Vacuuming is also essential, as Asian lady beetles release a scent when threatened. Reapply Supreme IT every 3 months throughout the year, especially during the fall or a month in advance before winter, to repel and kill any Asian lady beetles.

What Is The Best Repellent For Asian Lady Beetles?

Camphor and menthol have been identified in studies as effective short-term repellents for multicolored Asian lady beetles, though their rapid evaporation limits practicality. For immediate removal, vacuuming is suggested. Certain plants, such as chrysanthemums, naturally repel these beetles, making them ideal for gardens or home entry points. To prevent future infestations, clean areas where beetles have left pheromones and use natural deterrents. Wearing gloves is advised to avoid bites.

Natural repellents like peppermint oil, citrus oil, and citronella are recommended for eliminating Asian lady beetles without endangering family or pets. It’s vital to understand these beetles, native to Eastern Asia but widespread in the U. S., to manage infestations effectively. Effective traps, such as the Catchmaster Max-Catch Mouse and Insect Glue Trap, not only kill the beetles but also contain their secretions for easy disposal. Options like spreading whole cloves or spraying camphor or citrus oil can deter these pests by masking their scent trails.

Light traps, including Dynatrap® systems, can attract and capture lady beetles, particularly during their search for warmth in fall. For beetles already indoors, a vacuum, broom, or sticky tape can provide temporary relief. Spraying a mixture of dish soap and water or a strong residual insecticide around exterior windows can also help prevent their entry.

Where Do Asian Lady Beetles Go At Night?

Lady beetles, particularly Asian lady beetles (Harmonia axyridis), start seeking shelter as temperatures drop in September and October. They typically find refuge in cracks, crevices, and corners of attics and garages. Native to Eastern Asia, these beetles are spread throughout the U. S. and are easily recognizable by their red elytra and black spots. Female beetles lay eggs in clusters, averaging 20 to 30 per cluster, and they undergo a complete metamorphosis, which includes egg, four larval instars, a pupal stage, and finally adulthood.

By early October, especially during warm afternoons after cold nights, these beetles gather outside homes, especially those with southern and western exposures that receive ample sunlight. They are attracted to certain volatile chemicals from plants and the pheromones emitted by other Asian beetles. Asian lady beetles thrive in both urban and rural settings, primarily because of their diet, which includes soft-bodied pests like aphids.

During winter, they often congregate in sheltered, sunny areas of buildings, leading them to crawl indoors where they may hibernate in attics and wall voids. Although they do not reproduce indoors, established populations can cause concerns for homeowners. Active management, such as reducing outdoor lighting, may help deter them from entering. Nevertheless, these insects are generally harmless and important for controlling garden pests.

How Long Does Asian Lady Beetle Season Last?

Asian lady beetles actively seek hibernation areas during the cold months, waiting for spring to emerge. Their activity can last until November or early December, depending on when cold weather begins. This time of year is typically not for reproduction, as their mating season has ended; they focus on surviving winter instead. The life cycle of lady beetles is holometabolous, comprising stages from egg, through four instars, to pupa, before becoming adults. Female beetles preferentially lay eggs in places with abundant aphids. Usually, lady beetles produce two broods in a season, but those found indoors typically do not survive the winter.

These insects become particularly noticeable in fall, around Halloween, as they seek warm locations to hibernate. They generally migrate to buildings from September to November based on weather conditions, congregating in protected areas. The average lifespan for Asian lady beetles is more than a year, and they thrive in both rural and urban environments by feeding on soft-bodied pests like aphids, mealybugs, and scales.

Lady beetles prefer to seek shelter when temperatures drop near freezing, becoming active again during warming spells around 64°F. Swarms may appear on homes, especially on light-colored walls in sunlight. The beetles generally do not endure winter in homes; hence, the numerous multicolored Asian lady beetles spotted in homes often last until spring without reproducing. Their lifecycle completion from egg to adult takes approximately 15 to 25 days, with various stages lasting different lengths.

Can I Use Insecticide Dust To Kill Asian Lady Beetles?

To effectively combat Asian lady beetles, it is recommended to use a combination of liquid insecticides and insecticide dusts like EcoVia WD around your home.
