Large numbers of lady beetles ladybugs infesting homes and buildings in the United States were first reported in the early s. Ladybugs normally are considered beneficial "Huge asians holes" they Huge asians holes outdoors and feed on plant pests. Once inside they crawl about on windows, walls, attics, etc. In many areas of the U. The beetle is native to Asia e. The first field populations in the United States were found in Louisiana in Since then the beetle has expanded its range to include much of the U.
Earliest records in Kentucky date back to a few specimens collected in Hickman County in the s to s, the U. Department of Agriculture attempted to establish the Asian lady beetle to control agricultural pests, especially of pecans and apples.
No such releases were ever attempted in Kentucky, and their occurrence here is probably due to northward migration from other southern states. Some scientists believe that current infestations in the U. Their color can vary widely from tan to orange to red. They often have several black spots on the wing covers, although on some beetles the spots may be indistinct or entirely absent. Multi-spotted individuals tend to be females while those with few or no spots tend to be males. Most beetles have a small, dark "M" or "W"-shaped marking on the whitish area behind head.
Eggs are yellow, oval, and typically are laid in clusters on the undersides of leaves. The immatures larvae are often orange and black and shaped somewhat like tiny alligators.
Larvae complete their development on plants where their primary food aphids is abundant. The Huge asians holes cocoon pupal stage remains attached to vegetation by its molted skin, but occasionally may be found clinging to exterior walls of buildings. The average time from egg to adult is about one month and
Huge asians holes are multiple generations per year.
Individual beetles can live up to three years. At present, Asian lady beetles appear to have few natural enemies. As a defense against predators, the beetles secrete a foul smelling yellowish fluid from their leg joints when disturbed. Some mortality occurs at sub-freezing temperatures, although survival is enhanced within buildings and other protected locations if adequate moisture or humidity is available. In its native land, the Asian lady beetle is mainly tree-dwelling, living in forests and orchards.
In Japan, it is also abundant in soybean fields. During spring and summer, the larvae and adults feed mainly on aphids, consuming hundreds per day.
As autumn approaches, the adult beetles leave their summer feeding sites in yards, fields and Huge asians holes for protected places to spend the winter. Unfortunately, homes and buildings are one such location. Swarms of lady beetles typically fly to buildings in September though November depending on locale and weather conditions.
In Kentucky, most migration to buildings occurs in October. Beetle flights are heaviest on sunny days Huge asians holes a period of cooler weather, when temperatures return to at least the mids. Consequently, most flight activity occurs in the afternoon and may vary in intensity from one day to the next. Studies have shown that Asian lady beetles are attracted to illuminated surfaces. They tend to congregate on the sunnier, southwest sides of buildings illuminated by afternoon sun.
Homes or buildings shaded from afternoon sun are less likely to attract beetles. Contrasting light-dark features tend to attract the beetles -- dark shutters on a light background, light shutters on a dark background, windows edged with light-colored trim, gutters and downspouts on contrasting siding, etc.
Dwellings near woods or fields are especially prone to infestation, although those in other locations can be infested as well. Once the beetles alight on buildings, they seek out crevices and protected places to spend the winter.
They often congregate in attics, wall cavities, and other protected locations. Typical locations include cracks around window and doorframes, behind fascia boards and exterior siding, and within soffits, attics, and wall voids. Structures in poor repair with many cracks and openings are most vulnerable to infestation. This usually occurs first on the sunnier, southwest side of the building.
As awakening beetles attempt to escape to the outdoors, some inadvertently wander inward, emerging from behind baseboards, walls, attics, suspended ceilings, etc. Since lady beetles are attracted to light, they are often seen around windows and light fixtures.
Asian lady beetles generally do not injure humans and are mainly a nuisance. Unlike some household pests e. Lady beetles do not attack wood, food or clothing. Nonetheless, some householders detest finding any insects indoors, and hygienic establishments such as hospitals have zero tolerance for contaminants of any kind.
Besides being a nuisance, the beetles emit an acrid odor and can stain surfaces with their yellowish secretions when disturbed volatile compounds used in defense against bird and other vertebrate predators. People should avoid touching their eyes after handling the beetles, and should consult a physician if they suspect they are having an allergic Huge asians holes. When large numbers of beetles are flying in the fall, they often land on clothing and Huge asians holes will bite or
Huge asians holes if in contact with skin.
In nature, lady beetles eat other insects and have chewing mouthparts. The bite feels like a pinprick and is seldom serious. Asian lady beetles are also becoming a concern of the wine industry. Due to their noxious odor, even small numbers of beetles inadvertently processed along with grapes can taint the flavor of wine. People's reaction to lady beetles varies widely
Huge asians holes tolerance to revulsion.
The following management tips are provided when the beetles become a serious nuisance within a dwelling. Once the beetles are indoors, the easiest way to remove them is with a vacuum cleaner.
If you later wish to release the beetles outdoors, place a handkerchief between the vacuum hose and the dust collection bag to act as a trap. A broom can also be used, but is more likely to result in staining when beetles emit their yellowish defensive secretion.
Sealing cracks and openings is the most permanent way of preventing lady beetles from entering buildings. The time to do this is in late spring or summer, before the adults begin flying to buildings in search of overwintering sites. Cracks should be sealed around windows, doors, soffits, fascia boards, utility pipes and wires, etc. Larger holes "Huge asians holes" be plugged with cement, urethane foam "Huge asians holes" copper mesh.
Repair damaged window screens and install screening behind attic vents, which are common entry points for the beetles. Install tight-fitting door sweeps or thresholds at the base of all exterior entry doors. Gaps under sliding glass doors can be Huge asians holes with foam weather stripping. These practices will also help prevent entry of flies, wasps, crickets, spiders and other pests. Some householders may find it more practical to hire a pest control firm, building contractor or painter to perform these services For more on this topic see University of Kentucky entomology fact sheet, How to Pest-Proof Your Home.
Insecticides applied indoors for lady beetles tend to be ineffective and may stain or leave unwanted residues on walls, countertops and other surfaces. A vacuum Huge asians holes more sanitary and effective. Attempting to kill beetles hibernating in wall cavities and other protected locations is seldom effective. A better approach is to take preventive measures to reduce beetle entry in subsequent years.
There can be countless cracks associated with eaves, siding, vents, etc. On multi-story buildings, sealing becomes even more difficult. If lady beetles are a perennial problem, owners may want to hire a professional pest control firm. Many companies apply insecticides to building exteriors in the fall, which helps prevent pest entry. Fast-acting residual insecticides be sprayed in a targeted band around windows, doors, eaves, soffits, attic vents, and other likely points of entry.
Some of the more effective insecticides used by professionals include Demand lambda cyhalothrinSuspend deltamethrinTalstar bifenthrin and Tempo cyfluthrin. Purchasing these products in concentrated dilutable form will allow larger volumes of material to be applied with a pump-up or hose-end sprayer. To be effective, barrier treatments should be applied before the beetles enter buildings to overwinter. In Kentucky, the proper timing
Huge asians holes such treatments is typically late-September to early October although this will vary with seasonal conditions.
During late winter or early spring, barrier treatments are ineffective since the beetles gained entry the previous autumn. Other approaches have been suggested to alleviate problems with Asian lady beetles. Ladybug "houses" sold in garden supply catalogs will have no effect in keeping the beetles out of your home.
Light traps be useful for capturing flies and lady beetles in dark confined spaces
Huge asians holes as attics, but will capture relatively few beetles entering living spaces in the fall or emerging from hidden locations the following spring. Unfortunately, there is no "quick fix" or easy answer to annual lady beetle invasions. Vacuuming, pest proofing and properly timed exterior insecticide treatments can provide relief but will not prevent entry of every single beetle.
The use of some products may not be legal in your state or country.
