Black Vengeance Lady Beetle Traps
Southeastern Insectaries has developed a highly efficient trap for removal of nuisance lady beetles from homes or other infested buildings. The trap works within darkened rooms and is best suited for use at night while the occupants sleep. The trap may be used during daytime provided the room is completely dark and unlighted by windows or other light sources. The trap attractant is ultra violet radiation known as black light emitted by 15 watt fluorescent lamps of the type found in tanning parlors. The trap is most efficient when room temperature is warm (from 75-85 degrees Fahrenheit)and is less effective at temperatures below 68 degrees. Two versions of the trap are available: the 180 trap and the 360 trap. These numbers imply the direction of illumination by each trap. Thus the 360 trap attracts from all directions surrounding the trap while the 180 trap attracts from only 180 degrees. The traps are identical except that the 360 has two lamps and the 180 has only one lamp. Traps are supplied with talcum powder which is used to coat all vertical surfaces. Talc prevents attracted beetles from clinging to vertical surfaces and they fall to the bottom of the bucket where they become trapped. SEI traps are not designed to kill lady beetles but rather to collect them for removal from the building. Beetles are removed from the trap bucket by pouring them into a container that can be sealed, such as a plastic bag or cage. The beetles can then be released outside, discarded or destroyed.
SEI black light traps are designed for use only on the inside of buildings or beneath a covered porch.
The traps are not designed for use out of doors, or where
they may become wet or damp.
BEHAVIOR OF LADY BEETLES
Multicolored Asian lady beetles, Harmonia axyridis, are important as natural controls for many kinds of aphid pests on a wide variety of plants. They are especially useful for control of aphids on fruit, ornamental and forest trees. For this reason they are abundant in and around heavily wooded areas such as fruit and nut orchards, parks, and forests. Lady beetles do not breed during the winter hibernation period when they are a nuisance in houses. They only breed from springtime to late summer when they feed on aphids in the field. Immature Asian beetles look like tiny black and yellow (to orange) alligators. The eggs of lady beetles look like tiny yellow footballs in clusters of a few to 30 or more. Eggs and immatures are found only on the foliage or bark of plants and trees. In middle Georgia, around November 1, adult lady beetles begin migration-hibernation flights when they seek protected places to spend the winter. They are particularly attracted to light-colored structures with sunny southwestern exposures. For this reason they aggregate in large numbers on the sides of houses, barns and other buildings that are not shaded by trees. Aggregating beetles first crawl around on the outside of the building seeking an entrance. Entrances are often found beneath facing boards around windows and doors, cracks between siding, unscreened vents and louvers, faulty weather strips around doors, and through the cracks associated with roof flashing and overhang. Here they gain access to attics, basements, walls, and even chimneys. If the building is not heated, the beetles usually settle down into large clusters where they remain until spring approaches in February or March. The aggregation period is when they first become a nuisance. Later during the winter, in buildings where temperatures are comfortable for human habitation and especially on days that are unreasonably sunny or warm, some of the beetles become active and work their way into the interior of the building where they become a nuisance for the second time. These fly and crawl about ending up at window sills while trying to escape, where they eventually die from exhaustion. During springtime, beetles that successfully hibernated become a nuisance for the third period when they try to return outside. The black light traps offered for sale by SEI have been found very effective for removing Lady beetles during the three nuisance periods.
