Pheremone ladybird traps really don't | work -- or they do work moderately well for sampling during spring | breeding, but that's not useful for getting rid of lots of them or for | house invasions when they're trying to hibernate, not reproduce. But | light-traps do work very well under specific conditions. | | Most of these light-traps incorporate one to several flourescent black | lights, which require starters & ballasts, which I'm not sure are ever | battery-operable, but maybe. You wouldn't need a lot of them, as the traps | are useful only in capturing the ladybugs during their mass-overwintering | when they might invade homes or garages where they cannot go completely | dormant due to the spaces being heated; or to get them out of interior | walls of heated homes. | | The traps only work on warm days after the ladybugs have gathered. Since | they tend to gather when warm days are over, the traps turn out to be | useless in the unheated outdoors where the ladybirds do go completely | dormant. | | Light traps as tested at Ohio, Georgia & Florida universities are VERY | reliable in capturing warmed winter gatherings of ladybirds from enclosed | areas where all other light sources (including starlight or streetlight | through windows) has been extinguished or well-blocked. The traps do not | harm the insects, nor even cause them to release their protective smell as | vaccuuming does. | | Here's a PDF file from USDA about black light traps for ladybugs: |

|| Some of the commercially made ones like Cooperseeds' product are very | pricy ($65 to $140 for the device). If one didn't have an ongoing use for | such a trap, it would be too much to pay. This one is cheaper: |

| but the company discussed, H&T Alternative Controls, seems to have no | website, only an address, phone & fax. The H&T Alternative trap seems to | be a variation of the Ohio State University ladybird trap, which can be | built at home for next to nothing. | | Some vendors of the expensive ultraviolet traps state that incadescent | visible-light traps aren't as good, & the USDA seems to back that up. But | Ohio State University has reported on tests of their own incadescent bulb | trap which they say works very well, & it has the significant "plus" that | you can make it for about $10 without any skills at making things, with a | hanging light fixture, a couple of plastic milk bottles, some black paint, | & talcolm powder to make the sides of the milkbottles unclimable. Here's | the plans: |

| Same as with ultraviolet traps, it won't work on an open porch or when it | is cold; it will work after a warm day, generally indoors, in a space that | has no other light source. In those conditions, any of the light traps can | capture nearly all the ladybirds without harming them. | | -paghat the ratgirl | | -- | "Of what are you afraid, my child?" inquired the kindly teacher. | "Oh, sir!
