Washington (AP) Spring has arrived and daylight savings time is right here, so can the mosquitos be far behind? For many Americans, it is time to get out the electric bug zapper. The continuous snap, crackle & pop coming from a zapper on a summer season evening has convinced many homeowners the traps are efficient in ridding porches and patios of marauding mosquitos and no-see-ums. But wait, say some scientists who examine insects. Too usually, they believe, bug zappers not only are ineffective against biting bugs, however do extra hurt than good. Nearly half had been non-biting aquatic insects such as caddis flies and midges that feed fish, frogs, birds and bats, the research found. And another 14 % had been insects that actually assault pests, corresponding to wasps, ground beetles and ladybugs. Douglas W. Tallamy and Timothy B. Frick, who conducted the examine. Tallamy, an entomologist, mentioned insects have been described as the glue of the ecosystem. Sal DeYoreo, president of Flowtron Outdoor Products, a producer of electric traps in Melrose, Mass., disputed the Delaware study. The Delaware study estimated that about 1 million zappers are bought in the United States every year. The traps used within the project had been working for a mean of seven years.
