7.Ants are troublesome,best known for itchy bites and ruining picnics.But,a new species of crazy ant is taking over Texas.In some ways they appear to be worse than fire ants and there's no good way to stop them.These ants move fast and are plentiful in some areas.
The crazy ants first sprang in Pearland in 2002 and have been becoming more and more of a problem ever since."An invasion of these can be so extreme that it's hard to call it just a nuisance,"University of Texas entomologist Edward LeBrun told The Austin American-Statesman."The ants have been known to crawl into and ruin televisions,appliances and other electronic devices.No one is entirely sure why,"He said.
David Oi,a research entomologist at the Department of Agriculture,told The New York Times in 2013,the strange idea that the ants are actually attracted to the electricity itself can't be ruled out.
The crazy ants or Raspberry ants-yep,that's actually what they are called-are found in 23 Texas counties.The ants have very little venom(毒液),but do cause a slight sting when they bite.Mostly,though,they're a hazard to electrical equipment.
They are a relatively new species in the region and little is known about how to control or kill the population.And,unfortunately,there doesn't seem to be much that can be done about them right now.So,for the moment,the best advice is not to stay close to ant piles and groups,and hope that none make it inside to crawl around the electronics.
