I got an email on this, and am assuming it's true. If so, it's something to consider!
FYI...
Be careful if you plan to buy mulch this summer...
If you use mulch around your house, be very careful about buying mulch this year. Hurricanes Katrina and Rita blew over many trees in New Orleans. These trees were then turned into mulch. Louisiana is trying to get rid of tons and tons of this mulch to any state or company who will come and haul it away.
It will probably start showing up in Home Depot and Lowes at cheap prices. There's just one huge problem - Formosan Termites will be the bonus in many of those bags. New Orleans is one of the few areas in the country where the Formosan Termites have gotten a strong hold and most of the trees blown down were already badly infested with these termites. These termites can eat a house in no time at all and we have no good control against them.
Tell your friends that own homes to avoid using mulch that doesn't state where it came from or if it came from New Orleans.
