Here is an interesting use for the fake flowers you see decorating businesses. Fake flowers are loaded up with drugs that reduce diseases like malaria and West Nile. The mosquitoes are attracted to the flowers and ingest the medicine from the flower. This reduces the virus in the mosquitoes so that even if you get bitten there is not enough virus in the bite to make you ill.
…The most common way of fighting diseases like malaria, dengue fever, and West Nile today is to try to wipe out the mosquitoes carrying them and treat those who have been infected. Now there’s an alternative on the horizon that promises to be safer and cheaper by zapping the germs while sparing the mosquitoes. The technology is hidden in an artificial flower designed to attract mosquitoes and treat them with pathogen-killing drugs that allow the insects to live and continue to perform important functions such as pollinating flowers and serving as food for animals and other insects.
