The US is suffering through a
resurgence of bedbugs and the itchy
welts their bites cause. So now,
some health officials are asking
the Federal EPA to bring back an
old pesticide. Bill Cohen reports:

Complaints to pest control firms about bedbugs have tripled in 4 years.

Two reasons. More people are scavenging infested mattresses thrown out on the street. Plus, the bugs are getting resistant to current pesticides.

That’s why Ohio is asking the feds to let home exterminators use propoxur. Red tape and questions over possible side effects like nausea shelved the pesticide years ago, but local health official Paul Wenning fears, without it, frustrated itchy homeowners will turn to more dangerous weapons to fight the bugs.

“Our greatest fear is that someone is going to get ahold of some old pesticide – like DDT or something – are going to treat their house, and we’re going to have a lot of very sick and possibly dead people.”

Ohio expects other states will join the drive to bring back propoxur.

Researchers are working on new chemicals
to keep mosquitoes from biting. The Environment
Report’s Mark Brush reports they might have found
a better alternative to DEET:

The EPA says DEET is safe to use on your skin. But the repellent’s smell and stickiness
turns some people off. And spraying DEET on your skin won’t protect you from all types
of mosquitoes.

So researchers are working on alternatives.

Uli Bernier is research chemist with the USDA. He says their research team is looking
for a compound that will work against some of the most dangerous mosquitoes.

“DEET works against a great variety of insects, but not against all of them. And in
particular some of the malaria transmitting mosquitoes will bite through DEET without
difficulty.”

Bernier says their research has turned up some chemicals that do a better job than DEET.
The chemicals keep mosquitoes from biting for up to three times longer. Bernier says their
next step will be to test the chemicals for possible human health effects and for their
effectiveness on other insects.
