How long does permethrin remain repellant to bed bugs?
|
|
|
| Same situation as before, but slightly different question - how long will
the permethrin keep bed bugs off a surface?
Recap:
I've been spraying for bed bugs, using water dilution of "insectrin X"
permethrin and concentrations between .3 and .6 %. (Gentrol was mixed
in, too.)
How long does the repellant effect of permethrin last:
1) on carpet
2) on unpainted wood.
3) on painted (latex) wood.
4) on painted drywall
5) on bare metal?
I spray fairly liberally.
So far I've sprayed the box frame inside and out and edges of mattress
(twice), creases and seams of sofa, floor around sofa and bedroom floor
and closet, each time airing out for several hours with external air
blowns through the sprayed area.
The bites seem to have stopped for the last 2 weeks.
(Note that I'm in new construction, no real cracks or crevices around for
dusting.)

"Insectrin X" 10% permethrin, diluted with water to 0.3 percent. Sprayed until
carpet surfaces damp, others wet.

AFAIK it is not very repellent to bed bugs - if it were they wouldn't
walk treated areas, would they?
Although highly repellent to some ants (and one of the best if your aim
is to spread german cockroaches all over the place), I've never heard
that permethrin would repel bedbugs.
