which gives the mites more options for
hiding. "Some studies have shown that
mite infestation rates in traditional
cage systems are lower than in alternative systems; however, some places in
the world have very high infestation
even in cages," Flochlay said.
There are premise insecticides that
will kill poultry red mites that can
be used in non-poultry contact areas.
However, those products and their
availability vary in different countries,
she explained. Most of them do not offer a recommended withdrawal time,
which is why they can't be used in the
presence of the birds. This may create
a consumer safety issue for meat and
eggs, she added.
Some non-chemical methods are
being used to try and control poultry
red mites, but these often don't give
adequate control. Often these methods result in a reduction to the number of mites but do not fully remove
them, she explained.
In some cases predator beetles
and mites have been introduced to the
houses infested with poultry red mites,
but results have been inconsistent.
There are insecticides that can
be used in bird living areas that have
some impact on various life stages
of the poultry red mite. However,
they must be government-approved,
and in the case of Byemite, a concentrated emulsion containing
phoxim, and organic phosphate,
eggs laid during and after treatment
for 12 hours must be destroyed.

"I'm not aware of any feed additives that help control poultry red
