Status |
|
|
|
|
Closely associated with man, this species is
widespread throughout the northern hemisphere and Europe in particular. H. pseudospretella requires a high proportion of animal protein in
it's diet including feathers, wool and hair - a diet which is reflected in its behaviour
as a scavenger. |

Widespread and common in both domestic
situations and food storage environments. Of particular note in food preparation and
museum surroundings where it's presence may pose a threat to public health and stock.
Occurrences may be linked with birds nests. |

Control |
|
|
|
|
Complete metamorphosis life cycle. Eggs
are laid singly within the food substrate. Hatch occurs between 10 and 40 days
depending upon conditions. Larvae produce silken tunnels within the substrate and
may exist 2 - 5 months before pupation. Diapause may extend the effective length of the
life cycle. |

|
|
|
Removal of birds nests, and general aggregations
of food / organic matter are recommended. Frequent vacuuming of these areas will
reduce the breeding potential by physical removal of all stages in the life cycle.
Where appropriate, use of a residual insecticide spray will provide control. |
