Many
of the grain pests will also attack manufactured foods
such as flour, chocolate, soup mixes, pasta, instant
chinese meals, semolina,oats, etc. These products
can easily become infested through cross contamination
when the products are transported in trucks, stacked
on infested pallets or stored near other infested
product in storage.
Ideal
temperatures for infestations of stored product pests
to flourish is between 20 to 30 degrees C. Most species
of stored product pest have a very short lifecycle
(four weeks). This means that small infestations on
delivery can become major infestations within moths
causing considerable stock loss.
The temperatures together with high humidity created
by these pests can sometimes lead to the outbreak
of fire.
