If your goal is excluding small
insects, you should select a small opening insect screen. |

When selecting the
opening specification one very important aspect should be
considered, the 'Diagonal Length' of the opening. The diagonal
length is considerably larger than the width. To view the diagonal
length click on the PDS

Insects have
three
main body parts, the head, the Thorax and the Abdomen. The
head is smaller than the Thorax or the Abdomen. When an insect
approaches an obstacle, crack or any type of restricted
opening (such as an insect exclusion screen) the head is the first
part that is inserted (unless the intent is laying eggs) or
attempted to insert, once the head succeeds in passing through the
restriction the insect now believing the passage is possible,
no effort will be spared to complete the task. |
 |
|
The intruder will
then attempt to insert its legs in order to pull the Thorax (to
which the legs are attached) into the crevice, crack or restriction.
If the legs fail to pass through the restriction, the insect will
continue the effort by removing and reinserting its head while
rotating (or vibrating) its Thorax and Abdomen making multiple
attempts to pass through the restriction at every possible angle of
approach |
|
Assuming the Thorax
achieves passage (more likely after the legs have been sheared or
chewed off) the Abdomen being the ultimate challenge, may
unfortunately be sacrificed and left behind......insect suicide.
