1 . An insect controlling smoke detector device, comprising:

a housing having a smoke detecting chamber formed therein;

a light source directing a light beam through the smoke detecting chamber;

a light sensor to receive a portion of the light beam and analyze the received light beam to determine whether smoke particles are present in the chamber;

an insecticide release apparatus located in air communication with the smoke detecting chamber via a conduit that creates airborne insecticide within the smoke detecting chamber to cause any insects therein to become detached from an inner surface of the smoke detecting chamber thereby clearing any insects therein from a path of the light beam through the smoke detecting chamber; and

a fan located within the conduit between the insecticide release apparatus and the smoke detecting chamber to:

move the insecticide from the insecticide release apparatus into the smoke detecting chamber;

move the insecticide around within the smoke detecting chamber; and

move the insecticide out of the smoke detecting chamber after the insects therein have become detached from the inner surface of the smoke detecting chamber.

2 . The insect controlling smoke detector device of claim 1 , wherein the insecticide is embedded in a solid.

3 . The insect controlling smoke detector device of claim 1 , wherein the insecticide is embedded in a wax material.
