1. A pesticide release device configured for delivering a vaporizable and/or sublimateable pesticidal composition in vapor form to a pest habitat that includes:
a container that is configured to store the vaporizable and/or sublimateable pesticidal composition; and
a rigid vapor injector comprising:
a first segment that defines a height between a proximal end that is narrower than a distal end that includes a mating portion, and
a second segment that defines a height between a proximal end that includes a first mating portion that is configured to mate with the first segment and a distal end that includes a second mating portion that is configured to mate directly to the container that is configured to store the vaporizable and/or sublimateable pesticidal composition,
wherein the first segment and the second segment have respective heights of no greater than 25 cm,
wherein when the vapor injector is in an assembled configuration there is a chamber internal to both the first segment and the second segment,
wherein a plurality of apertures are disposed along respective outer surfaces of both the first segment and the second segment of the vapor injector, are in communication with the chamber, and are configured to allow the vaporizable and/or sublimateable pesticidal composition to flow from the chamber directly into the pest habitat when the device is in an assembled configuration,
wherein the outer surface of the first segment is tapered along the entire height of the first segment, and
wherein the outer surface of the second segment is tapered along the entire height of the second segment.
