[2] Inhabiting warm, dry climates, T. sordida are widely distributed throughout South America, occupying houses, farming structures, and wild habitats.

[9][10] Triatoma sordida have sucking mouthparts used to gain external access to their blood host and two sets of membranous, overlapping wings.

In addition, stridulation, or sound production, may be achieved by rubbing the proboscis against a grooved organ located on its ventral surface adjacent to the head.

[14] Although, recent work utilizing scanning electron microscopy (SEM) technology, has allowed researchers to photograph and characterize external anatomy to assist in species identification.

[17] Laboratory studies confirm the success of a pyrethroid insecticide, called deltamethrin, as a control for T. sordida, as long as the treatment is applied twice.

As a result of findings of a new fungal species of Evlachovaea on deceased Triatoma sordida, researchers investigated the viability of this fungi as a biological control agent.

[5] Their findings suggest that Evlachovaea can increase mortality of third-instar Triatoma sordida nymphs, but only if humidity is favourable to fungal production.
