Panstrongylus geniculatus lives mainly in humid forests and in animal nests such as armadillos, but it is increasingly found inside homes and around houses. It is present in at least 16 Latin American countries, including Venezuela, Colombia, Brazil, Peru, Ecuador and Argentina. The bug feeds on blood and many individuals carry the parasite Trypanosoma cruzi, the cause of Chagas disease.

Is it a pest in the house?

The species is in the process of domiciliation, similar to highly domestic triatomines. Its spread into domestic and peridomestic habitats has drawn attention because it can transmit Chagas disease.

Does it bite or sting?

It is considered a minor vector of Trypanosoma cruzi, the parasite that causes Chagas disease. A study in Venezuela found that about 76 % of examined specimens were carrying T. cruzi in their feces.

How this page works

This is one bug's fact sheet. The colored box at the top says whether it is dangerous. Sections below cover how to recognize it, whether it is a pest, and how to deal with it. The US map shows which states have records; tap a state to see other bugs there.

Every fact on Bug FAQ comes from a named source (university extension sites, government agencies, GBIF, iNaturalist, Wikipedia). The source is linked next to each section. If we have no source for something, we leave it out.
