Do all the kissing bugs have it when they were born or do they get these parasites from external sources? I’ve seen some on my front porch and I’m worried for my family.
Kissing bugs most likely get it from external sources but it could be passed on; insufficient data is available to know for sure. Kissing bugs feed on blood and during the process may ingest whatever contents (good or bad) the host has circulating throughout their body. Similar to how DEER TICKS get lyme disease and transmit the spirochete to people so too do the Kissing Bugs transmit the flagellate protozoan to people when feeding.
The good news is this disease has not been reported here in the States and the problem seems to be in kissing bug species located throughout Mexico, Central and South America. Kissing bugs are attracted to lights and feed at night. If you are burning an exterior light around the home, it could be a “welcome beacon” to any nearby.
