Pest allergies caused by stinkbugs and ladybugs overwintering in your home may cause similar symptoms to Covid-19, the flu and the common cold. Moving into the cooler months and influenza season of 2020 is causing Americans to worry that it will be difficult to determine what disease or reaction they are having. Covid-19, the flu, a common cold and pest allergies share a lot of similar symptoms. Without a few key indicators or a test you may not know for sure which one it is.

The main difference, between Covid-19 and the flu, is the loss of smell and taste. Losing this sensation is one of the many wacky symptoms that can accompany the Covid-19 infection. This medical phenomenon is called anosmia.

Dealing with invasive pests in the fall months can not only cause an annoying distraction with crawling insects all over your ceiling, but can also cause some alarming allergic reactions that mimic the flu and Covid-19.  After pest allergies progress, the later stage symptoms do not develop into the same alarming signs as the flu or Covid-19.
