Why Cockroaches Are Sometimes Found In Toilets, Bathtubs And Sinks

The relatively mild winter climate and mountainous landscapes in southern Arizona make the region an ideal place to live for many people. Unfortunately, Arizona is also home to a large number of cockroach species that invade houses where they often establish a sizable infestation. The most common cockroach pest species worldwide can all be found in Arizona, including American, Oriental and German cockroaches. A few other species, like the desert cockroach, maintain a habitat solely within the desert southwest, and other species in the state, such as brown-banded, Turkestan and Surinam cockroaches, live in habitats that are limited to the southern US.

Cockroaches have adapted to living within human dwellings, and they are capable of exploiting a variety of access points in order to invade houses. This is especially true when it comes to domestic cockroach species, like German and brown-banded cockroaches, that dwell primarily within structures. The peridomestic cockroach species, the 2 inch American cockroach, is even capable of traveling through sewage pipes in order to enter houses through drains, and once inside, cockroaches expertly navigate indoor areas to gather food and maintain a safe shelter. Despite being well adapted to thriving indoors, many residents have found cockroaches struggling to escape toilet bowels, bathtubs and sinks.

As anyone can understand, people are perplexed upon finding cockroaches in their toilet. This sort of discovery begs the question as to how cockroaches can wind up in a toilet. Finding cockroaches in a sink makes more sense, as sinks often contain food scraps that cockroaches seek, but roaches are often found in bathtubs and sinks that are completely clean. The cockroaches found in toilets, sinks and tubs are most likely Oriental cockroaches. These cockroaches are not capable of flight and they move slowly and sluggishly. Oriental cockroaches cannot climb vertical surfaces well, and when they fall into sinks, tubs and toilets, they are unable to escape due to the smooth surface. Since cockroaches prefer moist conditions, it is not surprising that they often gravitate into bathrooms, and while finding roaches in a toilet may be perplexing, a toilet is probably the best place to find cockroaches within a home.
