The Dangers Of Cockroaches In Tucson, AZ homes Homes

September 15, 2021 - Cockroaches

Cockroaches are far too common in the Tucson area. These insects are opportunistic omnivores that are as comfortable in dumpsters or sewers as they are in a box of cereal or perched on a toothbrush. While it is disgusting to think about, think about it we must if we are to protect ourselves from cockroaches. Here are a few things you may not know about the dangers of cockroaches.

Mechanical Vectors

Cockroaches are attracted to rotting organic matter. They don't accidentally get into your garbage cans; they're drawn to them. In your trash or recycling bins, they can pick up harmful bacteria and then transport these microorganisms to sensitive locations. This makes them mechanical vectors for illness-causing bacteria and microscopic parasitic worms. Experts link roaches to the spread of at least 33 kinds of bacteria and 7 species of worms.

Disease Transmission

Cockroaches eat gross things. They can consume an apple or a dead animal that has been rotting in the sun for days. They also feed on the feces of animals and humans. It shouldn't be surprising that they are linked to the transmission of human pathogens. These are spread by the distribution of cockroach feces.


When a cockroach crawls across your skin while you sleep, it could cause you to have a rash. It is possible to have an allergic reaction when you come in contact with a cockroach. Studies have found that cockroach infestations increase issues for those who suffer from asthma. It was found that hospitalizations for asthma symptoms were higher in homes with cockroach infestations.

Property Damage

A cockroach can damage paper products in your home because, like a silverfish, it can digest some forms of cellulose. If roaches infest an area that has wallpaper, they're going to feed on the glue that binds the wallpaper to the wall and also eat some of the wallpaper itself. This can cause your wallpapered walls to become tattered and unsightly. While not a danger to you, it can be a danger to your finances if you desire to repair the damage.

Damage To Your Belongings

Do you know that cockroaches can eat holes in your clothing? It's true. Not only can cockroaches digest cellulose and eat things like wallpaper, but they're also drawn to the scent of perspiration on clothing and they can chew through the fibers of your garments as they chew on a stain of perspiration. If you have garments stored in cardboard boxes, roaches can feed on the cardboard and the clothing stored inside. They'll also chew on important documents, book bindings, newspapers, etc.


Cockroaches don't prefer to eat living tissue. You can have thousands of roaches in your home and not get one bite. It is only when the population of roaches exceeds available food sources that they might take to biting you. One way to tell that you have a high population of roaches is cockroach sightings during the day. These are nocturnal insects that prefer to stay hidden. They only appear when limited food resources drive timid roaches to become bolder.

Another way you may get a cockroach bite is when roaches feed on dead skin in your eyebrows, eyelashes, or around your mouth. If you wake up with a swollen eyelid, a cockroach is likely the cause. This is because roaches deposit bacteria as they bite, and the infection leads to swelling.

Unsavory Behaviors

There are a few things cockroaches are known to do that might disturb you. It is important to keep these in mind.

  • Roaches eat toothpaste and are drawn to the bristles of a used toothbrush. This exposure can lead to a stomach illness.
  • Roaches need moisture. One place they get moisture is from the mouths of sleeping people.
  • Roaches are drawn to the scent of stale or rotting milk. The breath of a sleeping baby can be an attractant.
  • Roaches are highly mobile insects that can go from your trash bin to your food cabinets in a matter of seconds.
  • They scale walls, traverse sealings, and squeeze their bodies to get through gaps that are half their height.

Signs You Have Roaches In Your Tucson Home

If you suspect that your Tucson home has cockroaches, there are a few ways you can tell.

  • Look for black fecal specks in the cabinets under your sinks, or on insulation in your attic spaces.
  • Look for eggs cases in concealed areas, such as behind or under appliances.
  • Look for shed insect skins in dark, damp locations or compressed or tight spaces.
