A recent report from KNTV 13 ABC cited an upsurge in the number of cockroaches and similar insects across the Las Vegas Valley because of increased springtime moisture and seismic activity throughout the desert. Despite being a benefit to our ecosystem within the animal food chain, plant lifecycles, and for soil enrichment, cockroaches are hazardous when they infiltrate our homes. 

Las Vegas homeowners need to recognize the importance of promptly contacting a pest control professional when they detect evidence of cockroach infestation, and here is what they should know about doing precisely that.

Species Of Cockroaches In Southern Nevada 

Although more than 4,000 different species of cockroaches exist in the world, only a few types are known to invade homes in the Las Vegas region, including the American, German, Oriental, and Turkestan cockroaches. Common characteristics among all species include a flat oval-shaped body, six legs, and a pair of antennae. 

Appearance Of The Oriental Cockroach

The Oriental Cockroach (Blatta orientalis) has a dark brown or black color and typically grows to one-inch long. Both males and females have wings, but cannot fly and produce chemicals that cause a very unpleasant odor. You may also notice capsules of eggs dropped by females that are reddish or brown and roughly ¼ inch wide. 

What Attracts Oriental Cockroaches To Homes?  

Cockroaches often live in locations near the exterior of homes. Examples of common outdoor cockroach hiding spots include flower beds, garbage cans, and piles of wood. These pests are believed to be attracted to exterior lighting and may find their way indoors in search of food and temperature-controlled nesting locations.

Common Indoor Locations And Behavior

The Oriental cockroach is often referred to as the “water bug” because they are attracted to damp areas like puddles or leaking pipes. They are also found near other water sources including floor drains, toilets, and below sinks. As with most pests, they are commonly present near trash cans. Oriental cockroaches tend to gather in groups in low dark areas, and it’s rare for these pests to climb up walls or to enter upper cupboards or cabinets.

The Dangers Of Exposure To Oriental Cockroaches

Cockroaches pose a safety concern to people and pets because they trek through trash, sewers, and other unhealthy places. They are capable of spreading parasites and forms of harmful bacteria through their bodies and excrement. As they move through a home, they may contaminate surfaces, food, and utensils, which can cause problems such as salmonella and dysentery.

Oriental cockroaches shed and generate feces that emit airborne particles that may aggravate allergies and asthma. Small children, the elderly, and others with weakened immune systems are most vulnerable to illness. 

Best Practices To Deter And Limit Cockroach Invasions

A pest control professional is necessary for eliminating cockroach infestations. Some of the best practices for prevention are as follows: 

  • Using sealant or weatherstripping to block any exterior openings near doors, windows, and foundations.

  • Food should be placed in closed containers and dirty dishes should never be left out overnight.

  • Uneaten pet food should be placed in a container or disposed of.

  • Take out the trash daily.

  • Keep all floors and surfaces clean and free of any potential food sources. 

Treatment For Eliminating Cockroach Infestations 

A professional pest control expert may use a variety of methods to exterminate cockroaches. They may treat the interior using a form of bait, fogging products, or other chemical formulas. They may also apply some chemical products to the home’s exterior areas.
