Cockroaches are considered a serious urban pest as they're known to spread disease, contaminate our food and cause allergies and/or asthma, particularly in populations of the very young and the elderly. Generally, they live in filth and as they travel looking for food and water they transfer germs from trash and/or sewage into our living spaces. According to the University of California Agriculture and Natural Resources (UCANR), cockroaches are known to cause infection by carrying bacteria such as Staphylococcus spp. & Streptococcus spp., hepatitis virus, coliform bacteria, as well as causing food poisoning by carrying Salmonella spp. and Shigella spp. bacteria. Historically they have also been linked to typhoid, dysentery and cholera.
For successful management of these notorious invaders it is imperative to correctly identify which species you're dealing with. The two most common species found in American urban areas are the American cockroach and the German cockroach.
The American - Periplaneta americana
Commonly known as the water bug or palmetto bug, they typically reside outdoors near moist, humid environments such as drains, sewers and trash receptacles.
- They are the largest domestic cockroach species
- Reddish brown in appearance
- Moderate flyers
- Females carry egg case (ootheca) for about a week before dropping it and continuing her search for food and shelter. It incubates for about 2 months before hatching and continuing the life cycle.
- Ootheca carries approximately 12 young.
- Female cockroaches can produce up to 800 cockroaches in 1 year.
The German - Blattella germanica
Notorious world-wide indoor pests hiding in cracks and crevices particularly in food prep/storage areas. Their most notable characteristic is their rapid reproduction rate - a single female and her offspring can produce up to 30,000 cockroaches in one year.
- Light brown or tan coloration with 2 dark horizontal stripes down their pronotum (top-side)
- Much smaller than American cockroaches
- Female carries egg case (ootheca) with her until a day or two before it hatches
- Ootheca is tan in color and carries approximately 35 young.
- Droppings look somewhat like black pepper and are smattered around infested areas such as walls, under refrigerators, in cabinets, etc.
- Have wings, but rarely fly
If you suspect or have sighted bugs, call ExCimex or a Pest Management Professional (PMP) immediately for identification and treatment options. Knowing the species, you will be better able to determine where the source of infestation is and where to place traps, baits, or chemicals. Treatment is not a one-time deal. Repeated steps and ongoing monitoring is necessary.
First, locate areas of cockroach activity, then identify the causes of infestation, and look for entryways for bugs to get into your home. The more hiding places you locate and manage, the more successful your control program will be. The key to managing cockroaches is exclusion and sanitation.
- Removing all food and unnecessary water sources
- Sealing cracks and crevices
- Vacuuming and removing harborage sites like cardboard, paper products, plastic bags and trash.
- Chemical application in select target areas. (Example: sprays, gel bait, granular bait.)
- MONITORING - using sticky traps, pheromone traps, sanitizing and visual examination for weeks following a program.
The most important component of managing a cockroach infestation is to change the conditions that promoted infestation in the first place. Cockroaches, along with all organisms, are driven by survival and they are likely to reinvade as long as they find a suitable habitat (i.e, availability of food, water, and shelter).
All in all, don't let cockroaches get you down. They are common and they are everywhere, but there are ways to control them! Do the research and call for help.

Trash (garbage and recycle) chutes are an integral part of multiple-occupancy, multiple story buildings. They provide a convenient means of transporting refuse to a central collection point (Trash Collection Room). The chutes are actually very sophisticated systems, in that they are designed to move trash and garbage, but also provide a fire protection barrier. If these systems become clogged or impacted with residue (grease or organic materials) they become a DANGEROUS conduit or chimney for fire. But most importantly they act as a multiple floor elevator system for urban pests.
COCKROACHES are aggressive and persistent pests, and will take up residence wherever there is a food source.
The most common of the urban pests are cockroaches and the most commonly found in the cockroach family is the GERMAN COCKROACH. If left unchecked, one female GERMAN COCKROACH (typically found indoors) can produce up to 30,000 offspring in one year.
Also very commonly found is the AMERICAN COCKROACH, usually an outside dweller, will seek dark, moist areas for harborage and then travel to nearby sources to feed.
Cockroaches tend to gather in the Trash Collection Rooms; in and around the dumpsters and wall voids, and use the Trash Chutes as a means of moving up into the actual living areas.
PROPER TRASH CHUTE CLEANING AND MAINTENANCE is highly specialized, and requires close coordination between the building management and maintenance teams, and the residents. If properly planned, with the required materials pre-staged, the process can be smooth and efficient.
ExCimex will inspect and develop a Trash Chute cleaning and maintenance plan specifically for each unique application. We work closely with management, as well as local authorities to PREVENT any residue from entering the storm drain system. Our process uses only GREEN enzyme products which biologically break down the residue. We also utilize a specially formulated de-odorizing product, and then introduce a low volume pesticide barrier. We work alongside maintenance personnel, and provide hands-on training.
