German Cockroaches-Signs Of An Infestation And How To Get Rid Of Them

German cockroaches are the most common type of household cockroaches. German cockroaches are experienced hitchhikers that typically first get into buildings by hiding in boxes, furniture and even potatoes and bags from the grocery store. Once German (or any species for that matter) cockroaches have infested your home, it is extremely difficult to get rid of them. If you notice one cockroach, there are probably thousands more hiding throughout your home. The following tips will help you recognize the signs of a cockroach infestation and how to get rid of them.

Signs of a German Cockroach Infestation

German cockroaches can survive and multiple in almost any type of environment, but they are commonly drawn to areas where there is food and dark, warm places, such as in the walls. Cockroaches are nocturnal, so they are often seen at night. But, if you have a severe infestation, they can be seen at any time of the day or night. Common signs of cockroaches include:

  • Trails or small piles of feces (looks similar to black pepper)-the best places to check is behind the refrigerator and stove, in cabinets, under sinks and in the pantry. Large amounts of feces in a visible location are usually a sign of a large infestation.
  • Brown egg casings-German cockroaches are aggressive breeders, but they produce oothecae instead of laying singular eggs. Oothecae are brown, oblong casings that house the eggs. When cockroach eggs hatch, they leave behind the brown casings. German cockroaches often produce oothecal with as many as 50 eggs inside.
  • Smelling cockroaches-cockroaches often produce a musty, pungent odor that continues to get worse the longer the infestation continues.

Getting Rid of a Cockroach Infestation

There are several types of treatment options to choose from, but the most effective way to get rid of an infestation of cockroaches is to have your home professionally exterminated. Some of the most common treatment options include:

  • Glue strips-these aren't typically effective for large infestations, but more for identifying heavy infested areas. The glue strip is placed in various areas, such as behind kitchen appliances, under sinks or in the cabinets. The strips are regularly monitored to determine where the most cockroaches are being caught. These areas will then need the most treatment.
  • Gel bait stations-bait stations work by attracting cockroaches to the station in order to feed on the poison. Once the poisoned cockroach travels back to a "home" location, it dies and is eaten by the other cockroaches, which ultimately passes the poison on to other roaches. Bait stations are somewhat effective, but they do not effectively get rid of all the cockroaches.
  • Boric acid powder-this is a substance commonly found in products like laundry detergent, but it can be effective in treating a cockroach infestation. However, boric acid is a chemical that can be toxic to children and pets if ingested. It will also lose its effectiveness over time, so it is not typically recommended as the sole method for getting rid of the infestation.
  • Professional pest control-hiring a pest control service is the most effective way to get rid of a cockroach infestation. A pest control company will use various methods to first get rid of the infestation and then continue with treatments to prevent future infestations.

When working with a pest control company for the treatment of German cockroaches, there are several prevention and treatment options to choose from. For example, choosing bimonthly pest control services means the technician will come to your residence for bimonthly pest control inspections and treatment if necessary. If you live in an area with changing seasons, monthly pest control may be the best option because of the continuous changing pest activities and behaviors.
