German cockroaches are well-known indoor cockroaches with a distribution that is world-wide. Adults are easily recognized by their light brown or tan coloration with two black horizontal stripes located on the pronotum immediately behind the head, and growing to a length of 13-16 mm. The much smaller young, or nymphs, are darker, almost black in color, also with the black stripes behind the head. While adult German cockroaches have wings, they rarely fly, preferring to run. Although capable of living outdoors in tropical environments, German cockroaches are most commonly found indoors, with a preference for the warmer and more humid areas of a structure. In homes, these insects will typically be found in kitchens and bathrooms, but can move to other areas of a home if food and moisture are available. In most cases, German cockroaches are introduced into a structure or residence when bags, boxes or cardboard containers are brought into the home. They may even be brought in with used appliances. In multiunit apartment buildings, German cockroaches can easily move between units, using the shared plumbing and pipes as a highway. German cockroaches are scavengers, capable of feeding on most any food source available, including toothpaste, soap and the bindings of books. These pests are known for their ability to capitalize on the availability of even the smallest amounts of food by feeding on crumbs missed during cleaning or feeding on the dirty dishes left in the sink overnight.
Cockroach Preparation Sheet
- Clean the home prior to the pest control visit, and maintain the home as neatly as possible for long-term results. This helps eliminate competing food sources for the insects. Additionally, when the home is clean, the roaches will be more attracted to the bait and not to food sources.
- Cover and store any open food. Remove foods, small appliances, and other small items from countertops.
- Store and/or cover baby toys, supplies and crib mattress.
- Mop/scrub kitchen and other hard floors and woodwork with detergent. Thoroughly vacuum carpeted floors.
- Vacuum up any visible roaches and eggs just before the service visit, using the crevice tool to get into cracks. After vacuuming, take the vacuum cleaner outside, remove the vacuum bag or empty the dirt cup, seal it in a trash bag and discard in the trash. Take a damp cloth and wipe down the entire vacuum cleaner. Continue to vacuum or otherwise kill any roaches that are seen.
- Always keep garbage in closed containers and take out the garbage every night.
- Remove items from the top of the refrigerator, stove, and any other such movable appliances. Prior to service, move these appliances away from the wall, and clean behind and beneath them. If the stove has a removable bottom drawer that opens to the floor, it is not necessary to move the entire stove.
- Be sure that the pest control operator has free and full access to anywhere that cockroaches have been seen.
- Discard all excess paper products, and any other unused piles or trash, as these are harborage areas for roaches.
- Homeowners should repair any water leaks immediately upon detection; apartment residents should report the leak to maintenance immediately upon detection.
- If anyone in the home has allergy problems, is pregnant, or is under the age of one, the Technician should be informed prior to service and precautions taken. All people and pets should stay out of the area being serviced for the minimum 4 hour length of time specified by Health Canada
- After service, keep sanitation to as high a level as possible to allow all products to work as swiftly as possible. Do not touch cockroach gel or allow children or pets to get near.
