The German cockroach is one of the most common roaches found in apartment houses, restaurants, and hotels. German cockroaches (eggs included), are "brought in", usually on man's belongings, luggage, boxes or packages. All it takes, is bringing in one egg capsule, six months later you have an infestation.

 

German Roach Control & Treatments

 

German Roaches & Sanitation

When beginning your German roach control program, sanitation is one of the first things to consider. German roaches only need a small amount of food to sustain them.

  • Remove indoor trash or keep them emptied.
  • Keep trash dumpsters clean.
  • Make sure food is not left in sink stainers and frequently run the garbage disposal.
  • Keep dishes clean, no residue of food remaining.
  • All kitchen appliances (microwaves, toasters, ovens, refrigerators and stoves) should be maintained in a clean condition so that it is food free and grease free.
  • All pet food needs to be picked up.
  • No food left out.
  • Sweeping or vacuuming of any food particles or crumbs.
  • Clean any crumbs or food particles in your kitchen cabinets.

Inspection : Look for Evidence

When inspecting for German cockroaches, thoroughness is very important. It is important to place the insecticides as close to their runways and harborages as possible. Their excrement looks like black pepper.

A flashlight would be a handy tool to check the following places.

  • Cracks and Crevices
  • Behind and under refrigerators
  • Behind and under stoves
  • Behind and under microwavesa and toasters
  • Under tops of tables
  • Behind and under sinks
  • Cabinets-corners and cracks and crevices
  • Motors of refrigerators and soft drink dispensing machines
  • Switchboxes and electical outlets
  • Under and behind cafeteria counters and soda fountains
  • Cash registers
  • Telephones
  • Vegetable bins
  • Recycling bins
  • Meat counters and check-out stands
  • Meat cutting blocks
  • Anywhere else conditions are favorable.
  • Every situation may be different, inspect all places with favorable conditions

 

 

Using Baits, Insect Growth Regulators (IGR'S), Dusts and Roach Traps

We recommend using gel baits, dust baits, roach bait stations, insect growth regulators(IGRS), dusts and roach pheromone traps for residential and commercial areas. Very often high levels of control can be achieved by baits alone for the typical homeowner. Several very effective bait products are on the market today. However, like any chemical control, resistance to the ingredients in baits can occur. The products we recommend have not had a resistant problem. For locations with a continued problem, it is recommended to rotate baits. Commercial kitchens and restaurants however may be an exception of using just roach baits.

For German Roach control in restaurants we recommend the use of insecticides, aerosols, dusts, and insect growth regulators instead of baits. There is too much competing food sources for effective control of german roaches in restaurants with bait.

Roach Bait Stations

These bait stations do not work as quickly as the roach bait gels, but they do not dry out.

It would be perfect in maintenance situations.

 

 

Where Do I Place These Baits ?

Typical harbor aging areas for German Roaches and places for treatment of Roach Bait :

German roaches will exist under favorable conditions of food, water or warmth.

Before treating any area, it is best to first take a flashlight and checkareas for harborage sites. Look for their excrement droppings(looks like black pepper).

.

Suggested Bait Placements

Cracks and crevice placement, as opposed to placement on exposed surfaces is preferred because roaches do not travel far from their harborage. These precise placements result in better control because you have placed it in areas that the roaches spend most of their time.

  • Behind kitchen cabinets and counter tops.
  • Behind anything hanging on the wall, such as pictures, clocks, posters, etc.
  • Behind, next to, and under the stove.
  • In the corners up under the sink and other cabinets.
  • In stored paper bags and boxes.
  • Around pipes, cords, and cables that come out of the wall.
  • Behind and under bathroom fixtures.
  • Behind the medicine cabinet and vanity.
  • In any cracks or crevices around shelves or wood trim.

Roaches are cannibalistic and will eat other dead or dying roaches.
The roaches are not social insects like ants and termites, they do not carry the bait back to feed the young. The bait is passed through by excrement or eating the dead roaches.


It is important to re-bait in the areas where the the roaches are taking the bait. Paying attention to this will speed up the treatment.

 


What are Insect Growth Regulators?

Using insect growth regulators like Gentrol IGR'S and Pivot 10 IGR break the roach growth cycle. Gentrol IGR'S attacks the male nymph roach(mutating reproductive abilities) and causes the pregnant female to consume the bait when she would normally not want to consume food during part of her pregnancy.

How do I use insecticide dusts for German roach control ?


Dust should supplement any insecticide of bait control program for German roach control.

Sometimes, bait alone will not be sufficient for roach control. Restaurants will need a good dusting/liquid insecticide program because baiting will not work.

Those that live in apartments might benefit from dusing behind the plumbing area under their sinks and electrical outlets.

When you apply them to recessed and dry areas, they give you long lasting results. Typical areas to dust would be electrical outlets, so a hand duster with a plastic tip would be needed.

Do not place these dusts in the exact same location of any roach baits, as it would contaminate the baits.

What are the purpose of Cockroach Traps?

These not only trap roaches, but is an excellent monitoring tool. Cockroach infestations can be monitored with these pheromone traps. These low profile traps can be placed under cabinets adn kitchen appliances. They can be placed out of view, but close to harborages. It is recommended that traps ve placed flush against surfaces. As those placed 3/4 inch from walls cach about half as many cockroaches as those placed flush against them.

Other Aerosols and "Bombs" to Kill Cockroaches


Use D-Force HPX Aerosol if you need a slightly quicker start before killing the entire roach population with your roach baits.
However the recommeded roach baits are so effective,many find they don't need to use such an aerosol.
When using this residual insecticide (D-Force HPX Aerosol), don't place the bait out yet, because it would contaminate it.....wait about 10 days.
D-Force contains Deltamethrin.

We also carry other insecticides, baits, and dust not listed here

 

Aerosol "bombs" such astotal release bombs Evercide Bombs so commonly referred to are actually total release aerosol cans.
They are very popular because they are perhaps the easiest way to kill exposed roaches without much effort, just push the button and leave the premises for a couple of hours.


Unfortunately, "bombs" do not contact many roaches that are well hidden and they have no residual killing power.

 

 

 

German Roach Control in Restaurants

Many times, german roach control in restaurants require insecticides as opposed to baiting. Using baits in German roach control requires that their is no competing food sources. In restaurants, it is almost impossible to eliminate all competing food sources.

The top recommendation for restaurants

In restaurants, you may have to still spray with a residual insecticide such as :
orthene pco pellets Orthene PCO instead of baits.
We encourage you to call us for recommendations, in that we have had a long history of helping restaurants solve their problem, but needs to be handled on a individual basis. Use Pivot IGR mixed with Orthene PCO insecticide to stop the reproduction.

Another product that is recommended for restaurants is:
Eaton's Boric Acid Powder.
A mop rinse insecticide that leaves an odorless, invisible residue which cockroaches cannot detect.


 

 

 

German Cockroach Appearance

Adult German roaches range in size from 1/2 inch- 5/8 inch long. They are light to medium brown. They have 2 dark distinctive stripes behind the head. The young German roaches (nymphs) are smaller than adults and are wingless. They have a light stripe on their backs and are darker in color.

German Cockroach Diet



These roaches will eat a broad range of foods and prefer to stay close to food and water sources.

 

Habits and Biology of German Cockroaches

Females produce one egg capsule every 3-4 weeks. Each capsule contains 25-45 eggs, the largest capsule of all roach species that would infest a building. The female will carry the egg capsule with her until it is ready to hatch, making it less hazardous for the nymph to survive.

It also has the shortest period to develop from hatching until sexual maturity. The populations of German cockroaches will build up faster than other species The young (nymphs) will be able to breed in as little as 36 days. A combination of these traits produces what entomologists call a "high reproductive potential."

German cockroach nymphs are smaller than most other cockroaches; thus, they are able to conceal themselves in many places and remain protected.

Adult German roaches can live up to one year. These roaches are mostly active at night .

If German roaches are seen active during the day, it most likely is due to overcrowding in their hiding places or a shortage of food and water supply. Cracks and crevices are their harborage areas; they spend about 75% of their time in such harborages. First instar nymphs require a crack of about 1/32" whereas, adults require "in width.

German roach Infestations are usually are generally found in kitchens and bathrooms. If the population is large enough, they will spill over to other rooms.

The German cockroach can move well within a building. They also can travel from a neighboring apartment or location to another and can pass through small openings like light switch plates.

Many times they are brought in with grocery items, grocery bags, cartons, handbags, and luggage.

An inspection is important to find all potential harborages and a determination if it had been brought in with certain items.

If insecticides have been used in a building, there is a possibility that the German cockroach simply scattered to another area. These harborages need to be located and treated. It may not be possible to eliminate all the German cockroaches in a building completely if a consistent supply of cockroaches is carried into the premises via packages or food shipments.
