German and Oriental Cockroaches
German Cockroach Habitat

German Cockroaches are primarily nocturnal and pests of warm, humid conditions.  Infest heated buildings, not normally outside or in underground heating ducts. Nymphs and adults cluster in groups in harbourages when inactive attracted by aggregation pheromone. Prefer narrow harbourages close to food and water source. Forage on a wide range of foods and need access to free water. can climb smooth surfaces.

 

German Cockroach Biology

Egg - nymph -adult

Eggs - in ooteca (case) each containing between 30-40 eggs. Egg case carried by cockroach female for 2-4 weeks until just before hatching.

Nymphs - 5-7 moults taking 2-6 months (average 3 months) to reach maturity. live and feed with adults.

Adults - small, active, yellowish brown, living average 6 months. Winged but do not normally fly.

 
German Cockroach Importance

The German Cockroach is known to carry and spread various human disease organisms. Its habit of walking over and feeding on putrefying waste materials, drinking at unsavoury water supplies, and then freely walking over food preparation areas, cutlery and crockery and human foods in search for further food enables it to spread many disease organisms. In addition to this obvious problem, there is the added factor of huan revultion at the thought of sight of large numbers of cockroaches appearing unexpectedly when darkened kitchen and other areas are illuminated suddenly at night. The rapid scurrying and running action  of cockroaches is upsetting, and the presence of so many insects may not even have been suspected by the owners or occupiers of the premises.

 

Control of German Cockroaches

This pest is easier to eradicate than the Oriental Cockroach  because of the prompt emergence  of nymphs from ootecae. However, to achieve complete eradication with permanent results - several treatments need to be carried out and spread over the actual egg-hatching period which may vary according to temperature. The thoroughness of treatments is all-important. The majority of products cleared for cockroach control are effective cockroach killers if they can be brought into contact with the insects. An integrated approach using a number of different formulations is essential against such a difficult pest. The treatment of harbourage voids using specialist application equipment is vital in any control program.

 

German Cockroach - Cost of Control and Quotes

Some pest control companies may advertise ''relatively low'' quotes for one or two cockroach treatments making it stand out as if they were quotes for cockroach infestation removal and in doing so rather confusing their potential customers. Be aware that one off or even two treatments are not enough to permanently succeed in removing a cockroach infestation.

Oriental Cockroach Habitat

The Oriental Cockroach is primarily nocturnal and a pest of warm environments but tolerant of colder conditions. Nymphs and adults cluster in groups in harbourages when inactive attracted by aggregation pheromone. Forage on wide range of foods but need access to free water. Found indoors in heated buildings, underground heating ducts and also in drains, refuse tips and outdoors near buildings. May even survive winter outside in protected environments but will not breed below 10 C. Climbs rough surfaces and may reach upper floors via vertical ducts, lifts. Does not tolerate extremely hot and dry conditions.

 
Oriental Cockroach Biology

Egg - nymph - adult

Eggs - in ooteca (case) about 5 per female, each containing average 16 eggs, laid at intervals. Deposited when fully formed in harbourage. Incubation time 6-12 weeks, longer if cool.

Nymphs - 7 -10 moults taking from 6 to 18 months to reach maturity. Live and feed with adults.

Adults - dark brown, robust, living up to 6 months. Partial wings or wing buds, incapable of flight.

 

Oriental Cockroach Importance

The Oriental Cockroach is known to carry some pathogenic bacteria, although direct evidence for disease transmition is scarse. The incidental damage caused by fouling and tainting foodstuffs and non-food materials. There is almost no tolerance within British society for the presence of cockroaches, and infestations in commercial restaurants and institutions are taken very seriously by Environmental Health Departments. Both, the Oriental and German Cockroach are considered Public Health Pests in UK.

 

Control of Oriental Cockroaches

There has been a tendency in the past to tolerate Oriental Cockroach infestations, particularly in old premises with poor structures. However, with modern materials and with pro-active strategies, eradication is possible in the great majority of situations.

Some pest control companies might advertise ''relatively low'' quotes for one or two cockroach treatments making it stand out as if they were quotes for cockroach infestation removal and in doing so rather confusing their potential customers.

Who is responsible and liable to pay costs for cockroach infestation removal on your premises; tenants, landlords?

If you are a tenant who has just moved in, then it is for your landlord to sort it out. It is your landlord's legal responsibility to ensure that the property is fit for human habitation at the time it is let. If you moved in and found the property has been infested with cockroaches, you would likely be justified in moving out. If the infestation occurred after you have been there for a while, then it depends on whose falt it is. However, an answer to the question may be difficult to establish particularly with cockroaches because even medium sized infestations may go un-noticed for a while before it gets discovered on an occasion. In addition, cockroach infestations may not necessarily be caused by the tenant(s) not keeping the flat or house in ''clean enough'' condition. Cockroaches may be introduced into residential properties in many different ways. They can migrate into a reasonably clean apartment from other infested dwellings in the same block of flats or from an adjacent property. Cockroaches may also be brought in with boxes of foods etc. As you can see it may in some cases be difficult to determine the fault.  All you can do as a tenant is to keep your rented house or flat as clean as possible and to check what you are bringing in so that your landlord may not hold you responsible if a cockroach infestation occurs. In the case you discover a cockroach infestation in your flat or house where you are the tenant it is advisable to first speak to your landlord about remedy.
