Cockroaches

Cockroaches

Well these insects hate the light; very rarely will you see one properly when you turn on the light. Normally it’s just a movement in the corner of your eye.  The Oriental cockroach is the slower and less active of the 2 most common Cockroaches found in the UK. Some say it is the most common but I expect that depends where you live and who you ask. Personally, I have no idea. What I do know is that they are about 1 to 1.5 inches long (between 2.5cm and 4cm) and are a brown/black colour.  There is a difference between a male and female that is clearly recognisable but I won’t bore you with it, suffice to say it has something to do with ‘wing length’.

The Cockroach live in large colonies; often spread throughout a property, if left unchecked. The female can lay in excess of 160 eggs in her lifetime. They tend to hide in dark spaces like under or behind units, behind picture frames or in the back of a fridge. We are all at risk of getting these as there are various ways for them to enter the house but with the changes in the way we live they are not as rife as they were years ago when we used to burn coke.

Apart from seeing them in your peripheral vision you could see tiny (2mm) droppings or even a husk as they shed as they grow.

The German Cockroach is the other common species found in the UK. Again some argue it is the most common. “I still have no idea.”

The differences between this type and the Oriental Cockroach are:

  • These are light brown.
  • Size, these are a lot smaller. 5/8ths inch (12/15mm)
  • They prefer dark DAMP spaces or are close to a water source.
  • They are more protective of their eggs. (protecting them until they hatch and often helping them to do so)
  • These CAN fly but prefer not to.
  • They can walk on the ceiling…………
  • They are quicker to build up a resistance to insecticides.

The German cockroach will be transported from place to place in the same way as the Oriental, they hitch a lift in bags or packaging, being that much smaller they can get into smaller openings.  The females tend to be found in groups, maybe another protection strategy and although you would use the same method to see if you had them the German Cockroach may venture out in daylight if there is very little activity.

The cockroach is difficult to get rid of.

SO………….. Can they really survive a nuclear explosion?
