DIY – Cockroaches – Combat these invertebrates with our 9 top tips

Members of the cockroach family can be found in various habits including forests, fields, moorlands but the area we are going to concentrate on is ‘human habitat’.

With an array of species I would also like to narrow our advice to the two most commonly found in the UK – Oriental and German.

Regardless of the species understanding which species you actually have and the numbers you are dealing first is vitally important. Visual inspections and traps are a good way to ascertain this information

Oriental

Length – 17mm – 30mm

Female carries around 5 purses of 16 eggs each. These get left in various locations and hatch several weeks later

Known to carry bacteria that poses a risk to public health

5 Top tips for the – Oriental

  1. Remove all available food sources. Check under kitchen until, remove grease around ovens and but edible food stuffs in sealed containers
  2. Repair any broken tiles, flooring, worktops etc (seal with silicon, mastic or equivalent)
  3. Clean, clean and clean all areas of concern
  4. Repeat number 1, 2 and 3. Oriental cockroaches can take time and repeated treatments are almost always appopriate

 

German

Length – 12mm – 15mm

Female carries eggs (between 30-40)  for between 2-4 weeks before they hatch

Can spread very quickly in heated buildings

Like-for-like these are often easier to control than their oriental cousins

4 Top tips for the – German

  1. Remove all available food sources. Check under kitchen until, remove grease around ovens and but edible food stuffs in sealed containers. Venture higher up with the German as they are great climbers. So look at food on top of cupboards/fridges etc
  2. Use a bait (edible that reacts in the stomach). By far the best way of controlling a population, especially if applied in/around their harbourage
  3. Wet spray insecticide can be used in adjoining rooms
  4. Clean/inspect areas throughout treatment. Monitoring traps can be used but visual checks will show whats actually going on

If in doubt and especially if you feel public health is at risk – contact your local pest controller (check the NPTA for an accredited member in your area)

Hope this helps,
