Portuguese millipede (Ommatoiulus moreleti)
Since the autumn break the Portuguese millipedes have been invading our house each night.
It didn't take long to realise they were heading to light and higher ground and so I decided to use this characteristic to trap them in their thousands.
The use of drop traps and garden lights has produced a bucketful of the pests in two nights, so I decided to publish the system on our web site to help others seeking an environmentally friendly way to reduce their numbers.
The following images show how you can set up traps and prevent the breeding of a new generation from the trapped numbers.
