The number of cockroach infestations reported in Ireland last year rose by nearly 70% according to figures released today. 

This is the twelfth year in a row in which pest control company Rentokil has seen a rise in the number of complaints received relating to the insects in Ireland. 

The company said the growing popularity of imported food, coupled with an increase in foreign travel and overall warmer weather conditions have contributed to the rise of the hardy creatures on these shores.

Dublin bore the brunt of the reported infestations with the capital accounting for two-thirds of the reports received in Ireland. 

Cockroaches can carry a number of worrying health risks including salmonella, typhoid and gastroenteritis - while their droppings can cause both asthma and eczema. 

According to Rentokil, many restaurant staff do not recognise when incoming stock contains a cockroach infestation. 

The company has warned customers to be vigilant against the pest when dining. 

Dr Colm Moore, area technical manager at Rentokil said it is "vital that those working in the hospitality sector look out for the signs of the public health pests.”

“Cockroaches pose a clear risk to human health and we all have a responsibility to be vigilant to signs of an infestation,” he said. 

Dr Moore said the most common signs of a cockroach infestation include a “lingering and unpleasant odour,” shed skins - usually close to where the insects are sheltering - and cylindrical 2mm droppings.
