Deadly caterpillar arrives in the UK
02 August 2010

Experts have called on the Government to help wipe out a moth that can trigger potentially lethal asthma attacks. 

The Oak Processionary Moth arrived in the UK in 2006 on a batch of imported oak trees. The species has since gained a foothold in the South East and is now spreading further.

Tony Kirkham, the head of Kew Gardens arboretum told the magazine Horticulture Week: 'We will lose control this year - within five years it will affect everyone within the M25.' The caterpillar is covered with approximately 62,000 hairs that it can eject at will, sending dangerous bristles through the air.

Dr Elaine Vickers, Research Relations Manager at Asthma UK, says: ‘The caterpillars of the Oak Processionary Moth could pose a significant threat to people with asthma, as the toxin-containing bristles of the caterpillars can become airborne and, because they can irritate the airways and cause allergic reactions, they have the potential to trigger severe asthma attacks.


‘The caterpillars can be found in urban areas as well as parks and the edges of forests, and the public should report any suspected sightings to the Forestry Commission. People with asthma should also always remember to carry a reliever inhaler with them in case of unexpected asthma attacks.



‘In recent years the Oak Processionary Moth has extended its reach northwards through Europe, most likely as a result of climate change.
 


‘The health impacts of climate change are likely to be enormous but have received little attention, so it's vital that more research is carried out to understand its potential effects on respiratory health. The warming European climate, reported increases in the length and severity of pollen seasons and increased urban air pollution could cause huge problems for many people with asthma in the years to come, and could potentially also cause a rise in asthma prevalence.’
