Watch Out For Pine Caterpillars!

Watch Out For Pine Caterpillars!

PROCESSIONARY PINE CATERPILLARS

These Caterpillars (Thaumetopoea Pityocampa) may look cute and furry, but they are very DANGEROUS to children and especially dogs.  DO NOT TOUCH THEM.

These are one of the most dangerous natural enemies to dogs and can be found all over Spain. Some have even made their way to parts of the UK:

The processionary pine caterpillar as the name suggests makes its home in a certain type of pine tree., damaging the trees over a period of time.  These trees are very popular here in Spain and are a protected species so even if you have pine trees in the garden you cannot cut them down.

There is only one generation per year and most of the time the caterpillars are not seen and therefore not a threat.

Why are they so dangerous?

Long hairs give out poison that when touched irritates the skin. Allergic reactions are not unknown and if ingested the consequences can be dire, especially to dogs and young children.

The picture below is what the rash looks like, take some antihistamine tablets and see a doctor immediately

This is the damage it can cause your dog, many dogs have to have their tongues cut. If your dog is having any breathing difficulties take it to a vet IMMEDIATELY

What do they look like – 

The Nests – Nests: Normally from about January (although in this area they were visible from early December in 2015)  the caterpillars build distinctive, tent-like nests of white, silken, webbing up to the size of a football in the branches and foliage of pine trees, and there can be several nests in a single tree. The caterpillars spend the days in these nests, and leave them at night to forage on the tree’s needles.

The Catepillars – The easiest stage of the lifecycle to recognise is the caterpillar, which is hairy and coloured orange-brown with blue bands. Like the caterpillars move about in nose-to-tail in processions, hence the name, and this is when they are at their most deadliest.

Moths: Adult moths have cream forewings with brown markings, and white hindwings, but to an untrained observer they are difficult to distinguish from other species of moth. They are flying about May to July, and individuals live for only about a day, during which time they must find a mate and lay their eggs in the foliage of a pine or other host tree.  These moths are not dangerous.

In the affected areas take some simple precautions to help minimise the health risks to you and your pets:

DO NOT:

    • touch or approach nests or caterpillars
    • let children touch or approach nests or caterpillars
    • do not let your dogs sniff the caterpillars as they will inhale the poison.
    • hit the caterpillars with a stick or stamp on them because this will just send their spines into the air in a kind of toxic dust cloud that can be inhaled

DO:

    • teach children not to touch or approach the nests or caterpillars
    • train or restrain pets from touching or approaching them;
    • see a farmacia for relief from skin or eye irritations after possible contact
    • see a doctor if you think you or someone you care for has had a serious allergic reaction ie rash or breathing difficulties.
    • see a vet if you think your pet has been affected.  DO this ASAP as you may not have long to save your pet from serious damage or even death.
    • If you have any in your garden you can call Seprona on 062 and ask them to come round and deal with them
    • If you simply have to walk in the woods around this time the official advice is to carry some antihistamine tablets with you.
    • Keep your dogs on a lead during this time of year.

Destroying the nests – be cautious.

Purchase a hormone trap which, very basically, emits a hormone that makes all the male caterpillars smell like females. The resulting orgy of confusion means there won’t be many babies produced and the colony will die out.

A popular method of control is to destroy the nests during winter as soon as they become visible in the trees, (i.e. before January) by cutting them out of the trees and burning them. But take proper precautions when doing this and consult an expert. One supposedly recommended method is to spray the caterpillars nest with hairspray, Which helps to trap the hairs, wrap it in a plastic bag and torch it.

Nasty horrible things, and lots around early this year, especially in the sierra-helada/gelada-natural-park area, so many people are still allowing their dogs off the leads, which seems very irresponsible https://www.benidormseriously.com/sierra-heladagelada-natural-park/
