Pile of logs

Beetles found in a log basket

13 March 2019

With more people having wood burning fires installed we have in recent months seen an increase in people finding unexpected visitors appearing from the log basket! Here we have a photograph of a Forest Longhorn Beetle that found his way in to a property via the log basket – much to the surprise of the property owner!

Forest Longhorn Beetle found in logs

Generally, the type of beetles coming out of stored wood at this time of year will have been in the timber since it was alive, therefore the beetles are not interested in the now dead wood and emerge.

As most firewood tends to be hardwood the range of possible beetle species is limited in this case we were able to identify the Forest Long Horn variety. This type of beetle cannot re-infest dry timber without bark present and is not a risk to the house timbers.


Tips for keeping firewood at home

To limit the chances of beetles taking up residence in your firewood there are some simple rules for you to follow.

Storing and using firewood

– To limit woodworm infestations in firewood, stack the wood undercover with the logs off the ground so that air readily flows through the pile. It is not recommended to put a sheet over the logs as that will decrease the airflow over the firewood and will potentially leave the firewood damp. Well-dried wood will not prove to be as welcoming to beetles as damp wood. The drying process may also kill many developing larvae already present in the wood. To speed up the drying process of the logs make sure they are cut into small lengths of approx 25cm and not stacked over 1m in height as the pile will become unstable. it is important to be as tidy as possible when stacking the logs as a tight stack will ensure that only the top layer will potentially get damp should it rain.

– Piles of wood should not be stored up against buildings. It is suggested that firewood is stored at least 3 feet (if not more) away from a structure.

– Keep firewood away from trees – This helps prevent any beetles, such as the Forest Longhorn Beetle, leaving the firewood pile and causing damage to living trees. Another reason for not storing logs under trees is that water can drip down and make the logs damp. It is also best to avoid low lying areas if at all possible as they can be prone to dew, mist or fog.

– Never stack firewood inside – This helps to limit the chances of beetles and other pests taking up residence inside!

– Try to use only local firewood – any wood that is not from a known local source should ideally be burned first to kill off any unwanted pests living within the wood.

– It is always best practice to operate a first in first out a policy with firewood. This will help to keep unwanted pests to a minimum as this limits the available time for an infestation to build up.

– Before bringing the firewood inside always give the logs the once over for any visible signs of beetles and pests. Shaking the logs and banging them together will help remove any that are on the surface or starting to exit the wood.
