Horse Chestnut Leaf Miner Trap

Horse Chestnut Leaf Miner Control

The Horse Chestnut Leaf Miner trap is used to store a powerful pheromone lure that attracts male Horse Chestnut Leaf Miner adults in huge numbers where they are caught and perish. This system reduces mating leading to reduced egg laying.

The traps do not totally stop damage or completely control Horse Chestnut Leaf Miner, but continued use of the trap over several seasons reduces the damage caused and can help to delay the early leaf fall caused by this pest.

Horse Chestnut Leaf Miner Damage

Horse Chestnut Leaf Miner (Cameraria ohridella) damage on Horse Chestnut trees is becoming a common problem in Southern England and is spreading into other areas. Distribution Maps.

The adult moths lay hundreds of eggs, which develop into caterpillars that drill into the Horse Chestnut tree leaves, causing them to dry up and turn brown. This gives the tree a very sickly appearance and leads to early leaf fall, reduced seed vigour and poor germination. The damage is not fatal to the tree but one effect is the reduction in the size of the conkers from infested trees.

More information about the spread and damage of Horse Chestnut Leaf Miners can be found on the Forestry Commissions website.

How to use

Before placing the trap in the Horse Chestnut tree; add the Cameraria ohridella pheromone lure into the top of the castellation trap. A small amount of water with detergent can also be added to the trap to ensure adults to not escape.

Hang one trap per tree by April. Each pheromone lure will last about 6 weeks. After 6 weeks remove the trap and empty its contents. Add a fresh lure and put back into the tree. This should be repeated at least 3 times from April to the end of August. This will ensure that new generations of Horse Chestnut Leaf Miners are caught.

In the Autumn the traps can be removed, cleaned and stored for use the following season. It is recommended to use the traps each year to reduce numbers and damage.

Leaf litter should be removed after leaf fall and burnt. This will significantly reduce the amount of overwintering Horse Chestnut leaf miner pupae.

Packs of 3 Pheromone Lures are supplied seperately.

What Our Customers Say

Our Horse Chestnut tree has been heavily infected with Horse Chestnut Leaf Miners over the last two years.
I came across this Trap and Lure system and thought it was worth trying. The results have been amazing, when I emptied the trap to replace the lure the number of leaf miners in the trap were staggering, literally in the thousands.
I am very happy with the results so far.
