Horse Chestnut Leaf Miner traps

The Horse Chestnut Leaf Miner trap contains a pheromone lure that attracts male Horse Chestnut Leaf Miner adults in huge numbers.

Once caught in the trap they cannot escape and perish. This 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.

Each Miner Trap is supplied with 3 lures - enough to last the whole season. Replacement lures are also available. 

Key points: 

• Horse Chestnut Leaf Miner (Cameraria ohridella) is becoming an increasing problem in the UK

• Horse Chestnut Leaf Miner drills into the tree leaves, causing them to dry up and turn brown

• Damage leads to sickly appearance and early leaf fall, reduced seed vigour and poor germination

• Reduction of conkers

• Hang one trap per tree from April until the end of August

• After 6 weeks remove the trap, empty its content and add a new lure
