Horse Chestnut Leaf Miner Pheromone Trap


What Are Horse Chestnut Leaf Miners?

The Horse Chestnut Leaf Miner Moth (Cameraria ohridella) arrived in southern regions of the United Kingdom during 2002-2003 and has steadily spread north. The moth reproduces in large numbers, with 200-300 eggs typically laid on each leaf from May to August. Damage is caused by the larvae of the moths, as they mine into the leaves of the trees. The moths often merge which gives the Horse Chestnut leaves a white and blotched appearance. The leaves will then dry out, browning, before they fall off the tree prematurely. This causes the tree to have an autumnal appearance as early as August. The long terms effects on the Horse Chestnut Tree are still being examined, but the trees do appear weakened and therefore more vulnerable to attack from pathogens and diseases.

How Does This Trap Help Combat Horse Chestnut Leaf Miners?

The Dragonfli Horse Chestnut Leaf Miner Pheromone Trap uses a species specific pheromone lure to catch and trap male Horse Chestnut Leaf Miner Moths. The moths will detect the pheromone and fly into the trap expecting a female Horse Chestnut Leaf Miner Moth to be present. Moth mating and egg laying will be reduced as a result, and future generations of larvae will be prevented from developing. Moth populations can also be monitored through this trap which will help provide you with an early warning as to their activity. The trap is capable of catching hundreds of Horse Chestnut Leaf Miner Moths and significantly reducing damage to leaves and trees.

Catch Higher Numbers Of Pests With This Larger Horse Chestnut Leaf Miner Trap

The Large Horse Chestnut Leaf Miner Trap has been designed specifically to attract and catch higher numbers of the Horse Chestnut Leaf Miner Moth. It can be purchased as an alternative to, or used in combination with, our standard sized Horse Chestnut Leaf Miner Trap. This larger trap should be used in large or mature Horse Chestnut Trees which have a lot of leaf canopy

How Do I Set Up The Trap?

Each trap is supplied with three pheromone lures to last an entire Horse Chestnut Leaf Miner season. These are the same lures used for our standard sized Horse Chestnut Leaf Miner Traps. Simply remove the lure from the foil sachet and place it in the cage at the top of the trap.

The Large Horse Chestnut Leaf Miner Trap supplied by Dragonfli is a large funnel trap which is entirely glue free. It also only has holes big enough for moths which prevents the capture of larger insects and small birds, which might fly into a conventional trap by accident. The funnel trap should be filled with water so that when the Horse Chestnut Leaf Miner Moth enters the trap it will fall into the water and drown. The trap utilises an opaque bowl allowing for inspection of successful catches.

Hang the traps from the trees you wish to treat for infestation.

Full application instructions are provided on delivery.

How Many Traps Do I Need And What Distance Will It Cover?

Hang one trap per large tree from April.

When Will I Need To Replace My Trap?

The trap can be used for years and replacement lures can be purchased separately here.

Each trap comes with three pheromone lures, each of which last up to 6 weeks, giving the trap an initial 18-week protection. The pheromone lures should be replaced 2 to 3 times between April and August to catch as many hatching generations as possible.

A replacement pack of small parts for this trap can be found here.

The camera hasn't lied

We have taken photos to demonstrate the difference made by the pheromone traps, to prove to the sceptics that over time these traps are effective in controlling the leaf miner moth, but it isn't an instant cure. It takes time and persistent consistent use of the recommended methods . We are into year two. A friend says it ultimately takes several years but worth it.

As the traps were being put up in the trees the moths immediately came streaming down the trunk towards them. They are filling up fast so 🤞 the trees will keep their leaves into the autumn

Very effective

Bought one fairly late in the season but it trapped tons of the little blighters. Looking forward to using it in the spring when the moths become active again.
Had to be careful emptying the water as often there were so many in there the ones on top remained alive. So a quick sluice or emptying away from the tree was needed.
