Box Tree Caterpillar Tops The Vine Weevil Again!
The RHS today released the top 10 garden pests, as searched for by their members throughout 2019. The Box Tree Caterpillar remained in the number one spot after another year of expansion here in the U.K, a trend which looks set to continue. These figures are backed up by data at Dragonfli with our Box Tree Caterpillar Moth Pheromone Trap sales increasing year on year.
The Alder Leaf Beetle has made an appearance on the list for only the second time, a metallic green beetle which feeds on Alder leaves. It has been speculated that milder conditions in the UK have encouraged the re-emergence of this species, which will come as a concern for gardeners.
We have taken this opportunity to provide you with some quick links to our natural products and solutions for the control of each pest. As always if you need any further help or advice you can always Ask Our Expert.

Do you do a pheromone trap for apple ermine moth?
Have you any suggestions for combating them?

Hi Bryony,
Many thanks for getting in touch.
There are very few natural predators available to help combat this particular pest unfortunately. The only solution I can advise is to pull off as much of any developed webbing as possible and spray our Caterpillar Killer Nematodes directly onto the caterpillars. They will be able to kill them on making the required contact.
I hope this helps but if you need any further information please do not hesitate to contact us again.
Kind regards,
Julian Ives [Director, Dragonfli]
