Hi everyone.
Looking for any help anyone can offer.
We have a 50ft long,10ft tall beech hedge running all the way along one side of our garden, it's a lovely old hedge and is 100 odd years old I'd say, so very well established.
It has become totally, and I mean totally infested with whitefly. They are spreading onto the flower beds, raised beds and plants also the tomatoes chillis etc.. The air is also thick with them so even going into the garden is pretty unpleasant.
What, if anything can I do?
Many thanks.
Eugene.

I'm making an assumption that systemic insecticides, like acephate or imidacloprid, are "off the table", either because of bans or undesirability with regard to effects on bees, etc.
Try Googling "whitefly IPM control". That will lead you to many choices in the field of Integrated Pest Management. You can narrow that search to specifically find IPM methods applicable in the UK.

Can you give them a good hard spraying with a hosepipe, that'll kill a lot of them. If the weather would warm up, you'd probably get a swarm of ladybird bugs that would clear them in no time.
Other than that encourage birds into the garden, hanging bird feeders in the trees, so they find the whitefly..

I would try diluted Neem oil with a hint of Lux flakes. Sorts out my whitefly problem.
Cheers, Tony.
