BugClear Ultra Vine Weevil Killer 480ml (12)

I think this is because the manufacturer dont tell you the correct time to use the product, the product say use it when the weevil grubs are active which is why I think you get poor results, as you need to get the poisen into the plants well beforehand, Iv tried giving t it to the plants earlier the last few years this year I'm trying know January so the plants can build up the poison. iv got lots of pots so it will take some time to do them all . I normally make sure the pots are moist before I do them or drench them in water and leave for a few weeks. which I dont normally need to do as I normally keep mulch on top of the pot to retain moisture. so when you apply the poison it stays in the post otherwise you will loose most of it coming out of the bottom. if you've got a few pots this may be enough for me iv got170 pots mostly medium-large and a few small so this product is way too expensive £13 OR more per bottle TO DO ONE POT THIS IS A JOKE a real rip off because the manufacturer knows this is the only product apart from others that have been banned that work the nematode is a total waste of money in the garden they may only good in greenhouses ?? the vine weevils normally come from garden centres from there greenhouses which are where mine come from over 25years ago that's how difficult they are to eradicte maybe if the product was sold for an as reasonable price. like fly spray I could get rid of them forever however the manufacturers will lose valuable customers, this product is only worth at the most £2 per bottle
