Sprayer ceased to work

If you look at the reviews, "failure to spray" has a frequent walk-on part. Presumably it is just badly designed or built. I overcame the problem by cannibalising the squirting mechanism from an almost empty spray of similar design and fit. Of course, that works so that you can use the contents but doesn't address the design. I was going to complain until I realised what a common fault it was with the product and concluded that it was no use knocking if there's no-one in! Best wishes Fontes

Can it be sprayed on leylandi

0To kill spiders on the trees? or to kill the trees?- I think it only does spiders. ( Elsan, camping toilet bleach on the roots, will kill leylandi)

i sprayed this around the flat very generously, do you think if there was any spiders around they would have come out to run for their lives?

It deff kills spiders , if you spray them directly. Not sure how long it lasts as a deterrent.
