you cant really. the soil needs the worms to areate it and provide nutrients. You can use a stiff brush to sweep the soil around. or you could use a dustpan & brush and the soil is excellent for seed sowing.

welcome to GoY too

Thank you, however they are prolific and do not sweep away easily.Is there a chemical (non poisonous) or natural substance that would deter the earth worms or prevent there reproduction ? I am sweeping the lawn daily, but there are still residule mounds which is creating an uneven lawn and smothering the grass.

MOLE'S Steve, fantastic at reducing worm populations. You can have mine if you like, think of it as a welcome to GoY present ;-))

Re Mole`s .Cheers I`ll pass.

wise man Steve, my moles dont leave mounds - - - more like mountains :-( but I never get worms casts ;-) Apparently if there were no worms we would'nt be here, it gets very Bio from there!!

not aware of any chemical control for them. do you have a very fine short lawn? I have noticed they are more prevalent when the soil is warm and moist. Over the winter they will go deeper to get away fro the cold.

what about using a fine tine rake and see if thatprevents the soil compacting in a lump. an old fashioned beesom would work well too.

Many thanks. Will give it a go.

there was an old lady who swallowed a fly i dont know why la la .......... lol bizzy b
worms are a good healthy sign in a lawn and something you will have to live with if you want a lawn stevebath im afraid .
welcome to to goy .

There used to be a treatment to kill worms in lawns, but I think it has been withdrawn from sale, along with a lot of other chemicals. Not that I ever used it, we need all the earthworms we can get, but I agree they can cause a bit of a mess on the lawn, mostly in autumn and spring. If you let the wormcasts dry out, then brush them over the lawn, they're full of nutrients, very valuable stuff. Alternatively, if they don't dry out because the weather's too damp, it's worth considering shovelling them up and placing them on the flowerbeds, don't waste them! Just think of the positives - all that effort-free aeration going on, with free worm compost at the same time...
