What is building this mud turrets in my garden? How to get rid of it please?

[IgboChief]

Greetings!

 

Long story short: What is that and how can I get rid of that?

It makes my garden unmaintainable during the raining season. Mowing the lawn becomes very tedious and one night later they start to build up again.

Looks like you have worms , and you don't want to get rid of them,

they are very good for your garden, the casts are free fertilizer ,

this only happens in rainy season ? right , they are getting a bit waterlogged .

Stupid boy !  Imagine goat dumps on the lawn.   I have a lawn but no worm casts nothing left by my 2 cats either , oh sometimes a piece of rat maybe.

Fantastic pictures! Can't help with the problem though. ????

In the meantime I found it out: these are Cicada chimney built by Cicada nymphs during the raining seasons to prevent them from drowning.

 

This makes sense to me since I have many large trees and deafening cicada noise every summer.

 

I was advised the cover the most infested areas with insecticides (SEVIN or Reclaim IT) and will do so now because it became an unbearable problem.

Put a tot of whisky into a watering can, water the lawn evenly.

The grass comes up half-cut.

Do you have dogs?  I don't use chemicals on my lawn because of them.

[crazykopite]

At least there not termite mounds

Does the dog help me to mow?

I thought that too but have been proven wrong: we have actually compost areas with earth worm (up to 50 cm beasts), but not a single chimney there.

Also, I dug a few up and found the nymph.

I know, and its no light hearten decision.

But these chimneys are quite big, up to 25 cm and it takes them only 3-4 days to build them.

 

I have a beast of a lawn mower, with 30 cm rotating blades, which blunt completely after one hour mowing. When the soil is wet, it is dense enough to stall the engine. When it is dry it will turn into dust choking the engine and me. I have to maintain almost 3 Rai and its no joke.

 

During the rain season, the grass here grows like 10 cm in 3-4 days. Regular mowing is key or it gets out of control. So sorry, these beast have to go.
