Larvae (I think!) in garden

You were correct. How do you kill these things?

Watering the soil with a 0.1% solution of chlorophos (an organophosphorus compound that is used as a means of controlling insects.)
The active substance is dimethyl.
The flow rate of the liquid is 0.5 liters per 1 m2.
Also a weak solution is potassium permanganate. But this is a weaker action.

Very nasty stuff. It was sold in the US under the name of Lorsban and Dursban but was banned in 1996.

I've heard about it, but it's being sold here. Often it is a powder or a spray without a smell. I can not say that I use it actively. But when other means are powerless, I buy it.

The ban was later reversed and both are available again.

The Best of GF...what a super team effort everyone

Please send a close up blow up please?

Don't think it's mealworms or the birds will be all around ..

 

[Sheal]

Mealworms are light in colour, so I agree with Alp it's not those. I tend to thing they are leatherjackets but a close up picture would be good.

@zigs may be able to help with this.

If you take a read of page one, mealworms have already been ruled out. It is Bibionidae.

Greetings, welcome to the Forums

There are two families of Fly (Diptera) larvae that are renowned for damaging lawns in the U.K., and elsewhere.

One is the March Flies (Bibionidae) of which the following two species in particular are mentioned as turf pests in the U.K.
• St Mark's Fly (Bibio marci)
• Fever Fly (Dilophus febrilis)

The other is the Crane Flies (Tipulidae), also known as Daddy-Long-Legs in the U.K. Crane Fly larvae are often referred to as leatherjackets. There are numerous species but two in particular are mentioned as being turf pests in the U.K.
• Tipula oleracea
• Tipula paludosa

I suspect the larvae shown in the OP may be Crane Fly (Tipulidae) larvae, but of course it would be best to examine, key out or even rear the larvae to adulthood for a more definite determination.
