Applied twice over the past month but we still have leatherjackets coming through. How long does it take?
How long we can store this at room temperature?
Ordered last Thursday and still waiting for delivery ! Today is Monday, would the nematodes die in transit with the mixed temperatures ?
If I'm not in to accept delivery straight away will the product perish as it presumably wont arrive refrigerated?

A little bit fiddly and have to keep the product in the fridge before use - but worth the effort. Good outcome and very pleased.

Unreadable instructions - need a magnifying glass

Arrived but not in a box, in a plastic box. instructions were on photocopied A5 piece of paper and took up only half of the page where the writing is so small you need a magnifying glass to read.Clearer instructions are needed so you can accurately read them, even with reading glasses not possible to read worse than going for an eye test we would all fail.Ended up taking a photo to enable reading instructions.

How to get rid of leatherjackets

We had a huge leatherjacket infestation that reared its head early last year as as the full grown larvae ate our lawn. Every time it rained we'd see dozens of them on the patio; dig up a bit of turf and it was chockablock with them.This is what we did, hopefully it will work for others:We applied one round of nemasys immediately (around March), though without much expectation of results as it is most effective on young, small larvae (they hatch in autumn, living and growing in the lawn over winter until they emerge as adult crane flies in summer). We then regularly mowed the lawn (collecting and disposing of the clippings) and kept it free of leaves as autumn arrived as crane flies like to lay eggs in long grass. Finally, in September and October we applied nemasys twice, one month apart, to kill the larvae at their smallest and most vulnerable.We haven't seen a single leatherjacket this year and the lawn looks very healthy, so give this a go!
