Nemasys Leatherjacket Killer nematode treatment (100 sqm)

Nemasys Leatherjacket Killer nematode treatment (100 sqm)

Q: Applied twice over the past month but we still have leatherjackets coming through. How long does it take?

Hi, The nematodes stay alive for up to 6 weeks, so we say to re-apply if needed every 6 weeks. The amount of applications will depend on the size of the infestation, so wait around 4-6 weeks from your last application to check. Kind regards, Lou

Q: How long we can store this at room temperature?

Hi, Once you receive them, please keep them in the fridge otherwise they will not survive.

Q: Ordered last Thursday and still waiting for delivery ! Today is Monday, would the nematodes die in transit with the mixed temperatures ?

No. Nematodes Direct know their business. You can even store them in the fridge when you get them

Q: If I'm not in to accept delivery straight away will the product perish as it presumably wont arrive refrigerated?

The shelf life is on the box I had no problems
