Whatever.

The nematodes will only survive above 5C.

WRONG. Quote from Nemaslug Nematodes are capable of surviving the odd
frost; so don't worry if the temperature falls after you have applied
Nemaslug

The time for application is when
you can guarantee that below 5C is not likely at nights or daytime.

WRONG. You can apply just before planting which usually is for most
gardeners in the spring, as explained above, unless you're called
Rupert obviously.

Applications every 6 weeks (not 3) is the recommended dosage by the
reputable manufacturers.

WRONG. The nematodes are active for 6 weeks. Reapplying is 3rd week but
not all products do need re-applying.
