Grub treatment timing

Answer:

Hi Christine,

From what I’ve read, the Milky Spore powder will be most effective when applied in April-May.  However, the neat thing about the product is that if you apply a little later or earlier, the spores still live and  your efforts are not lost for subsequent seasons.  Even cooler, when the  grub digests the spore, the grub will die immediately but those spores will decompose the larva and continue to flourish for years in your turf.

Grub Treatment that isn’t Spore based, like Grub Beater, lasts one entire season, killing overwintered grubs and new ones too.  So it isn’t necessary to time an application with Spring specifically.
