I've always used Sevin for tater bugs. Once or twice during the season was all they needed. Best fertilizer for them is one lower in nitrogen like 5-10-10. Phos and potash make the root/taters grow big. The nitrogen is more for what's above ground.
Nailed it .
Be careful with 10-10-10 , best intentions can send tears dow your little fat cheeks .
