hollyhock weevils

I have way too many hollyhocks to check them all. last year I spent hours hand picking weevils. Is there anyway to kill them before the plants really start growing? its almost impossible to rake up all the buds on the ground. I cut and removed all the old stems but I think the bugs are in the tinier dried up buds, is that right? are the seeds themselves infected? I love these plants and those bugs ruin them.
thank you, maggi in NM

You can spray neem oil any time of year. This can be used as a spot treatment, and a pre-treatment, and preventative. Just make sure to spray this while in shade, or in the afternoon to avoid burning the foliage.
