Hello 😀,

Last year my garden, especially the flowers on my petunia plants were majorly infested with caterpillars. Iam not sure what kind. I could go out in the morning and catch about twenty each day. So far this year I haven't yet had an infestation but I think as it gets warmer they will come back. I already sprinkled bug and caterpillar killer in my garden but Iam not sure if that is why I haven't seen them yet. They would ruin the flowers and take chunks out of the leaves. Does anyone have any ideas on getting rid or them and what kind of pest they are???

Any ideas would be greatly appreciated!!!

Sometimes an invasion doesn't repeat the following year so fingers crossed. To know what they are we would need to see a close-up photo if they come back. If they're caterpillars for sure as opposed to sawflies (the larvae look similar but the latter are not caterpillars), you could treat with Bacillus thuringiensis (Bt).
