Sprayed safer BT

[Farmerterv]

So I sprayed safer brand B.t. to kill these damn caterpillars. It’s been about 2 days and haven’t noticed much a change. Is it ok to spray again or do you always have to wait atleast a week to spray again? We have had rains and have more rain coming Saturday

You can spray it as often as you want,especially if it's been raining...
The caterpillars have to actually ingest it before it'll kill them,so you need to keep applying it.
The instructions say "apply as needed" so that tells me you can spray it every day if you think it's necessary.
Spraying anything on your plants in the hot sun is not a good idea though,so you should try and spray the plants in the evening if possible,or on the cloudy part of the day.
