you could net them off to stop the butterflies in the first place .

But if they do get on there, I'm afraid the best way is to don the old gloves and go out every day in caterpillar season and squish them. I used to worry that there wouldn't be enough butterflies left in late summer for my buddleias to look great, but there always is.

We still have a few flying around but I don't think they are laying eggs now, too cold, as the plants are growing leaves again, the ones I did protect, I did with netting over wire hoops.

You can also spray with garlic spray which deters the butterflies etc. from ever getting near the veggie plants and acts like a systemic. Too late for this year though.

This will also keep vampires out of your brussel sprouts lol.

Doesn't keep me away! I love it!

I'm with Nariz on that one.

im definatly not a vampire lol . its good for pets too as it stops fleas and mites etc .

Garlic is extremely good for you helps with all sorts of aliments and problems and as Nosey says good for keeping fleas etc. off pets.
