Cabbage white butterflies ( Pieris rapae ) are easily identifiable , as they ’re a creamy white gloss with a few dark acid towards their flank ’ outer edges .
If you ’re in North America , northern Europe , Australia , or New Zealand , and you discover these lovely white pests exhaust your bok choy , you ’re probably dealing withPieris rapae .
They have slightly larger full cousin that live in southerly Europe , Asia , and North Africa , know as bombastic white cabbage butterflies ( Pieris brassicae ) . The methods for fending them off are identical , so you could use the same techniques whether you ’re in Texas or Turkey .
They ’re quite small , and since they ’re not as showy as most other butterflies , they ’re often mistaken for moth . Females gravitate towards plants that are puritanical - park in chromaticity to put down their testis , and which plant tend to have those colors in nigga ?
That ’s right : cabbages , kale , etc .
How to Identify Cabbage White Butterfly Infestation
Well , this one is fairly self - explanatory : if you see these insects flutter around your plant , they ’re undoubtedly laying eggs on them . And if you of a sudden see a cluster of gape holes all over the plants ’ leave , they ’ve not only already laid eggs — they’ve hatch .
These larvae do n’t just munch on your plant ’ leaves . They like to tunnel down into gelt hearts and Brassica oleracea italica head , rendering them discolored , sludgy , and unusable .
If you do n’t catch the eggs and larvae early on , you ’re probable to lose a ton of your own food to them , so be sure to act quickly .
The intellect why the larvae can do so much damage to your crops so rapidly is because of orchis diffusion .
clams butterfly figured out that laying just a couple of testis per foliage rather than all on one foliage meant that their caterpillars had a swell chance of survival of the fittest . This is because they are n’t competing for solid food , and less chance of all being taken out by a single vulture .
Speaking of vulture , you ca n’t depend on bird to facilitate get free of these caterpillars for you , either . Your chickens might be of huge help in stay fresh slugs and snail aside , but not these .
Brassicas all have sharp - tasting mustard oil in their stems and farewell . This basically “ savor ” the larva that eat on them , which make them quite unappealing to predators .

Row Covers
I did n’t pop out usingrow coversuntil this year , and so help me , I wish well I had started year ago . I ’ve lost myriad works to sneak white butterfly , and all that exit could have been avoided .
Yes , setting up row covers is a turn of a pain to start with . Just trust me when I say that the results are well deserving the sweat and back nervous strain .
For fend off cabbage white butterflies , you may either use butterfly stroke netting or a fine mesh . The veiling is unremarkably inglorious and creates a sloshed grid that they ca n’t go by through because of wing size . This prevents the butterflies from position eggs on the undersides of your plants ’ leaves .
The downside to this gauze is that it does n’t offer much aegis if your plants get really great .
Unless you make row cover supports that are raised quite high off the ground , you launch the risk of infection of tall genus Brassica like kale , collard greens , and rapini labor up against the net income . If that chance , the butterflies can still get to the foliage .
I utilize very all right mesh overcompensate instead , and they work wonder . Truth be told , some of my covers are really repurposed mosquito veiling ! The net I had around my bed got some tears in it during storage , so I just dissever the net in two , sewed the holes shut , and covered my kale and rocket .
play like a magical spell .

Plant brassicas that you do n’t find particularly tasty around the perimeter of your covered vegetable . The best location is more or less a metrical unit aside from the bed . I used leaf mustard ( Brassica juncea ) , but you’re able to use any member of the chou family .
Just do n’t imbed material that you really like , because it ’s going to get massacred .
These craw are stringently decoys to keep your favorite plants safe , so be disposed to see them completely sacrifice . If you find that they ’re good , however , be sure to plant some extras .
naturalize them in other areas and have them go to seed . That path , you could replant them the following year wherever take , especially if you practice regular craw rotary motion .
Insecticidal Sprays
Do you likegarlic ? I love it .
Cabbage blanched butterflies do not . As such , you’re able to put this glorious electric-light bulb to great consequence to get rid of them .
