Organic Gardeners' Preferred Squash Vine Borer Control Methods
Sick of finding your squash plants in shambles due to some pesky critters? We've got your back! Stop the disappointment and keep your garden thriving with these 5 effective natural squash vine borer treatments.
First off, let's talk signs. If you spot leaves turning yellow and stems with holes, accompanied by orange-colored sawdust, you're likely facing a squash vine borer (Melittia cucurbitae) infestation.
Got kids or pets roaming around your garden? Synthetic pesticides could pose a risk, and they're not eco-friendly either. So, it's time to go organic! Here are some solutions that'll help keep the chemicals at bay.
Natural Squash Vine Borer Solutions
#1 - Wrap 'Em Up
Wrapping the stem base of your squash plants with aluminum foil, mulch, or even cardboard will make it difficult for adult vine borer moths to lay eggs on the stems.
#2 - Catch 'Em If You Can
Look out for tiny, round, copper-colored eggs congregating on the lower plant stems. The moment you spot them, drop them into soapy water or simply squash 'em.
#3 - Spray Away
Grab some organic sprays like Safer Brand 5163 Caterpillar Killer II, which is OMRI certified, causing no harm to beneficial insects, soil, or earthworms. Bacillus thuringiensis (Bt) is another alternative, a naturally occurring bacterium that tackles the job handily.
#4 - Row Cover
Row covers, thin lightweight fabrics that you lay over the plants, help keep the momma moths at bay and prevent them from laying eggs on your squash, pumpkins, and zucchinis.
#5 - Inspect Regularly
Keep a close eye on your squash leaves, and if you find any that appear limp, dry, or with a hole at the base of the stem, chances are you've got vine borers lurking around. Simply break the infected leaf off at the base, problem solved.
Bonus Tips
- Swap out your regular squash for butternut or Italian tromboncino summer squash as these varieties are less appealing to vine borers.
- Embrace companion plants like marigolds, nasturtiums, and basil, as they're known for repelling vine borers and other pests.
