Im not sure if this is a bug or what

I was going outside to clone all of my plants and I saw this on the underside of my strawberry banana plant leaf. It looks like a bunch of little suction cups kind of I don't know how else to describe it I mean I'll post the picture maybe somebody can tell me what this is because I don't have a clue.

Thanks for the photo — yes, those are definitely insect eggs, and they appear to be lepidopteran (moth or butterfly) eggs, most likely from a caterpillar pest, such as:


Suspected Pest

• Corn earworm (Helicoverpa zea) or cabbage looper types are very common in cannabis.
• The yellow-orange color, oval shape, and tight cluster pattern are classic indicators.
• They were laid directly on the underside of a fan leaf, which is common behavior for caterpillar-type pests.

What To Do Now



Immediate Actions
It’s good to have multi IPM for bugs and mold, but also to gain sucess of resist issues to boosting the plants ISR. it’s good to mix some but also rotate weekly. Always read manual on such and test

1. Remove that leaf entirely and destroy it — don’t just wipe it.
2. Inspect nearby plants and leaves, especially:
   • Undersides of upper and middle leaves
   • New growth areas

️ IPM Treatment Recommendation

Spray ASAP (and repeat every 5–7 days if needed):

• Venerate XC – 2–5 Tbsp/gal (insecticidal bacteria; kills eggs and small larvae)
• Suffoil-x @2-5 T per gallon ( suffocation/ low stress / no resistance/flower allowance )
• Grandevo WDG – 3–4 tsp/gal (deterrent + insect growth regulator)
• DES-X – 2% dilution (suffocates soft-bodied insects)
• Optional: Bacillus thuringiensis (Bt-k) if available — highly effective on young caterpillars.

Avoid spraying oils like SuffOil-X during high heat or sun — especially when using microbial products — to prevent plant stress.



Prevention Tips:

• Regularly foliar spray bioinsecticides during early and mid flower (avoid when buds thicken).
• Add Regalia weekly to increase systemic resistance.
• Consider a light UVB zap or sticky cards if adult moths are present.

Short answer, without all the AI clutter - use BT spray (bacillis thuringiensis). It’s a beneficial bacteria that targets caterpillars. You can buy it ready to use, or mix your own from concentrate.

If you have other critters, an insecticidal soap can be used, up until the plants start flowering. BT can be used safely throughout flower if needed, but you’ll want to do a budwash at harvest. It’s something that’s been used on food crops for decades.
