Hello,

Budworms can wreak havoc on your dianthus

For treating budworms on dianthus while ensuring the safety of pollinators, you have a few options:

Insecticidal Soaps: These are effective on many plant pests, particularly soft-bodied insects, and are not toxic to pollinators after the spray dries. They need to be applied directly to the pests. More information is at this link:

Timing of Application: Most pollinators forage during the day, so applying treatments at night or in the early morning can reduce the risk of accidentally spraying them. Additionally, removing flowers around the treated plant can significantly reduce the risk to bees and other pollinators. More information is at this link:

Bacillus thuringiensis (Bt):

This microbial insecticide is safe for bees and butterflies when used as directed. It specifically targets caterpillars, including budworms, and is considered a low-impact pesticide

Bacillus thuringiensis (Bt) is a naturally occurring soil bacterium that produces proteins toxic to certain insects. When applied, Bt specifically targets caterpillars, including budworms, while sparing other beneficial insects. It’s an effective and environmentally friendly option for managing pests in your garden.

Bt is a safe option against budworms. Apply it as soon as the first few eggs start to hatch. It targets caterpillars without harming other insects.

Monitor your plants carefully for larval emergence and act promptly with Bt. More information is at this link:

Low-Impact Pesticides: Choose insecticides that are highly selective to a specific type of insect and have low toxicity for others. Look for products with the signal word ‘Caution’ on the label or those designated as EPA Reduced Risk products. More information is at this link:

It’s important to follow the guidelines for the specific product you choose, including the timing of application and any precautions to protect pollinators. Always read and follow the label instructions carefully.

Remember, prevention is key!

I hope this helps!
