Great! Black raspberries (Rubus occidentalis) are a rewarding crop, but they can attract a few common pests. Here’s a rundown of pest management strategies, from prevention to treatment:

🐛 Common Pests of Black Raspberries

1. Raspberry Cane Borer

Signs: Wilting tips of canes; two rings about 1/2 inch apart near the tip

MANAGEMENT:

Prune canes 6–8 inches below the girdled area and destroy them

Maintain clean borders and remove wild brambles nearby

2. Raspberry Fruitworm

Signs: Holes in leaves; misshapen berries

MANAGEMENT:

Hand-pick beetles if infestations are light

Encourage beneficial insects like ladybugs

Apply insecticidal soap early in the season if needed

3. Spotted Wing Drosophila (SWD)

Signs: Tiny white maggots inside ripe fruit

MANAGEMENT:

Harvest berries frequently (daily if needed) to reduce attraction

Remove overripe or fallen fruit immediately

Use fine mesh netting over bushes as a physical barrier

Set vinegar-based traps to monitor populations

4. Japanese Beetles

Signs: Skeletonized leaves

MANAGEMENT:

Hand-pick in early morning and drop into soapy water

Use row covers in peak season

Avoid traps—they can attract more beetles than they catch

5. Aphids

Signs: Sticky leaves (honeydew), curled foliage, and presence of ants

MANAGEMENT:

Blast with water or use insecticidal soap

Attract predators like ladybugs and lacewings

Reflective mulch can help deter them

🧼 General Preventative Practices

Prune regularly to increase air circulation and reduce fungal and insect issues.

Mulch properly (straw or wood chips work well) to suppress weeds and retain soil moisture.

Keep the area clean—remove fallen fruit and leaves to eliminate breeding grounds.

Rotate planting areas if possible, especially after heavy infestations.
