Can I just cut off the curled leaves?

You can, but it is better to treat the underlying cause first. If the leaf is severely damaged, removing it helps the plant focus energy on new growth.

Are aphids harmful to my peppers?

Yes, they suck sap and can stunt growth or spread viruses. Getting rid of them quickly is important for a healthy harvest.

Why are my chili pepper leaves curling? Causes and fixes

Check these first

Inspect the undersides of the leaves for small insects.
Check if the soil is dry to the touch.
Observe if the curling happens only during the hottest part of the day.

Likely causes

Aphids
Most likely
How to tell: You will see clusters of tiny green or black insects on the undersides of leaves or near the growing tips. The leaves often look distorted or sticky from the honeydew they leave behind.
What to do: Spray the leaves with a strong stream of water to knock the bugs off. If they persist, apply insecticidal soap or neem oil every 5 to 7 days until they are gone.
Heat Stress
Most likely
How to tell: The leaves curl inward during the hottest part of the day but look normal again in the evening. This is the plant trying to reduce its surface area to save water.
What to do: Provide some afternoon shade if temperatures exceed 90 degrees Fahrenheit. Ensure you are watering deeply every 2 to 4 days so the roots stay hydrated.
