In practice

What plugging
a deck looks like.

Carpenter bees are territorial, so an open hole invites them back. Closing it is most of the fix.

FIRST PASS · FIND THE HOLES

You walk the deck or porch

Carpenter bee holes are round, about the size of a pencil, usually on the underside of rails or eaves.

SAME DAY · PLUG THEM

You press a cork into each hole

Each cork is sized to fit snugly, sealing the hole and repairing the look of the wood.

SAME DAY · PAIR WITH REPELLENT

You treat the surrounding wood

Since bees are territorial, plugging holes while also spraying repellent gives the best odds against new ones.

ONGOING · CHECK EACH SPRING

You inspect for new holes

A quick spring check catches new holes before they spread across the structure.

General-purpose fillers were not sized for this job. A cork sized to the hole is a cleaner, faster fix.

General comparison against generic wood-repair fillers used for carpenter bee holes.

Who buys it

The people who
reach for this.

Four situations show up again and again with carpenter bee damage.

Already has holes

Carpenter bees already drilled in, and you want the damage closed up, not just future bees repelled.

Selling or staging a home

You want the deck or porch looking intact for a showing or inspection.

Prefers no chemicals

You want a physical fix instead of another spray around the house.

Pairs with repellent

You are using Carpenter Bee Repellent and need corks to finish the job on existing holes.

Questions people actually ask

Do I really need to fill in existing holes?

Yes. Carpenter bees are very territorial, so they are much less likely to go into traps or stay away if their existing holes are still open. Plugging with cork is recommended.

What size holes do these fit?

The corks are specially sized to fit snugly into the holes carpenter bees typically drill, about the size of a pencil.

Is cork a good long-term fix?

Yes, cork is a durable, sustainable material that fixes the damage and helps preserve the integrity and lifespan of your deck or porch.

Should I use this with a repellent spray too?

Pairing corks with Carpenter Bee Repellent Spray covers both problems: closing existing holes and discouraging new ones.

How fast does it ship?

Orders are processed within 24 to 48 hours and ship free anywhere in the US, typically arriving within 3 to 8 days.

What if it does not work for me?

Return it within 30 days of purchase for a full refund. Return shipping is paid by the buyer.
