If you want a carpenter bee repellent stain, look for a product specifically labeled for use in wood stains and follow its directions; the options here include one paint-and-stain additive plus traps, repellents, and hole plugs. Outlast NBS30 is the closest match for mixing into stain, while Donaldson Farms corks are best for sealing existing holes. The two peppermint-oil products are hanging deterrents, and Brain’s Bee Butter is intended for active nesting holes.
| Product | Best suited for | Type |
|---|---|---|
| Outlast NBS30 | Adding an ingredient to paint or stain | Paint and stain additive |
| Brain’s Bee Butter Trap | Treating active nesting holes | Hole-applied product and trap |
| 36-Pack Peppermint Repellent | Hanging deterrents around outdoor areas | Plant-oil repellent |
| 24-Pack Peppermint Repellent | Smaller quantity of hanging deterrents | Plant-oil repellent |
| Donaldson Farms Carpenter Bee Corks | Plugging existing holes | Cork hole plugs |
Outlast NBS30 Paint And Stain Additive
Outlast NBS30 is the closest fit for shoppers seeking a carpenter bee repellent stain because its listed features say it mixes with both oil- and water-based paints and stains. The product is a 16-ounce additive, not a ready-made stain, so it must be combined with a compatible coating according to the label.
- Best for: Homeowners who already plan to paint or stain outdoor wood and want an additive made to mix into a coating.
- Why it stands out: The listing also says it mixes with water and gives a mixing direction of one pint to five gallons of water.
- Limitation: The supplied product details do not specify carpenter bees, application rates for stain, or how often a treated surface should be renewed.
Check the product label to confirm its intended uses and mixing directions before applying it to a wood finish. Do not assume that an additive provides a particular level or duration of carpenter bee protection unless the label states so.
Brain’s Bee Butter Carpenter Bee Trap
This option pairs a sticky trap with Bee Butter, which the listing says can be squeezed directly into active nesting holes in wood. It is not a stain or a coating for broad areas of lumber. It is a targeted treatment for people addressing holes where bees are nesting.
- Best for: Homeowners looking for a hole-focused approach rather than an additive for a full deck or fence.
- Why it was selected: The listing specifically names carpenter bees and describes applying the butter to active holes.
- Limitation: The directions say not to apply the butter to the holes on the trap itself. Follow the supplied instructions, and treat the claimed duration of more than a year as a listing claim rather than a guarantee.
36-Pack Peppermint Oil Bee Repellent
This 36-pack uses plant oils including peppermint, lemongrass, geraniol, and clove, according to its listing. The repellent comes as balls that can be placed in the provided mesh bags and hung in locations such as a porch, tree, or garden. It is an area deterrent, not a wood stain or hole sealant.
- Best for: Buyers who want multiple hanging deterrents for several outdoor locations.
- Why it was selected: The listing names carpenter bees among the insects it is intended to deter and describes a simple hanging setup.
- Limitation: The supplied details do not establish performance on carpenter bee holes or give a specific replacement schedule. Use only as directed; the listing’s safety statement is conditional on following directions.
24-Pack Peppermint Oil Bee Repellent
This 24-pack has the same listed plant-oil ingredients and hanging-bag use as the 36-pack option. It may suit shoppers who want fewer repellent balls or have fewer locations to cover. Like the larger pack, it is not formulated as a stain, and the listing does not describe it as a treatment for holes in wood.
- Best for: People seeking a smaller quantity of hanging deterrents for patios, porches, trees, or gardens.
- Why it was selected: The listing includes carpenter bees among the targeted insects and identifies plant-derived oils as ingredients.
- Limitation: The product information does not state how long each ball lasts or specify a coverage area. Follow package directions and do not rely on it to repair or seal damaged wood.
Donaldson Farms Carpenter Bee Corks
Donaldson Farms offers 100 cork plugs intended to fit carpenter bee holes. The listing describes them as a way to block existing openings and help prevent bees from returning. Corks address holes; they do not stain or protect an entire wooden surface.
- Best for: Homeowners who have identified existing holes and want a physical plug rather than a spray or coating.
- Why it was selected: The product is specifically designed as a carpenter bee hole filler and is made from cork, according to the listing.
- Limitation: The product information does not provide plug dimensions or establish that every plug will fit every hole. Check the opening and product details before use.
Buying Guide: How To Choose A Carpenter Bee Treatment
Do you need stain, a deterrent, or a hole repair?
Choose based on the task. An additive such as Outlast NBS30 is designed to mix with paints and stains, while hanging peppermint-oil products are intended for placement around an area. Bee Butter is described for active nesting holes, and cork plugs are for filling holes. These approaches are not interchangeable: a plug will not coat a deck, and a hanging repellent will not repair wood damage.
What should you check before mixing an additive?
Read the label for compatible coating types, mixing ratios, application directions, and any surface restrictions. The NBS30 details mention oil- and water-based paints and stains, but do not give a carpenter-bee-specific stain application rate. Do not guess at a ratio or combine products unless their directions allow it.
How should you compare the two peppermint packs?
The listed ingredients and use instructions are similar. The clearest stated difference is quantity: one package has 36 repellent balls and the other has 24. Consider how many locations you plan to hang them, then check the packaging for placement and replacement directions.
Should existing holes be sealed?
Hole plugs are a targeted option when openings are present, but first identify whether the hole is active and follow product directions. The supplied details do not explain how to prepare holes or whether a particular treatment should be applied before plugging. For extensive damage or uncertain identification, seek guidance from a qualified pest professional.
