CORKS 1/2″

CORK 1/2"

CORK 1/2"

PRODUCT DESCRIPTION:    Tapered corks designed to fit and seal the holes created by nesting carpenter bees, ground digging wasps and holes drilled through slabs or walls.

WHERE TO USE:      In holes created by carpenter bees who drill through wood to create nests. After the holes have been treated with Drione Dust, cork them for two reasons: 1) Having the holes sealed will keep the Drione Dust protected so it will last several years. 2) The corked holes will allow you to keep track of the nests you have treated. New holes will be easier to find since they won’t be sealed.

You can also use these corks to seal ground nests built by digger wasps, yellow jackets, etc. Lastly, use these corks to plug drill holes in slabs or wall voids.

RATE OF APPLICATION: One cork per nest.

Will adult carpenter bees drill through the cork?

Hello. We live in Kentucky and have a cedar fence with treated posts. Last year we saw an uptick in carpenter bee presence and now the time to handle. I’ve had a local pest company treat the posts but they claim these old galleries won’t be reused. I disagree so I’d like to dust the holes and plug them as well. The trouble is that most of the holes are on the backside of the post covered by a fence slat, not giving me room for a stationary duster. Can you recommend a good duster with flexible rip that I can maneuver into a 1 to 1-1/2 inch space, then turn 90 degrees. I’m not sure I can even get a cork place where I need to.

At this time of year, what’s the likelihood that it’ll be occupied? I don’t want to get stung.! Oh, and my pest guy wants me to restain the treated posts with an oil-based stain to help retain the pesticide they sprayed.

I’ve watched your videos and want to do the best thing. Suggestions?

Purchased these 1/2″ corks for plugging holes made by carpenter bees. Should have bought more but started with 25, long before I analyzed my problem. After dusting the bee galleries I plugged the holes without incident. These corks are high quality and recommended.

After blowing Drione into carpenter bee holes, I plugged the holes with these corks. Later I pulled the corks out and plugged the holes with tapered dowels that I cut to fit. Then I re-used the corks on the next set of holes.

These little corks are a perfect fit for those drilled holes made by the wood bees. After placing Drione in the hole I waited and sure enough … there were 3 wood bees that crawled out!! Within seconds they died. I waited a few hours before plugging with these little corks. Job done!! Thank you for helping me save my fence!
