carpenter bees up under wood trim

by

hi my question is for the last 2 years now i have noticed these carpenter bees going up under my wood trim on top of the side of my house.  then all i can see is the sawdust falling out as they are drilling. upon looking under the trim, i cannot seem to see the hole they are making, it is very tight under there. i cannot take the trim off, due to the electrical lines being hooked up. i know i need the drione dust, and a sprayer. my question is, even after i spray the dust, how am i supposed to plug the holes i cannot see. the trim is 6″ wide. not only can i not see there holes i cannot get my fingers up in there to plug them. now the wood peckers are starting to drill like crazy. my siding seems to be spared, i do not no why, it is a hard clapboard seeder looking board. the ground to the top of the trim is about 25 feet, please help? thanks  john

CORKS are only needed to enable the DEMISE DUST to last as long as possible. In fact there is no doubt the Demise would solve your problem and even without corking the bee nests you’ll still get fairly long protection. Here’s why.

When treating carpenter bee nests out in the open, leaving the treated hole as is will allow lots of air flow which in turn will depreciate the treatment. Instead of 6-12 months of residual, you may only get 1-3 months. The corks can also serve as markers so you’ll know which nests have been treated, which ones still need to be dusted and which holes have been newly drilled.

When treating up under soffits, facia boards and other wood trim bees will sometimes access, it’s many times impossible to dust directly into their nests. But because many of these entry ways will be so well protected from you, they’ll also be well protected from the weather. In cases like this we’ve seen where dusting can last 3-6 months no problem and sometimes even longer. I suspect this would be the case in your situation.

In summary, there is no need for worry or concern about not being able to cork their holes. In fact, if you were to dust once in the spring and once in the fall, I’m sure you’ll be able to keep this pest under control and avoid costly damage to the rest of the house that’s sure to start if you allow the situation to continue. As the Demise video demonstrates, this dust is light and airy and only a little bit can go a long way at both killing and repelling carpenter bees. I’m sure any applied to the cracks and crevices you have in this wood trim area will do the job.

  1. hi, thank you for your prompt responce. i also wanted to tell you, what looked like droppings along my siding from up under there i didnt no if it was the bats or the carpenter bees. because i have a p window sized vent were bats hang out. but i think this is bee droopings not sure of thee colors, as they have been there a while now.
    can you suggest which dust sprayer i should get for my situtation. about 25 feet from ground, under the trim sideing of house tight spaces as i said. do you recomend b and g? or dustic etc? and will the tips i need already be with the duster if i plan to do it from ground. i can use ladder, but i thought you said the female bees have stingers, will the attack? thanks again, john

    • @john: In general the males will do all the “attacking”. Fortunately they’re ill prepared to do any real damage and are essentially harmless. But having bees flying around you while trying to dust atop a ladder is not good. To avoid this and other hazards (bees, physical injury, etc.), I strongly recommend getting the Dustick seen here:

      www.bugspray.com/catalog/products/page1406.html

      It’s easy to use and will enable you to dust all the way around your home quickly and efficiently. As stated above, I believe treating twice a year would be the smart thing to do and getting a Dustick will really enable you to do the work on this kind of schedule without too much stress or strain. This assures you’ll stay the course too. Also, this unit comes complete with the only tip you’ll need to do the work. Good luck!
