As for reading posts they can give bits and pieces to solving problems and many times will not present the complete answer. I know some (females?) are in the house, in the attic - I heard one gnawing away at the wood in my ceiling late last night, probably boring into a joist via the fascia board.īut what to do? Do I treat the many bore holes I see with Drione now? Is plugging with cork necessary? How long should the holes stay corked? Should I also spray in the cracks between the fascia board and the soffit overhang? What will this spraying kill - the living bees, or the larvae? Will I have eggs emerge later, and if so, how much later - weeks, or end of the summer? When, if ever, can I fill the holes or replace the compromised wood? Should I treat with Drione again in the fall, or just use a repellent? Can I fill the bore holes in the fall?Īpologies for so many questions, but while your site is tremendously informative, the exact chronology of when to do what procedure is unclear.Īt 7:42 guest: Sorry for your confusion but I’ll try to answer all your questions as best as possible. I’ve read the first five pages of your posts, but I’m still confused as to the carpenter bee life cycle and the appropriate timing for the different treatments. What should I tell these exterminators to do next? They have told me to call them when I see where the bees are coming in from…but I’m afraid that I won’t be able to find out that information, or that the damage will be more extensive by then…plus, I can’t keep going on with no sleep at night. My kids come in and sleep with me, but I am so terrified that these bees are going to find a way in somehow, or are doing damage to the house, that I can’t sleep at night. The exterminators have been back a couple of times, but we now can’t find where they are coming in from (because they just stopped flying in from the point in the roof that I had seen them go before) and are clueless on what to do next. The exterminators have been up in the attic and sprayed some of them (thinking they were the only ones there), but the ones that we keep hearing in the ceiling in my room are still there, and it sounds like there is a massive amount of them (they only make a “hive” noise when I bang on the ceiling…other than that I hear a strange buzzsaw noise that sounds like an occassional “drilling”). We can hear them in the ceiling of my room, and I have seen them entering the outside of the house through the roof…at one point in time. Even the exterminators we called haven’t been able to identify them (they took samples back with them). We have a large nest and we are not sure what kind of bee it is. Failure to fend them off when you first see activity will usually lead to more and more coming around.įiled Under: LIFE CYCLE OF CARPENTER BEE Tagged With: bee life cycle, bees, carpenter bee, carpenter bee control, carpenter bees, carpenterbees, late spring, males and females Females will live long enough to lay her eggs and maybe even most of the summer but usually not two winters.Īs explained in our CARPENTER BEE CONTROL ARTICLE, they’ll commonly use the same nest over and over which is why nests on structures need to be dusted and sealed. Soon after mating males will begin to die and females will both fill pre existing nests with new eggs as well as drill out new nests following their instinctive behavior to expand the local population. Once it’s warm enough the following spring, they’ll emerge from their nests seeking fresh pollen and a mate. They will use pre existing nests to hibernate and these nests will many times house several bees. As fall turns to winter both males and females will hibernate till the following spring. In late summer they’ll emerge as adults and spend the remainder of the year hunting for pollen. Soon after being laid they’ll hatch and feed on pollen for a month or two before pupating to adults. Here is the “expected” life cycle from start to finish.Įggs are laid late spring to early summer in nests drilled out in dead wood.
