Wax Moths

- I have this hive that the wax moths are trying to take over.
I have cleaned the wax moth cocoons out three times and they keep
building back. Is there anything I can do?
- I put my frames in the freezer three days and still got wax moths. What is wrong?
You did not state the extent of the damage or the condition
of the bees, so we will make several interrelated assumptions. Wax moths have been exceptionally active
this year and this is always the case in a year of drought when the bees are
under stress. The wax moth attack on
your hive is nature's way of cleaning out the weak hives. Your problem is the queen, and the moths are
the symptom, not the problem. Strong
hives can ward off wax moths under normal circumstances, and 2002 has certainly
not been normal, so the wax moths did what they were supposed to do. Much earlier in the summer one should notice
a decrease in the house bee population during the peak of the day or the work
hours...(don't rely on the bees hanging out on the front late in the afternoon
to indicate the overall population). Yes, I know we can all get otherwise occupied and fail to pick up on
subtle clues, but they are there. Often
are heard such things as "my hives are pollen bound or honey
bound." Again there is a queen problem.
A healthy, vibrant and balanced hive will experience
no such thing.Any over-exuberant
activity in storage of either indicates a queen that is in a weakened condition
due either to natural or non-natural events.
Certain strains shut down nearly all brood activity in late summer and
prepare for winter in a different fashion than, say, the typical Italian that
most beekeepers are used to seeing.Bees in this country are, from a DNA standpoint, mutts...therefore one
sees variations on late summer patterns of behavior all over the rainbow.The main point being that mid-and
late-summer inspections generally reveal irregularities.Rule of thumb is to look to the queen.
Catch this in time--requeen.Catch it a little later, one might get away
with combining hives.Any later, then
get ready to clean up the mess and get the box ready for next year.
Let's cover two questions. First, frames with drawn comb that have had brood in the cells
is the most susceptible to wax moths, as their prime concern is the cocoon and residue left from
brood which is embedded in the wax of the cell and covered with a very thin layer of fresh wax
by the workers preparing the cell for the next cycle. Left unprotected, the moths will try to get
at it, even with bees in the hive. The best ongoing defense is always a good strong colony of
healthy bees with additional ventilation screening. As to the freezing, the whole conglomeration
must be at 0 degrees F for three days. First one must determine if the freezer will go to this
temperature empty before and frames are processed. The easy way is a simple digital unit used
to measure inside and outside temperature. Place the bulb or thermocouple between the
innermost frames of the whole super. In other words, say one has four supers in the freezer,
lower the bulb to the center of the mass between the center frames. In a frost-free freezer, the
desired 0 degree should arrive at about the second day. A non-frostfree needs three days for
heat transfer to level at 0 degrees. NOW, start your three-day count at that point. Even this is
not an absolute unless you live in Saskatoon, Canada where such temperatures occur naturally
for longer periods.
Second: In the case of frames for cut-comb honey, it takes an addition 2 to 2.5 days for the
honey to reach the desired 0 degrees. That's a total of 8 to 9 days to be safe. PLUS, if you
have no dehydrator to use when the frozen boxes are removed you must place each box
(super) in a plastic bag and seal it before freezing then allow the whole thing to thaw out in the
sealed bag to room temperature before opening and processing the cut comb. No one ever
said cut comb was as simple as in the good ole days when folks understood that from time to
time critters do hatch out on the store shelf and sometimes after purchase. It was a natural thing
and still is, but it's now no longer politically correct, therefore must be regulated,
documented, registered, inspected, vacuum packed, hermetically sealed and sufficiently taxed to
cover THEIR cost, but one must keep all these folks happy with cheap food no matter the
consequences. (Have to exercise my "hot button" from time to time.)
Added note: If one objects to chemicals in any form, the above is about the only way in this
area and the South to help curb the wax moth. If one does not object to chemials, then
Paradichlorobenzene (PDB for short), marketed under the trade name of Para-moth, is the
standard. There are some bootleg methods out there, but DON'T DO IT. The stack needs to
be sealed top, bottom and at each super or box. If sealed with tape I recommend a PDB
treatment on a shallow container for each approximately 4' stack. A paper plate at each mark
will work, but one must open the seal to check the chemical, then reseal. PDB will evaporate in
less than 3 weeks in our current heat. There are several drawer devices available from supply
houses, or I will show anyone a shop-made unit that I use. Avoid storage in damp, dark and
dead air spaces at all cost. NEVER in a dead air basement, stall in a bank barn, laundry room
or the kitchen pantry (the latter should be self-explanatory). BEFORE use, the boxes should be
carefully checked for any spillage and aired a couple of days. This stuff is deadly to bees.
