The internet is full of inaccurate information about dermestid beetles.
Hi, by any chance do you remember my last blog post and the
comments I made on poor information that is so prevalent on the internet
regarding dermestid beetles. There is an article out that talks about starting
a colony a colony of dermestid beetles from found wild bugs. The writer goes
into the fact that dermestid beetles are pretty much everywhere in this country
and you can generally find a few on most older carcasses that might be found in
the wild.
Hunting wild dermestids that may have mites is not a good idea.
Those points are true then the article then goes on saying
that sometimes dermestid beetles will be carrying mites and you should check
inspect them to find out if they do have mites. It is also said that you
shouldn’t keep those but if you can’t find any you might be able to remove the
critters from the beetles. Good luck with that.
Now, let’s get to reality. First I really doubt you can hold
a small bug while you lift its hard wings and then his soft wings and look for
TINY little mites way back close to the joints. The fact is - about the only
way to do this in the field is kill the beetle and hope your big old magnifying
glass can let you see what you are looking for. That beetle you just killed will
not do you any good even if it didn’t have mites because you killed it while
looking.
This procedure can be done by professionals but they do it
in a laboratory and anesthetize the bug then look at it under a good
microscope. You ask why a microscope, because
all mites are not the same size! Some mite instars are so small that they look
like a very small piece of dust. You can’t see legs or any identifying features
with a small hand held magnifying glass on these sub adults.
After reading this the first time I laughed because it is
not practical and would be a total waste of time. In other words, it just isn’t
good information but it sounds great! I’m not saying that there isn’t a bug or
two around that doesn’t have mites but those two types of animals live on the
same food sources at the same times. So what are chances that you are going to
find mite free bugs?
It is way better to
buy a started colony than chase around looking for something you are not going
to be able to know for sure isn’t carrying a big problem.
It is best to purchase dermestid beetles form a reputable source.
The internet is full of this type of information so take
what is written and what other people tell you with a grain of salt…or maybe
two grains. In a lot of cases even so called experts and longtime uses don’t
have a clue but they do have suppositions and opinions.
Till next time, Happy bugging!
