Bugs that live in or around electircal equipment
« on: October 23, 2023, 06:44:52 am »
I've seen video's of people repairing computers and TV's, or car's too, that had bug infestations, like ants and cockroaches. One time I was cleaning a doorbell button, and it looked like the two halves should be sealed tight. But it had probably 20 Earwigs living in it, soaking up heat from a little light.

Anyone have any horror stories ?

Infestation of moth larvae in multiple ionisation smoke detectors at a girls boarding house.   :o

Many years ago when I first started out working as a security contractor I was sent out to check an existing system for numerous false alarms. The connected smoke detectors were mounted up high on 14' ceilings so I was using 12' steps and as I removed the first sensor I got completely covered in what initially appeared to be maggots.   ::)

I had some thrips kind insects in the LCD monitor between the backlight and active layer. I  was wondering about the extra "," for quite some time. It got pretty anoying and was not easy to remove. I have no idea why these insects go there - really nothing to eat there.  They are common in picture frames too - so not just electronics.

Long time back on the "material technology" class I learned they (we had some large cable producers here) put special chemicals into the isolation material on cables dedicated for markets outside Europe (they said Africa, but I do not want to discriminate other continents here..).. Otherwise the animals/insects there will eat the isolation stuff as they like it much..

Hundreds and hundreds of ants dead inside the doorbell, to the point that it was no longer possible to push it.
I wonder if the used it as a cemetery, of if they wandered in through the conduit and then... "Hey, what is this wir----" ZOT!
All instruments lie. Usually on the bench.

"Not exactly" a bug but I once found the mummified remains of a small mouse inside an industrial VFD.  It was beyond economical repair - the poor bugger had managed to bridge some phases at the hybrid module and if I recall correctly the gate and drain on the module had been connected too.

In rural areas, hive builders, including mud nests, get inside anything that is protected from weather/predators and open.  They will get inside an electrical box that has just one knockout that is not sealed.

As for non-insects, animals seem to get a buzz out of mains voltages and are attracted to them.  On one occasion, we found a snake across the HV inputs to our home service transformer.  The person from the power company was surprised it didn't blow one of the massive protective fuses.

Back in the eighties I had a clock radio that became the home for a bunch of cockroaches. At the time I was living in the basement of a very old Victorian era house and I guess they liked the warmth. I probably ended up tossing it when I moved.

Had a YAG high power Q-switched pulsed laser that suddenly refused to start.

Overnight a spider built a nest right in the cavity lasing path near the output mirror.
I was lucky the nest was precisely positioned such that the laser did not start, as the power would have killed the mirror and rod coatings from the fried debris.
Removed the nest with a qtip and brought it back to the window sill and spent the next hour cleaning the optics.

I had two good 5.5-digit Fluke bench voltmeters (built in ABS housings) in my basement workspace that were infested by ants.
They both failed:  I assume the ants were attracted by the plastic vapors.
I had to dispose of both of them in plastic bags, and used a boric acid commercial ant product (from Terro) to end the plague.

A local ham brought over a transceiver for me to check out. It was full of live cockroaches which I found after it was on my bench for several hours and I took off the covers. So I bug-bombed it before allowing inside again. It was filthy with nicotine - basically trash as far as I was concerned.

But it was being actively used for ham radio in a house. Don't even think about the living conditions.  :palm:

So the point is he didn't think it was dirty why would anyone else?  :wtf:

Pic attached of it being bug-bombed.
I told my friends I could teach them to be funny, but they all just laughed at me.

1992 in a early job I was working at a small company that did VFD and other motor controller repairs.

We'd get in these centrifuge controllers that came from a honey processing plant.  I never understood how stuff got inside these as they were a diecast enclosure with a gasket and no openings.  The wiring was through liquid tight conduit.

They often had honey inside and dead bee parts.  The techs for sure didn't like working on them!!

In my own house, there is a primitive cellar where the electrical circuit panel is.  It would have been used as a root cellar and canning jar storage in 1918 when built.  I've had occasion to work in the panel and there are always dead centipedes littering the bottom of the box.

Late 1980s my parents bought me an electronic organ (brand new). The thing was in storage for what was probably a very long time, since it was infested with nests or roaches and bugs. Mind you, this is about the size of a large desk, thus it had plenty of room for several colonies.

My dad sprayed its insides, intensely bug bombed the entire house and locked the door behind him - we were leaving for a three week vacation.

Upon return, the carnage was not pleasant but at least they were all dead.

Oh, the "whys" of the datasheets... The information is there not to be an axiomatic truth, but instead each speck of data must be slowly inhaled while carefully performing a deep search inside oneself to find the true metaphysical sense...

I'm glad I took that pic, I've gotten a lot of mileage out of it.  :-DD

Quite recently I had a big ants infestation inside my automatic door bell. It was very labour intensive to remove the little suckers, make it to work again and fill the cavity with solid bug killer product.

I'm sure they're there again!  ::)

I once found a small, dead bird in a fuse panel mounted under the bar of a local cellar disco. The cable duct leading to/from it was so stuffed that nothing could have passed this way. But the double sheetmetal door in front of it was only nearly closed most of the time because it had suffered some distortion and was very hard to close correctly, to say nothing of locking it. Behind that door, the covers over the rows of circuit breakers were missing. So it must have come in by the door or backdoor, hopped in through the incompletely closed doors...and got electrocuted. It was already mummyfied beyond any possibility of identification.
I bagged it and filed it along with my revision report.

I have an open reel tape deck that was buried in the garage for a while.  When I pulled it out one day, I had a look inside to see a full-on colony.

I felt like spraying a fire house at the blighters, but thought better of that idea.  Instead, I sat it out in the sun with a tarpaulin over it to make things a bit toasty, but not excessively so.  The theory was that the ants would vacate to somewhere less "tropical".

I came back later that day and, indeed, they had vacated, taking all the eggs with them.  What was left was comfortably dealt with using a brush and some isopropyl alcohol.  Patience for the win!


Needs a little TLC and component replacement - which seems typical for the model as there is a component "kit".  I'll get there one day.   ::)

A lot of the control equipment I have deployed only gets a visit once a year.

Lots of issues with critters getting in, bugs like the warmth and security, small lizards like the warmth and steady supply of bugs.

Some also suffer from mice (bastards chew the wires) or end up with snakes in them (don’t tend to actually damage much) but only if poorly sealed, and I’m slowly redoing these to make them better.

We use moth balls, surface spray insecticide, and mouse poison to try and keep the gear critter free

I was watching some youtube clips on piano tuning and maintenance...  As it turn out, mouse living inside (acoustic ) piano is common.  I would have thought the noise would have driven them away.  They even live under the keyboard and mummified there.  It was removed by the tech in the clip.

That should be good news once we start eating the bugs.

I live on a very small farm and mice are my biggest nuisance.  Moth balls are said to work, but in some environments, like where there are children  or other small animals that might eat them, they cannot be used.  Peppermint oil also seems to deter mice.  Mice are said to have relatively poor eyesight and use smell.    My "new" shop is in the barn, which has plenty of mice.  Peppermint oil seems to help.  I now add a little to the floor sweep I use in the shop.  That shop is still mouse free after over 4 months.  This Winter will be its biggest test.

As for wires, it is said that common automotive wire attracts them (peanut oil used in manufacture?).  They also went after the ABS system in my truck, which has plastic vacuum lines.  My farm implements are unscathed, except for a few mice nests.
