The problems with calling in exterminators to deal witha gremlin infestation are numerous.
First, once the exterminator or ghostbuster captures the gremlin in whatever kind of containment trapping unit they use, the boss of the place might demand that they hand over said unit reasoning that because the gremlin was captured on their premises it belongs to them.
Second, if it's a federal installation, those same bosses will insist that the gremlin and unit be handed over though you know that those federal military officials will just use the gremlins for their own military purposes.
Third, even if you make some sort of arrangement with the place's boss over to the phone that's no guarantee that the place will be debugged. The guy might breakdown and cry for your exterminator or ghostbuster services finally caving in to let you keep the captured gremlin. But when it comes time to leave, the guy tells you that such a deal was made while under duress and you still have to hand over the captured gremlin and unit.
The only way to successfully rid your home of gremlins is to do one of the following:
1 Tell them that your technological successes are owed to them, which might just appease their angered cries and make them leave on their own account.
2 Use a chassy car to attract the entire colony as bait, which they won't resist from constantly changing or rearranging until it's too late and they've all been captured in your trap units.
3 Make sure that you, as an exterminator, experienced gremlin handler, ghostbuster, or person greatly versed in matters of mythical creatures, secure a written contract to remove any captured menaces from the infected workplace to ensure a permanent clensing of this small mischievous plague.
