FIRST, I would get very nervous when I see a mouse or a cockroach running out of the storeroom or anywhere else without a sign of pre warning just when such creature is least expected to be around in your anticipation.
I dislike many insects as well. To me, most of them are poisonous and vicious except may be birds (not insects, though), I don't personally or deliberately have anything to do with them. Let them fly freely in the sky or down picking food in my backyard but birds these days tend to get lazier or perhaps smarter. I once left a bunch of bananas in the dry kitchen and to my surprise, a few of them were being eaten or pecked by some birds I assumed. They taught me a lesson to never put any fruit where it's accessible to birds or to attract any uninvited guest to regret later.
Then again, I simply agree, most animals and insects have their instints naturally, to survive, to breed, to build shelters and to have fun, just like us human beings.
Last month, we caught three mice, one at a time after discovering their existence in our house. We must get rid of them at any cost. I bought some sticky glue traps and was successful with only one. What about the two? The answer was "hot water".
I hate to go into details but the mice gave us some proven conclusion. Though they are pests, they too, have their survivor tips, in their own way. They would play hide and seek with their predator, show a few skilful tricks and escape possibly unnoticed. They could fool us a few rounds in silence pretending that they're not around. We almost lost the battle to them. Fortunately, we captured them after much effort and struggle, screams and giggles. Humans are still the winners in the end.
In order to keep away from any disgusting nuisance caused by pests, cleanliness plays the first role. We had since called up the Recycle guys to come and they did us a good job.
I am thinking of turning the storeroom into my private study room soon.
