- You're gonna have to maintain a decent supply of Yukkuris through some means, which will definitely cost time, money, or even both depending on where you live. - You'll have to clean up each mess after you stop the alarm. - You're gonna have to store these critters somewhere and wherever it is, it will surely be noisy and annoying having to put up with them clamoring to get out, go home, eat, etc.
