The sounds of my daughter having a meltdown in the next room because her dad sprayed some ants in the back yard.
She can't bear to have anything die, even ants or mosquitoes.
Yup, been there.
Once the yearly ant invasion entered my daughter's bath while she was soaking, though, she began to see the brilliance of spraying the little bastards.
Actually, we don't get the tiny ones. We have a massive wood ant colony that overwinters beneath our driveway. They are usually one half inch in length or more and they always come up under the house first, looking for water. They make their way into the house and our only defenses are to make sure that there is NO water for them to find and poison the bastards, when you see them.
I was appalled to find that they had found the tub, while my daughter was soaking and listening to her music one day - some time in March - and there were at least two hundred of the pests, drowning in her bath water. My first clue was her blood curdling scream.
(not to worry; they don't bite or sting. They gather wood to feed the molds which in turn feed their captive herd of aphids, which they milk for food) I have been quoted a price of fifteen hundred dollars to drill under my driveway at an angle and exterminate them, permanently. That seems ridiculous, since after a couple of weeks of annoyance in spring, they have burrowed to other sources of wood and water.
I would rather just kill the ones that make it into the house, to be quite honest.
