War Against All Animals

My house has recently become infested with all types of animals. I returned from a vacation to discover that a stray cat had dropped in from my ceiling and then could not get out of my house. I got rid of the cat but think this may have been a mistake because mouse infestation has since become a problem. They are so bad that i will leave my kitchen with a plate of food and when i return with the empty plate there are mice on my table trying to get at the empty pot. I bought rat poison which doesn't seem to be working. When it rains my back yard becomes flooded with water that covers my back porch all the way to my back door. This is very conducive for mosquito breeding. In an attempt to kill the mosquitos the city came around and sprayed houses. What i didn't seem to comprehend while watching bugs fall from the ceiling and walls is that maybe some of these bugs have landed on my bed. The ants that have constructed their hills under my bed did comprehend this. I layed down without looking and was instantly overwhelmed by ants. I moved my bed and discovered the lair. So I boiled a couple pots of water and scorched them. The one animal I have yet to find a solution to are the bats that live in between my ceiling and roof. They don't make themselves visible too much but their screeching throughout the night is quite annoying. My mission now is to kill all animals that dare to enter my house whether they are insects or mammal... I Dont Care, the war continues...
