Days went by, and Howard saw fewer and fewer roaches. He didn't like the gecko running around his house all the time, but what's one gecko to a thousand roaches? He shrugged it off, and tried to suck it up. One thing he did do, however, was close the door before he went to bed. But no matter what he did, somehow the lizard always got into his room.

　　One day after work, he was getting some dinner when he saw the gecko chase one of the last cockroaches on the house under the refrigerator. He saw the cockroach scurry under it with the gecko far behind struggling to go under. That's when Harold realized. It was getting bigger. That night he did everything he could to keep the Gecko out of his room. He fell into a deep sleep.

　　All the police found the next morning was a small stain on the bed that looked like blood. They searched everywhere in the house for Harold after a worried neighbor heard a slight scream and a haunting "GECKO, GECKO," that morning, but no one could find anything. No Harold, No Gecko, No cockroaches, nothing. They left that house confused and wondering, never to see Harold again. The only place they didn't check was under the bed, where the gecko was - big as ever, and full at last.

　　日子一天天过去，霍华德家的蟑螂越来越少。其实他并不喜欢壁虎天天在家里跑来跑去的，但是如果不那样的话一只壁虎怎么对付一千只蟑螂呢(但相对于容忍上千只蟑螂来说，一只壁虎又算得了什么呢)？他也只有耸耸肩，尽量去适应了。不过有一件事他还是一直坚持做的，那就是每天睡觉前都会关上房门。但是无论他怎样做，壁虎也总是有办法进入他的房间。

　　一天下班后他正在吃晚饭，只见壁虎正在冰箱底下追着一只蟑螂，眼下屋子里已经没有多少了。蟑螂急匆匆的从冰箱底下跑过去，壁虎在后面也努力的想要钻过去。这时霍华德才注意到，他的壁虎长大了。那天晚上他想尽了办法才把壁虎挡在房门外，随后就沉沉的睡去了。

　　转天早上，警察在床上只发现了一小块污渍，似乎是血迹。有个邻居早晨隐约听到一声尖叫以及让他印象深刻的“咕咚、咕咚”声后报了警，他们为了找到霍华德于是搜遍了整间屋子，但是什么也没发现。没有霍华德、没有壁虎、没有蟑螂，什么都没有。他们满腹狐疑的离开了，但是从此再也没见到霍华德。只有一个地方他们没有检查，那就是床底下，壁虎其实就在那儿——还是那么大，但是终于吃饱了。
