The Mysterious Dismembered Roach

Roaches yet again. It seems to be what my life revolves around at the moment. Actually, my roommates have gone to the mainland for the weekend on a whitewater rafting tour. I thought, "This will be lovely. I'll have the apartment to myself for a few days." I've lived alone before, and I'm not the type to get lonely from sleeping in an apartment by myself. However, the day my roommates left, I went home at night and felt utterly alone. I was outnumbered by roaches, and wished I had someone else to join in the battle.

The cockroach situation here isn't as bad as it sounds. It's just typical of a tropical island. You'll find a few roaches in the bathroom and kitchen every night, but never in the bedrooms. But this night I was all alone, spraying everything that moved with the black can of death, and dreading disposing of the corpses. Eventually, I managed to kill everything that was moving, and went to bed.

In the morning, I woke up, walked out into the kitchen, and discovered another dead roach. This one was different from the others. I didn't spray any and leave them dead in the middle of the floor, and this one was crushed, dismembered, and smeared into the floor. Now, my roommates are away, so they couldn't have stepped on it. I don't sleepwalk, and I checked my feet for roach guts just in case, but there were none there. So what killed it? What smeared this roach into my kitchen floor?

It could be true that I'm a bit of a pig. When I have no one else to be considerate of and clean for, I tend not to bother. So, there's a dead roach in the middle of my kitchen, and I just kind of walk around it for a day. Last night, I went to bed with the roach in exactly the same place it was when I woke up. This morning, it was further dismembered and eaten (or something). Now I really want to know what's killing roaches and tearing them apart in my kitchen at night!

I don't think one roach would have the power to smear another into the floor. I guess it's possible there's a mouse or a rat, but I see no other evidence of those. Most geckos around here are pretty small, but I guess there could be one freakishly big one lurking around. Finally, there are lots of big iguanas in the area. I'm not sure how anything large enough to destroy a cockroach could be getting into the apartment, but something must be. Ideas, anyone?
