I had to defend the perimeters the other day when I came home in the afternoon to find this beast getting ready to invade my lovely domicile. There is a wet spot around it because I doused it with "kinchouru" mukade-insecticide. It was still sort of twitching, so I took up a trowel and made sure to finish the job. Bleargh!
I took the precaution of spraying also around my door and mail slot. Sometimes when people leave newsletters and things in the slot, they roll them up and leave them sticking out. It's like an invitation for some horrible crawly thing to slide right on in.
