In the original casita I kept track. Eighteen in four years. Then I sealed it tight. Five in the outdoor bano. The stupid things loved to show up at 10:00PM. Do they have wristwatch alarms? Now I clean them out by switching off the regular lights then blasting them with a custom made 50 watt 365 nm 36 volt chip. They glow bright green. A 50 watt LED chip emits as much power as a 500 watt regular lamp. I place it outside at night and can see scorps 50' distant. Stupid chickens could feast but they will not move out of the hutch after sundown.
The tropics have many x as many alacranes as does the higher elevations and the bajio. I picked 13 off the wall one night, an exterior wall. About 3-1/2 hours.
Despite the best efforts of the tile layer, the tiles in front of the door will be laid flat so a felt door sweep rather then a brush door sweep can be used. Big surprise it's one step up from the rock walk way and it isn't concrete. It's white tile and there will be green half tiles around the door and kitchen window. Above the front door it will be almost a foot lateral distance to the porch. A scorpion had better be an olympic grade broad jumper to make it to the screen door. These plans are far from reality. Everyone is grumbling I insist on a 15 degree peaked roof with terracotta tiles. The winter sun will shine on seventy feet of coiled 150 mm black tubing for hot water. Not a lot of capacity but cold water is more than 70 degrees. Mu shoes fit upside down onto black plastic shelving L brackets next to the bed. I designed new nightlights. 4 ten watt 395 nm led chips set ankle high, powered by s motion detector. Swing feet off bed and the lights come on. If there is a critter about I will know it.
