Shade

• Scorpions are nocturnal by nature and prefer to hide in cool, shady spots. If a home is located in scorpion-prone areas such as Arizona and is dark and cool with many shady places to hide, it is more likely that scorpions may be nearby.
  
  

Citrus Trees

• While it may not have an apparent connection, if the home has citrus trees or is located near a citrus orchard, there may be more scorpions around. One type of scorpion in particular, the Bark scorpion, likes to live in a wet, shady environment such as an orchard or fruit tree.
  
  

Familiar Territory

• Scorpions are territorial, so one big sign that there may be scorpions present is the previous presence of the little creatures. If scorpions are comfortable, they do not like to leave the area they are in. So if you have seen scorpions in the home before, it is a good sign that they are still there.
  
  

Other Insects

• If you have reptiles in the home that eat crickets or have other insect problems such as spiders or cockroaches, you may also have scorpions. Those bugs are a prime food supply to a scorpion, which will keep coming back for more.
