A Complete Timeline of Arizona’s Scorpion Season

Scorpions are more than just a nuisance to have around your home. They are dangerous creatures that can harm both you and your family. It’s important that you know methods for keeping them out of your home and understand when they are most likely to be looking for shelter inside your home. So here is a full-length timeline of the Arizona scorpion season and where scorpions are most likely to be at every time of year.


September to October

Around this time of year, temperatures tend to drop from the blazing heat and humidity of July and August. As nights become cooler, scorpions begin to look for shelter indoors, which is why it’s crucial to seal your home before this time of year, rather than after you notice a couple of these unwelcome visitors. Additionally, keep a close eye on your doors. Scorpions tend to be sighted around exterior doors this time of year and inside garages as they seek winter shelter.


November to December

During the winter months, temperatures get cool, especially at night. Scorpions begin to winter down, looking for places that are warm and dry to wait out the winter. Homeowners also tend to take a break from pest control because there are fewer pests around to begin with. It’s very common to find scorpions inside the home at this time of year, not because they are active but because they can be unintentionally disturbed.


January to February

In the dead of winter, scorpions are very inactive. If there are significant freezes, they will enter a state of diapause, meaning they will go into dormancy. Scorpions have an incredibly low tolerance to the cold, and if they have already wintered down somewhere warm in your home, they are likely to stay put. This is the time where the fewest sightings of scorpions in the home are made. However, if they are disturbed, they will certainly become active. The most common places for scorpions to hide out are under duct work or near heaters. Keep in mind that if winters are warm, scorpions and other pests will become active earlier.


March to April

As temperatures warm up, scorpions and other pests become more active. As this is also pest control season, keep in mind that the use of pesticides can flush scorpions indoors to escape the spraying. Additionally, any scorpions who have found comfortable places to hide in your home are unlikely to venture out while the spraying is going on, but will also be more active. This makes it even more crucial that your home is proofed against scorpions to prevent them from ever entering your home.


May to June

When the temperatures get hot and humid, scorpions tend to move more slowly to conserve energy. They also look for cool places to escape the heat meaning, you guessed it, in your home! Keep up with your house proofing and your pest control efforts throughout the summer and prevent scorpion infestations in your home.


July to August

This is the time of year when scorpions are at their most active. This is also the busiest time of year for pest-control companies so scorpions are coming into contact with more applied product and scorpions will try to escape indoors if they come into contact with the treatment. Be vigilant within your home and work with us to repair any openings that scorpions might be able to use to enter your home. Call us at GreenShield Pest Control (520-393-3352).

    I recently moved to Arizona on my own without knowing a soul here. Before moving, I had read a lot about Arizona, but strangely, nothing about Bark Scorpions. I found out about them the hard way after living here for only one month, I stepped on one with my bare feet that sent me to the hospital. The pain was excruciating. It affected my whole body and neurological system. Severe pain lasted 24 hours. Obviously I pulled through, but nothing I’d ever want to experience again to say the least. It would be nice if there were more awareness about that awful creature.

    Thank you for sharing this great article!

    I had a similar experience after moving into our new home. Ended up in the ER. Couldn’t see or walk. My whole body twitched for hours. It was very painful and only old people and children get the antiveniom. I had numb arms and legs off and on for a good month. I’d be normal and suddenly my legs would go numb and give out. A nightmare! You need to SEAL up your house and hire a scorpion removal company. Nothing else works – no other exterminator worked to rid us of them.
