How do I keep scorpions out of my house?

The steps are many and it takes all of it especially keeping clutter away from your house.

for a quick fix use PCO Choice , YardSafe, or CedarCide for inside. You can use sticky traps for rats too

Keeping a clean and well-organized yard will go along way toward safeguarding your home against scorpions. Vulnerable to dehydration—and therefore extreme heat and sun exposure—scorpions require shady, cool places to hide during the daytime before emerging to hunt at night. Make sure to do the following:

• Keep bushes and small trees landscaped. Do not allow them to overgrow and touch the outside walls of your home—scorpions use these as bridges to enter through windows or other small openings.
• Keep grass & other vegetation short and trim.
• De-clutter your yard, removing all unnecessary items: including brush, debris, decorative rocks, woodpiles, lawn equipment, etc.

Maintain Your Home

Just as crucial as de-cluttering your yard is keeping your home clean and organized. Clean—because crumbs attract bugs which in turn attract predators like scorpions. Organized—because scorpions will use everything from shoes to boxes to piles of clothing to hide. Traditionally cluttered spaces like closets and underneath beds will require attention, too.

Seal Your Home

Scorpions require openings no bigger than a credit card to enter your home. Windows, baseboards, doorways, light-switches, outlets, fixtures, wall & foundation cracks, and even ceiling fans are all potential scorpion entrances. Seal your home by remedying these cracks and openings using caulk (don’t forget to check basements and attics, too!). The same process should be repeated outdoors as well, paying close attention to the roof and any foundation/wall cracks & holes. Screens or seals should be used to ensure windows and doorways remain firmly shut, too.

Eliminate All Excess Moisture

Scorpions are prone to moisture loss and usually enter homes as a way to find water or cool down. Whether inside or outside your home, it’s important to remove puddles, standing water, and any other sources of moisture. Plumbing, basements and crawl spaces should also be kept dry and free of leaks.

Sticky Traps

Those sticky traps used to catch mice and small rats can be re-purposed as scorpion traps. Place them along common entryways, near possible water sources, and in other dark, cool spaces like closets and underneath furniture. Caution: some sticky traps contain synthetic pesticides and other toxins; for the safety of your pets and family, be sure to only purchase the non-toxic versions.

DIY Burlap Trap

A moistened burlap sack makes for an effective scorpion trap. Simply wet the sack and place it in scorpion trouble areas like basements, attics or just outside your home. Leave the bag opened and in place overnight and check it in the morning (be extremely careful when checking both inside and underneath the bag—scorpions pack a nasty sting!). Repeat this process until you no longer see scorpions in or around your home & lawn.

Essential Oils

Lavender, cinnamon, peppermint and cedar are all essential oils said to deter scorpions. These can be diluted with a carrier oil (or smaller amounts of water) and sprayed along scorpion problem areas and entry points—such as baseboards, windowsills, doorways, and around the perimeter of your home.

Spray basements, garages and closets with insecticide. Apply insecticide to any stacked materials where scorpions may hide. Apply synthetic pesticide dust and wettable powder. These substances will kill scorpions before they are able to enter your home.

My husband goes out at night with a can of scorpion poison and a blacklight. The scorpions glow brightly under a blacklight. His idea is to find any in the yard before they can get into the house. We also have an exterminator that poisons possible entry points AND we use sticky traps inside the house in case any sneak in while I am bringing the dogs in/out for their walks. We have to worry about the Arizona Bark Scorpions that have enough poison to kill small creatures like my chihuahua.

We use Home Defense that you can buy at most stores like WalMart. Spray the outside of your home and the inside around windows, doors, etc. There is an open field behind our house so the scorpions are plentiful along with other pests. This has worked great for us. We do this twice a year.
