We get questions about First Saturday Lime all the time!
Please keep asking! We are here to help. Here is a list of answers to frequently asked questions. If the answer isn’t here, please don’t hesitate to contact us via email or on social media.
What is First Saturday Lime (FSL)?
First Saturday Lime is a monthly insect repellent. It is eco-friendly, non-flammable, and has no known health hazards.
How does FSL work?
It is a super strong formula derived from eco-friendly products. It has the ability to dry out insects, eggs and larvae by clogging up the spiracles insects use to breathe and eventually dehydrating them. It creates an inhospitable place for insects to reproduce and thus they leave the area. It is effective as a treatment for infestations, as well as a prevention.
Which insects does FSL repel?
Our product can be used on any insects with an exoskeleton. This includes but not limited to ants, fleas, ticks, mites, lice, aphids, beetles, etc. It also can be used to prevent mosquito growth in water troughs and ponds. Also, many bee farms use our product under their hives to prevent small hive beetles.
Does FSL repel slugs or snails?
Yes, our product works great against slugs and snails.
Does FSL work for ticks?
You can use our product in a yard spreader on the lowest setting to cover the whole yard then wait two days before watering. Our product creates an undesirable dry environment and kills larvae while being safe for kids and pets. It’s best to treat your yard monthly to disrupt the lifecycle.
Is FSL safe to be around for small animals? (chickens, ducks, cats, dogs, rabbits, hamsters)
Yes, First Saturday Lime is safe for animals of any size to touch or have near a feeding source when used as directed.
Is FSL safe around pets? What if they lick it off?
Yes, lime is safe for pets when used as directed, even if accidentally ingested.
What happens after it rains?
The product is insoluble so it dries back out and is again effective. Check the area once a month (like the first Saturday of the month!) and reapply if necessary.
How to Apply FAQ
When should I apply FSL?
We recommend that you apply FSL on the first Saturday of the month. We think this will help you remember to apply it regularly so those bugs stay gone!
How do I apply FSL in the garden?
FSL helps prevent ants, mites, ticks, fleas, aphids, small hive beetles, lice and other pests in gardens. Treat infested areas by dusting plants with FSL. Avoid petals and buds to continue welcoming pollinators. Wait at least 2 hours and gently rinse.
How do I apply FSL to a home, barn, shed, or building?
Apply FSL undiluted in a 2in. wide pour around the outside base of the building structure. This will create a pest barrier. Make sure to check the barrier and reapply if needed every month.
How do I apply FSL in the yard?
Using a yard spreader, cast 1 lb per 20 sq ft of FSL across a lawn for prevention of fleas and ticks. Apply monthly starting in the Spring to disrupt the growth cycle of the pests.
How do I apply FSL to ponds, bird baths, and water troughs?
Apply 1/8” of FSL evenly over the surface of the water to reduce algae and food for mosquitos. Product will permeate water and eventually settle on the bottom. May cause rust if left on metal. Do not use in pools and/or spas. The product is insoluble and may clog your filter.
How do I apply FSL in animal bedding?
FSL can help freshen and deodorize chicken coops, stables, barns, and kennels. Control moisture, insects, and odor by sprinkling 1/8” of the product across the bedding of your choice. FSL can be used on top or under mats. Increase amount until reaching desired effect. FSL may be used as an effective dust bath.
How much FSL should I put in my chicken coop?
We recommend applying a ⅛ inch layer of top of the surface area of the bedding of your choice as well as in the run to combat odor causing bacteria and moisture.
How much product do I need?
1 20lb bag should go around a 2000 sq ft house. (approximately)
Yard treatment: 1 lb will cover a 20 sq. ft. area.
Do I have to apply this every month?
It will be most effective if you reapply FSL every month or when you see insects returning.
Can first Saturday Lime be mixed with any animal bedding?
Yes, First Saturday Lime can be added to any animal bedding to aid moisture control and reduce odors, while repelling insects.
Can I add First Saturday Lime to my pool or sauna?
No. Because First Saturday Lime does not dissolve, it should not be used in pools or saunas. It may clog your pump’s filter. This is true for any system that has a motor and filter, which includes, but is not limited to pools, saunas, fish tanks, hot tubs, etc.
Can First Saturday Lime be used in reptile or amphibian habitats?
Yes, as long as you don’t want any insects to be compromised.
Will First Saturday Lime affect the pH levels in the soil around my trees and flowers?
First Saturday Lime will raise the pH levels of soil to which it is added. pH levels can only go as high as 7. Check with your garden expert to determine if a particular plant or tree benefits or is harmed by a high pH.
My well is near my foundation. Will this harm my water?
No, there are no known hazards with our product. It is approved for organic gardening and for food handling and preparation surfaces.
Can you mix it with vegetable garden soil? Will this hurt my plants?
Yes, you can and no, it won’t! Our formula is safe for plants, pets, and people when used as directed.
How should I NOT use First Saturday Lime?
Here are some things you should not do with FSL.

Why should I use this over other repellents (moth balls/cinnamon/boiling water)?
First Saturday Lime is less toxic than mothballs and is insoluble so will last longer than cinnamon and/or boiling water.
Can this be used indoors?No, we recommend pouring First Saturday Lime on the outside of the barrier of the home to keep away unwanted pests.

In the U.S., the Food and Drug Administration has Affirmed our ingredients to be GRAS (Generally Recognized As Safe).

How is FSL different from diatomaceous earth?
First Saturday Lime is a solution for those who are looking for a non-silica based insect repellent.
How is FSL different from garden lime or hydrated lime that I can find in stores?
Garden lime is very safe, but is full of impurities, which dilute it and cause it to be too weak to be effective. Hydrated lime is very strong and would be an effective pest control, but reacts with moisture which results in burns for humans and animals when in contact with skin or mucous membranes (mouth, nose, eyes). FSL is safe like garden lime, while effective like hydrated lime.
How is this different from ground limestone?
Ground limestone you can find at your local feed store and is called “dolomitic” “quarry lime” or “barn lime.” First Saturday Lime has been in a kiln, made from calcium hydroxide, and formulated to the point that it is concentrated and much stronger. We took hydrated lime and made it insoluble so it won’t cause a chemical reaction when it touches skin or fur. It is patent pending to be the best version of lime that has ever existed.
How is FSL different from other eco-friendly products?
FSL supports all eco-friendly products. We want to work side by side and provide useful solutions to our insect infestations. One main difference between FSL and other eco-friendly products is that FSL has no strong scent. The mode of action of FSL is not to repel by scent, but rather by physically touching the product. This can benefit those who are sensitive to odors or who want to isolate or treat certain plants in their garden without affecting the aroma. Thus you can have your roses and stop smell them too.
