Our product can be used on any insects with an exoskeleton.

Is FSL safe around pets? What if they lick it off?

How to Apply FAQ

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.

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.

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 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)

Can First Saturday Lime be used in reptile or amphibian habitats?
Yes, as long as you don’t want any insects to be compromised.

How is FSL different from diatomaceous earth?
First Saturday Lime is STRONGER and SAFER than diatomaceous earth. Diatomaceous earth is made from silica, which can cause respiratory inflammation in humans and animals. It is essentially ground up shells that repel by “cutting” up insects. First Saturday Lime has had the silica burned out of the product and has ZERO known health hazards. There are respiratory hazards when using diatomaceous earth but none with our product. First Saturday Lime is approved for use on food contact and food preparation surfaces… but it tastes terrible so we don’t recommend making a meal of it. :-)
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 just as safe as garden lime, while as effective as 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 strongest and safest version of lime that has ever existed.
