Frequently Asked Questions
I run a clean, eco-conscious home — does this fit a non-toxic lifestyle?
Yes. Stem is made with only essential oils and a plant-based active ingredient, with no added dye, no synthetic fragrance, and no harsh chemical odor. It is designed for households that prioritize non-toxic, plant-based living without sacrificing pest control performance.
Will the scent disrupt my wind-down routine or meditation practice at home?
No. Users describe the scent as a light floral or lemongrass aroma that is calming rather than overpowering. Many wellness-minded homeowners actually appreciate it as part of their evening routine, since the fresh scent doubles as a subtle aromatherapy element while keeping pests out of relaxation spaces.
Is this safe to use in spaces where I do yoga, reading, or other mindfulness practices?
Absolutely. Stem's plant-based formula and fresh essential-oil scent make it well-suited for yoga rooms, reading nooks, meditation corners, and other personal wellness spaces. It controls pests without introducing the harsh chemical odors that would disrupt a mindful atmosphere.
Does it really kill pests effectively, or is the plant-based formula a trade-off for performance?
It does not sacrifice performance. Stem's entomologist-tested formula kills roaches within a minute (they shrivel up), eliminates ant trails with one or two sprays, and clears fruit fly infestations overnight. A reviewer with a Chemical Engineering degree reports it works at least as well as Raid.
I prefer essential-oil-based home products — is this made with real essential oils or synthetic fragrance?
Stem is made with only essential oils — there is no added synthetic fragrance whatsoever. The light floral or lemongrass scent comes directly from the botanical ingredients, which is also why the smell itself acts as a deterrent for spiders and rodents.
I'm a wellness-focused homeowner — is this safe enough to use in my bedroom where I read and unwind each night?
Yes. Stem is ideal for bedroom use in wellness-oriented homes. The plant-based formula, light essential-oil scent, and absence of harsh chemicals make it appropriate for personal relaxation spaces. Many users spray it in corners, on ceiling fans, and around windows as part of their evening routine.
Can I use it in my bath area or near where I keep my essential oil diffuser?
Stem can be used in bathrooms and other personal-care spaces for ant and roach control. Because the formula is plant-based and made only with essential oils, it complements a wellness-focused home environment that already incorporates aromatherapy and natural products.
How does this compare to essential oil DIY pest sprays I make at home?
Unlike homemade essential oil sprays that vary wildly in potency and rarely kill pests on contact, Stem is an entomologist-tested formula with a standardized plant-based active ingredient. It delivers consistent contact-kill performance (roaches within a minute) plus residual repellent effect, while DIY sprays typically only offer weak, short-lived deterrence.
I don't want harsh chemical smells in my home — is this completely odor-free or does it have a scent?
Stem has no added synthetic fragrance or chemical odor. Instead, it carries a light, pleasant scent from its essential oil ingredients, most often described as floral or lemongrass. Most users consider the scent a benefit rather than a drawback, and it dissipates cleanly.
Does the lemongrass scent actually repel spiders and rodents, or is that just marketing?
It is a real functional benefit. Lemongrass is widely known in botanical pest control to be despised by spiders and rodents, and Stem's lemongrass-infused formula creates a residual deterrent effect. Customers report that even after the spray scent dissipates, the spatial repellent quality remains.
Is this product a good fit for someone who avoids all synthetic chemicals in their home?
Yes. Stem is specifically formulated for users who want effective pest control without synthetic chemical exposure. The active ingredient is plant-based and the formula contains only essential oils — no synthetic pyrethroids, no added dyes, and no artificial fragrances.
I invest in clean-air home products — will this spray affect my indoor air quality?
Stem is designed to preserve indoor air quality. The plant-based formula contains no harsh chemicals or synthetic fragrances, and the light essential-oil scent dissipates quickly. Unlike conventional bug bombs or aerosol insecticides, it does not leave persistent chemical residues in the air.
Can I use it in my bedroom where I sometimes eat to keep ants away without spraying near my food?
Yes. The paper-towel wipe method is popular for bedroom and snacking-area use. Simply spray Stem onto a paper towel and wipe it along baseboards, window sills, and ant trail entry points. This keeps the product off surfaces where you eat while still eliminating ant activity for weeks at a time.
How do I apply Stem for an ant trail along my kitchen counter or baseboard?
For ant trails, you can either spray directly along the trail where you see ants traveling, or use the paper-towel wipe method: spray a paper towel with Stem and wipe it along the baseboard or counter edge. Both methods eliminate ant activity, and many customers report 4+ months of ant-free results from a single wipe application.
How do I use Stem to kill a fruit fly cloud in my kitchen overnight?
Spray Stem directly into the air where fruit flies are clustered, typically near fruit bowls, trash bins, or drains. A single nighttime application is usually enough to clear a severe fruit fly infestation by morning. The fine mist covers the area efficiently without leaving residue on kitchen surfaces.
Can I use Stem on absorbent materials like cardboard or cotton balls for mice in the basement?
Yes. Spray Stem onto wet cardboard, cotton balls, or other absorbent items and place them in areas where mice travel, such as unoccupied basements, garage corners, or along wall edges. This discreet placement method controls mice without spraying open air in living spaces and allows for easy cleanup.
Does Stem work on pests other than ants, roaches, and flies?
Yes. While the primary label targets ants, roaches, and flies, customers and testing confirm effectiveness on yellow sac spiders, earwigs, fruit flies, gnats, carpenter ants, and mice. The lemongrass ingredient also acts as a residual deterrent for spiders and rodents even after the spray scent dissipates.
Is the spray bottle compatible with one-handed use or just two-handed spraying?
The 12 fl oz aerosol or pump spray bottle is designed for easy one-handed operation. A short press delivers a fine mist that covers a decent area, making it practical for quick spot treatments in kitchens, bathrooms, and along baseboards.
What's in the box when I order Stem, and do I need to buy anything else to start using it?
Each order includes a 12 fl oz spray bottle of Stem Botanical Insecticide, available in Pack of 1 or Pack of 3. No additional accessories are required — the bottle is ready to use straight out of the package. For application method variety, you may want to keep paper towels on hand for the wipe-application technique.
Will the spray leave an oily residue on my counters, floors, or other surfaces?
No. Stem's fine mist formula is designed to leave no oily residue. If you prefer, you can use the paper-towel wipe method: spray onto a paper towel and wipe along surfaces. This delivers full pest-killing performance while keeping the spray entirely off visible surfaces — ideal for kitchen counters and food-prep areas.
How long does the effect last after one application indoors and outdoors?
Indoors, Stem typically lasts significantly longer than the time stated on the bottle — multiple customers report 4+ months of ant-free results from a single application. Outdoors, reapplication is generally needed every 4-7 days due to weather exposure, with the lemongrass ingredient providing a residual repellent effect between applications.
What's the difference between a plant-based botanical insecticide and a conventional synthetic bug spray?
A plant-based botanical insecticide like Stem uses an active ingredient derived from natural plant extracts and essential oils, rather than the synthetic pyrethroids and chemical compounds found in conventional sprays like Raid. The key difference is that botanical formulas avoid harsh synthetic chemicals, added dyes, and synthetic fragrances while still delivering contact-kill pest control — entomologist-tested and verified to work as effectively as leading synthetic brands.
