class=\"faq-item\"\u003e\n\u003ch3\u003eCan I really use the same bottle indoors and outdoors, or do I need separate products?\u003c\/h3\u003e\n\u003cp\u003eStem is designed for dual indoor and outdoor use, so one bottle covers patio, garden, garage, entryways, and indoor spaces. The Pack of 3 option is ideal if you want to keep one bottle inside and one in the garage or mudroom for outdoor application without swapping back and forth.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eWill it hold up in humid, wooded environments where carpenter ants and earwigs are a problem?\u003c\/h3\u003e\n\u003cp\u003eYes. Stem is effective on carpenter ants, earwigs, and other pests common in wooded, high-humidity environments. Apply it around outdoor sliding doors, window wells, basement window wells, threshold areas, and on outside painted trim, brick, and stone. Reapplication outdoors is typically needed every 4-7 days.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eCan I spray it on my hosta plants and other garden foliage to kill earwigs without harming the plant?\u003c\/h3\u003e\n\u003cp\u003eCustomers have successfully used Stem on hosta stalks and outdoor garden plants to control earwigs. The plant-based formula is gentle enough for garden use, and the fine mist provides even coverage on plant surfaces where earwigs hide during the day.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eDoes it work on outdoor roaches and flies around my patio furniture and dining area?\u003c\/h3\u003e\n\u003cp\u003eYes. Stem is effective against outdoor roaches and flies, which is why it's commonly used on patios, porches, and outdoor seating areas. The fine mist covers a decent area with little product, and the light scent is pleasant enough for outdoor dining spaces.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eIs it durable enough to take camping or use on outdoor dining tables?\u003c\/h3\u003e\n\u003cp\u003eThe 12 fl oz spray bottle is portable and well-suited for camping, outdoor dining, and patio use. Its dual indoor\/outdoor formulation means you can bring the same product from home to outdoor recreational settings without needing a separate camping-specific spray.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eI need pest control for my patio, garage, and mudroom — is one bottle enough or should I get the Pack of 3?\u003c\/h3\u003e\n\u003cp\u003eFor multi-zone outdoor and indoor coverage, the Pack of 3 is the popular choice. It allows you to keep one bottle in the garage, one near the patio, and one in the mudroom without constantly relocating a single can. Bulk pest control across multiple outdoor rooms is one of the main use cases for the Pack of 3.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eHow does this compare to outdoor foggers and yard sprays for patio pest control?\u003c\/h3\u003e\n\u003cp\u003eUnlike outdoor foggers that release broad chemical clouds and require evacuation of the area, Stem is a targeted botanical spray applied only where pests appear. It is easier to deploy on a patio before a gathering, leaves no chemical residue on outdoor furniture, and uses a plant-based active ingredient rather than synthetic pyrethroids.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eWill rain wash it away, and how often do I need to reapply outdoors?\u003c\/h3\u003e\n\u003cp\u003eReapplication outdoors is typically needed every 4-7 days, depending on weather exposure and pest pressure. After rain, you may want to reapply sooner. Indoors, reapplication is needed much less frequently, with some customers reporting 4+ months of no ants after a single application using the paper-towel wipe method.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eDoes it stain outdoor surfaces like brick, stone, or painted trim?\u003c\/h3\u003e\n\u003cp\u003eNo. Verified customer reports confirm Stem does not stain bricks, stone, or white painted trim. The fine mist formula is designed for clean outdoor application on common patio and exterior surfaces without leaving visible marks.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eCan I use it around my outdoor dining table without worrying about chemical residue on food surfaces?\u003c\/h3\u003e\n\u003cp\u003eYes. Stem is commonly used around outdoor seating and dining areas. For food-surface peace of mind, you can use the paper-towel wipe method to apply the product to the table legs, umbrella pole, and surrounding frame rather than spraying directly on eating surfaces.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eI'm a Chemical Engineering professional — does this outdoor spray really hold up against conventional yard insecticides?\u003c\/h3\u003e\n\u003cp\u003eStem's entomologist-tested formula is engineered for real outdoor performance, not just indoor use. A Chemical Engineering reviewer reports it works at least as well as Raid for the pests it targets, and it delivers outdoor durability with 4-7 day reapplication intervals while using a plant-based active ingredient instead of synthetic chemicals.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eWill the lemongrass scent bother my guests during outdoor dinner parties?\u003c\/h3\u003e\n\u003cp\u003eMost guests find the light lemongrass and floral scent pleasant, especially compared to the harsh chemical smell of conventional outdoor sprays. It functions as a subtle natural air freshener while actively repelling pests from the seating area, which is a feature rather than a drawback for outdoor entertaining.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eCan I spray it on my garage door tracks and outdoor thresholds where bugs enter the house?\u003c\/h3\u003e\n\u003cp\u003eYes. Spraying on thresholds, garage door tracks, and outdoor entry points is one of the most effective Stem applications. It creates a residual barrier that deters ants, roaches, and other pests from entering the home, and it is safe to spray where pets walk in and out of the yard.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eHow do I apply Stem for an ant trail along my kitchen counter or baseboard?\u003c\/h3\u003e\n\u003cp\u003eFor 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eHow do I use Stem to kill a fruit fly cloud in my kitchen overnight?\u003c\/h3\u003e\n\u003cp\u003eSpray 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eCan I use Stem on absorbent materials like cardboard or cotton balls for mice in the basement?\u003c\/h3\u003e\n\u003cp\u003eYes. 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eDoes Stem work on pests other than ants, roaches, and flies?\u003c\/h3\u003e\n\u003cp\u003eYes. 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eIs the spray bottle compatible with one-handed use or just two-handed spraying?\u003c\/h3\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eWhat's in the box when I order Stem, and do I need to buy anything else to start using it?\u003c\/h3\u003e\n\u003cp\u003eEach 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eWill the spray leave an oily residue on my counters, floors, or other surfaces?\u003c\/h3\u003e\n\u003cp\u003eNo. 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eHow long does the effect last after one application indoors and outdoors?\u003c\/h3\u003e\n\u003cp\u003eIndoors, 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eWhat's the difference between a plant-based botanical insecticide and a conventional synthetic bug spray?\u003c\/h3\u003e\n\u003cp\u003eA 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.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e\n\u003c\/div\u003e","brand":"Knackely","offers":[{"title":"Default","offer_id":48017111187561,"sku":"SH7B09GD81Q4S","price":7.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0778\/8786\/4937\/files\/plant-based-botanical-active-ingredient-derived-from-natural.jpg?v=1788893036","url":"https:\/\/knackely.myshopify.com\/products\/stem-plant-based-insecticide-for-patios-porches-and-garages-outdoor-ant-roach-and-fly-control-12-fl-oz","provider":"Knackely","version":"1.0","type":"link"}
