Best Insecticidal Soap For Roses: 10 Sprays Compared

#1 · Best Overall

1. Monterey Insecticidal Soap RTU

Best for: Ready-to-use organic gardening.

Why it ranks #1: Ready-to-use and OMRI listed, it names aphids, whiteflies, mealybugs, spider mites, and thrips among its targets and includes a garden measure spoon.

Monterey’s ready-to-use soap is OMRI listed for organic production and includes a garden measure spoon, a useful pairing for gardeners who want a prepared spray plus a measuring aid. It targets soft-bodied pests on fruits, vegetables, ornamentals, and other plants.

The 32-ounce RTU spray works on contact against listed pests such as aphids, whiteflies, mealybugs, spider mites, thrips, and scale, making it relevant to rose foliage where these pests appear. Monterey says it works within minutes of application and can be used on edible plants through harvest day. Its indoor and outdoor gardening use supports varied plant settings, while the included spoon adds a measuring accessory. The supplied information also calls for protective eyewear and thorough washing after application.

Skip it if you want a concentrate for preparing larger batches; BioAniquile is a concentrate that makes up to 130 gallons.

Monterey suits rose gardeners seeking an OMRI-listed ready-to-use soap for ornamental and edible plants, with a measuring spoon included. It calls for protective eyewear during application, a relevant consideration when choosing a spray routine.

#2 · Best Coverage Guidance

2. Garden Safe Insecticidal Soap Spray

• Form: Spray
• Warranty Description: Warranty

Best for: Ready-to-use garden sprayer.

Why it ranks #2: Its ready-to-use directions call for spraying all plant parts, including leaf undersides, and its listed pests include aphids, mites, and thrips.

A ready-to-use 32-ounce contact spray removes the mixing step, so rose gardeners can move straight from spotting pests to treating foliage. Garden Safe says insects must be sprayed directly for control, making thorough coverage—including leaf undersides—central to using this formula effectively.

The spray can be used indoors, outdoors, and in greenhouses on flowers, ornamentals, shrubs, and gardens, which suits rose care across several growing settings. Its ready-to-use format avoids dilution, while the adjustable nozzle offers spray or stream application. Treating both leaf surfaces matters because the product works by contact; apply in calm weather, avoid full sun, and avoid rain forecasts for 24 hours. It can also be applied to edible plants through harvest day.

Skip it if you want a concentrate to mix for repeated batches; Safer 5118-6 is a listed concentrate option.

Choose Garden Safe if you want a ready-to-use spray for roses among flowers and ornamentals, with indoor, outdoor, and greenhouse use. It requires direct pest contact and careful coverage, so reach leaf undersides and avoid full sun.

#3 · Best Ready-to-Use Range

3. Bonide Insecticidal Soap

• Form: Spray
• Warranty Description: DISCLAIMER OF EXPRESSED AND IMPLIED…

Best for: Broad garden pest coverage.

Why it ranks #3: This ready-to-use spray uses potassium salts of fatty acids and lists spider mites, aphids, and thrips among a broad range of pests.

Bonide’s ready-to-use soap lists an unusually broad range of targets, from aphids and spider mites to caterpillars and weevils. That variety may suit rose gardeners managing mixed garden pests, while the contact-action formula means insects and infested plant surfaces need direct spray coverage.

The spray is intended for outdoor residential use in home gardens, ornamentals, and greenhouses, so it can fit rose beds and other listed garden plantings. Its ready-to-use format arrives without a mixing step, and potassium salts of fatty acids from plants kill insects on contact. Bonide also states it may be used on flowers and up to harvest day on edible plants. Direct application is important; it is not a systemic treatment according to the supplied description.

Skip it if you need an indoor-use option for houseplants; Garden Safe Insecticidal Soap Spray lists indoor use.

Bonide suits rose gardeners who want a ready-to-use outdoor spray with a wide listed pest range and use on ornamentals. Its stated setting is outdoor residential use, so choose another listed option if indoor rose treatment is essential.

#4 · Best Concentrate

4. Safer Insect Killing Soap Concentrate

• Form: Spray
• Warranty Description: Warranty

Best for: Concentrate for seasonal spraying.

Why it ranks #4: The OMRI-listed concentrate targets aphids, mealybugs, whiteflies, and spider mites, with directions to reapply every five to seven days while pests are present.

Safer’s 16-ounce concentrate lets gardeners mix spray as needed, a practical choice for rose care that involves repeat applications. Its directions call for treating at the first sign of damage and reapplying every five to seven days while insects remain, giving the routine a clear cadence.

This soap targets soft-bodied pests including aphids, mealybugs, whiteflies, leafhoppers, and spider mites, all relevant to a gardener assessing damaged rose foliage. The concentrate must be mixed with water as directed, so it suits buyers comfortable preparing each batch rather than reaching for a ready-to-use bottle. Safer lists flowers, shrubs, and other plants among its uses and identifies the formula as OMRI listed for organic gardening. Thoroughly cover plant surfaces during application.

Skip it if you prefer spraying straight from the bottle without dilution; Monterey Insecticidal Soap RTU is ready to use.

Safer fits rose gardeners who want a mixable soap concentrate and can follow a recurring treatment schedule. Its label directions call for applications every five to seven days while insects are present, so it is less convenient for instant, unmixed use.

#5

5. Garden Safe Insecticidal Soap

Best for: Plant-derived fatty-acid soap.

Why it ranks #5: This plant-derived fatty-acid soap kills bugs through contact and may be used up to harvest, though the listing gives fewer application details than its RTU counterpart.

Garden Safe identifies plant-derived fatty acids as the basis of this insecticidal soap, giving rose gardeners a concise ingredient distinction for contact pest control. The product kills bugs through contact and may be used on edible plants up to the day of harvest.

Contact action means the spray needs to reach the insects, so careful coverage of rose foliage is central to its stated use. Garden Safe presents the product for organic gardening and says it may be used through harvest day on edible plants, which can matter when roses share space with a vegetable garden. The supplied product details do not specify a container size, dilution rate, or application interval, so the listing offers less workflow detail than some alternatives.

Skip it if you want explicit directions for recurring applications; Safer 5118-6 specifies reapplication every five to seven days while pests remain.

Garden Safe fits rose gardeners seeking a plant-derived soap for contact control, particularly where edible plants are also grown. The supplied listing is brief and does not specify a dilution rate or treatment interval, so review its directions before planning repeat use.

6. Bonide Captain Jack's Super Soap

• Form: Spray
• Warranty Description: Warranty

Best for: Outdoor multi-pest treatment.

Why it ranks #6: The outdoor ready-to-use spray targets aphids, spider mites, and thrips among more than 30 listed insects and mites, and also lists powdery mildew.

Bonide Captain Jack’s pairs insecticidal soap with a claim of control for more than 30 insects and mites, making its broad target list the key appeal for outdoor rose gardens. The ready-to-use spray avoids mixing and is also described as controlling powdery mildew.

The product is specified for outdoor residential use in home gardens, ornamentals, and greenhouses, so it can fit rose beds alongside other listed plantings. Its direct-contact action means gardeners should spray where pests are present rather than expect protection without contact. The listed uses include flowers, herbs, vegetables, fruits, and container-grown plants; Bonide also describes it for organic gardening. It is a ready-to-use spray, though the supplied information does not provide a rose-specific application interval.

Skip it if you need a soap explicitly listed for indoor use; Garden Safe Insecticidal Soap Spray includes indoor applications.

Choose Captain Jack’s for outdoor rose beds when a ready-to-use formula and broad pest list are priorities. Its stated use is outdoor residential gardening, and the supplied details do not give a rose-specific application schedule.

#7

7. NatureStop Insecticidal Soap

• Form: Liquid

Best for: Peppermint-oil foliage spray.

Why it ranks #7: Its peppermint-oil formula is designed for soft-bodied pests including aphids, spider mites, and mealybugs, but the listing supplies limited application specifics.

Peppermint oil is the named ingredient in NatureStop’s liquid insecticidal soap, giving rose gardeners a clearly identified botanical formula for direct foliage application. The product is aimed at soft-bodied pests such as aphids, mealybugs, and spider mites, common targets for gardeners inspecting leaves.

NatureStop directs users to spray affected foliage and surrounding plant surfaces, a straightforward workflow for treating visible pest activity on roses. Its listed targets include aphids, whiteflies, spider mites, and mealybugs, so the product is positioned for soft-bodied insects rather than a general-purpose claim against every garden pest. The brand describes it as suitable around families and pets when used as directed. The supplied information identifies a 16-ounce liquid but does not specify a dilution routine.

Skip it if you want a product with a stated repeat-treatment interval; Safer 5118-6 specifies every five to seven days while insects remain.

NatureStop suits rose growers seeking a peppermint-oil liquid for direct treatment of visible soft-bodied pests. Its listed instructions focus on foliage application, while the supplied details do not establish a mixing rate or recurring schedule.

#8

8. Trifecta Crop Control

• Form: Oil

Best for: Large-volume edible-crop spray.

Why it ranks #8: The 128-ounce plant-based formula targets aphids, spider mites, and whiteflies, but it is an oil-based blend rather than a straightforward soap spray.

Trifecta’s 128-ounce bottle offers a large volume of plant-based spray for growers treating roses alongside indoor or outdoor plants. Its listed targets include spider mites, aphids, whiteflies, and fungus gnats, while the formula is described as biodegradable and suitable for edible crops.

The product is presented for crop, garden, and houseplant insect control, giving it a wider setting range than a strictly outdoor rose-bed treatment. Its plant-based formula lists thyme, clove, garlic, peppermint, and rosemary oils, among other ingredients. Trifecta says the spray suffocates and dehydrates pests and can be used on edible crops without chemical residues. The 128-ounce size may suit gardeners with substantial treatment needs, but its supplied information does not state a dilution ratio.

Skip it if you need a stated repeat interval and mix instructions; Safer 5118-6 provides a five-to-seven-day interval and mixing directions.

Trifecta fits growers treating roses as part of a larger indoor or outdoor plant collection, especially when a 128-ounce format is useful. The supplied facts do not state a dilution ratio or repeat schedule, so check those needs against the product directions.

#9

9. BioAniquile Soap Concentrate

• Form: Lotion, liquid

Best for: Botanical concentrate with cinnamon oil.

Why it ranks #9: This concentrate combines potassium-based soap with cinnamon oil and lists several soft-bodied pests, but the supplied details do not establish rose-specific directions.

Cinnamon oil joins potassium-based insecticidal soap in BioAniquile’s concentrated formula, combining contact pest control with additional botanical modes of action in one bottle. For rose growers, that means a single product is presented for insects, mites, fungal control, and repellent activity.

The soap targets susceptible soft-bodied pests, including aphids, whiteflies, mealybugs, thrips, and mites, on contact. Cinnamon oil is associated in the supplied description with fungal control, mite control, and insect-repellent activity, extending the formula’s stated uses beyond soap action alone. The 33.8-fluid-ounce concentrate makes up to 130 gallons, which can suit gardeners preparing multiple batches; however, it requires dilution and careful measuring rather than immediate bottle-to-plant spraying.

Skip it if you want a ready-to-use bottle with no batch preparation; Garden Safe Insecticidal Soap Spray requires no mixing.

BioAniquile suits rose gardeners who want a concentrated botanical formula with soap and cinnamon oil, plus multiple stated modes of plant protection. The make-up-to-130-gallons claim entails dilution, so it is not the pick for direct spraying.

#10

10. Ferti-lome Spinosad Soap

• Form: Oil
• Warranty Description: No Warranty

Best for: Ready-to-use outdoor pest control.

Why it ranks #10: Its ready-to-use outdoor formula lists many insects, but its spinosad-focused pest control is less directly aligned with a rose-focused insecticidal soap choice.

Ferti-lome’s ready-to-use spinosad soap lists a broad range of outdoor pests, including aphids, beetles, caterpillars, and leafhoppers. That breadth can appeal to rose gardeners dealing with more than one listed insect, while the no-mix format keeps preparation simple.

The product is specified for outdoor use on flowers, shrubs, trees, fruits, vegetables, lawns, ornamentals, and greenhouses, covering several settings where roses may be grown. Its ready-to-use format removes concentrate mixing, and the label directions say to spray leaf surfaces or locations where insects are present. The listed target range extends beyond soft-bodied pests to caterpillars and beetles. Always read the label before use, as the supplied description directs, and follow its full insect list and application instructions.

Skip it if you need an indoor-use option for roses in a sunroom; NatureStop lists use around families and pets when directed.

Ferti-lome suits outdoor rose growers who want a ready-to-use product with a broad listed insect range, including chewing pests. Its stated use is outdoors, so it does not fit indoor roses; consult the label for the complete target list and directions.
