Toronto Organic Pest Control


If you’re at constant war with pesky creatures assaulting your garden all year long, you shouldn’t immediately reach out for pesticides, even the certified organic varieties (which are neither more effective in pest control nor have a smaller ecological footprint). Instead, you should consider adding certain plants to your garden or backyard to encourage biodiversity and attract beneficial insects that make it their mission to clean your garden of pests and critters.


Nature is filled with good insects whose diet consists primarily of damaging garden pests. Commonly referred to as “beneficials,” they feed on aphids, mites, flies, and other insects that attack plants, being an excellent pest control method, both environmentally safe and free of cost. But in order for these native helpers to solve your bug issues, they need a favorable habitat to thrive, one that meets their requirements of shelter, moisture, food, and alternative prey. A general rule of thumb is to assign up to 10 percent of your garden space to planting beneficial plants that ensure a favorable habitat for the good guys. By shaping the insect ecology of your garden this way, you will be able to minimize pest problems in the long run and also design a beautiful and bountiful garden.

#1. Bee balm – Aside from providing a spectacle of cheerful colors and delightful fragrances, this is a wonderful plant for attracting pollinators and beneficial predators into your garden, including bees, beetles, centipedes, spiders, and butterflies.

#2. Golden marguerite – This outstanding perennial with yellow, daisy-like blooms attracts a wide variety of beneficial insects, including parasitic wasps, lacewings, syrphid flies, ladybugs, and tachinid flies.

Allowing nature to take care of itself in this manner not only cuts down on your workload, but also reduces the insecticides’ impact on the environment. Fewer insecticides means a healthier, safer garden filled with more beneficials and fewer bad bugs.


Remember that beneficial plants are not a quick fix to your pest problem. It may also happen that a beneficial flower attracts beneficial insects in one region, but not in another. Since every garden has its own ecology, it’s necessary to take the time and observe which flowers attract which insects, experimenting to find out what works best in your unique situation.
