There’s a New Sheriff in Town

Perhaps the most common question we receive in Garden Centers around the country about Beneficial Nematodes is, “Does it work on …..?”


As in all of nature, the bug world contains both predators and prey. As gardeners, we tend to think of bugs as bad guys or good guys. There are the bugs that eat the fruits of our labor, and there are beneficial bugs that eat those bugs! Since much of the life cycle of harmful bugs happens under the cover of darkness, beneath the soil, we like to think of Beneficial Nematodes as the New Sheriff in town! If there’s a larva problem in the soil, nematodes are Nature’s way of keeping infestations in balance… keeping the “good guys” safe from the pesky beetles and voracious plant -eating enemies of your garden.

Most gardening enthusiasts walk into their local nursery with a specific problem to solve – aphids on their roses, struggling tomato plants with knots on their roots, clouds of fungus gnats, or a shovelful of grubs.

So much of a gardener’s battle takes place beneath the soil – out of view from even the most careful plant parent.

Beneficial Nematodes can come to the rescue, putting a stop to the harmful insects right where they begin.

Stop Garden Pest Crimes with Beneficial Nematodes

List of Pests controlled by Beneficial Nematodes:

  1. Yellow Fever Mosquito: A primary carrier of such diseases as dengue fever, chikungunya, Zika fever, and yellow fever, they feed during daylight, spreading diseases.
  2. Treehole Mosquito: These pests are known to carry various arboviruses that may infect both humans and pets.
  3. German Cockroach: German cockroaches contaminate food and surfaces in homes, also triggering allergic reactions and asthma in adults and children.
  4. Formosan Subterranean Termite: Although not a particular health risk, this invasive species causes hazardous structural damage to buildings.
  5. Winter Mosquito & Northern House Mosquito: These mosquitoes are known carriers of diseases such as West Nile virus and various types of encephalitis, posing a health risk to both humans and animals.
  6. Mexican Fruit Fly: Bothersome to pets and people and destructive to crops, these invasive flies replicate and destroy entire orchards in a season.
  7. House Fly: House flies can carry numerous diseases as they move between waste and human foods. They can spread diseases like food poisoning and dysentery to humans and pets.
  8. Japanese Beetle: These beetles are particularly harmful in that they feed on 300 different kinds of agricultural and ornamental plants. They are highly destructive as they feed on every part of the plant, beginning with the roots, then moving on to damage lawns, flowers, and fruit.
  9. Fire Ant: Working together aggressively, these ants can deliver multiple painful bites and stings that may cause allergic reactions in both humans and animals. Invading homes and yards, fire ants are annoying and hazardous.
  10. Flea: Fleas are parasites that bite humans and pets, causing itching and allergic reactions. They can also transmit diseases like plague and typhus, and parasites like tapeworms, to both humans and pets.
  11. Western yellowjacket: The painful stings of these yellowjackets may also induce allergic reactions. Attracted to human food, they damage homes and yards by nesting there.

We’re sharing this information because we want people to know that they don’t have to simply put up with harmful bugs – there is a solution, provided by Mother Nature. If we work with the earth, we can protect ourselves, our pets, and our planet from both parasites and pesticides.
