Beneficial nematodes are microscopic organisms widely used in the pest control industry. Various nematode species can be used to kill bugs, termites, and other insect pests.
So how can you use it? How can you guarantee its efficacy? Read on our full post to the answers.
Beneficial nematodes come in three different species. Each one has different behaviors and is used for specific insect pests. These are the following:
Widely referred to as Sf, this beneficial nematodes species is commonly used to control pest fly population as well as other insects like fleas, mites, and bugs. It’s also a common choice for eradicating a flea infestation.
This can come anywhere between 5 million to 100 million nematodes per pack.
This beneficial nematode targets the larvae of soil-dwelling insect pests. Sc is also effective against fleas, German cockroach, fruit flies, codling moth, Subterranean termites, and more.
Hb nematodes are naturally occurring organisms on the soil, but only in small amounts. For this nematode to work its magic on insect pests, it has to be applied lavishly.
Overall, it targets Japanese beetles, weevil, grubs, cucumber beetles, red imported fire ant, and more.
How does it work?
So how do beneficial nematodes take care of business? Once deployed, these organisms will hunt for the fleas and other insect pests. Technically, these nematodes are roundworms which will feed on the body of the host.
Beneficial nematodes will enter the body of the insect through the mouth, anus, or its skin. Once they gain entry, the nematodes will now feed and release gut bacteria that are poisonous for the host. The insect pest will die within 24 to 48 hours upon the entry of the nematodes.
Once the nematode is done feeding on the dead insect, it will exit and continue to look for another host. This is why nematodes work continuously in eradicating an insect pest as long as they are applied correctly and in an ideal location.
Even if nematodes are deadly for insect pests like fleas, it doesn’t harm crops, furry pets, and humans. Also, it’s very rare for beneficial nematodes to trigger allergies or irritations if handled well.
Nematodes can be used both indoors and outdoors, but the application will vary.
Do all nematodes kill fleas?
All the three nematodes we mentioned above (Sf, Sc, and Hb) are known to kill fleas. Some suppliers of beneficial nematodes will try to blend these types to cover more insect pests.
Aside from the species, you should also mind the application of beneficial nematodes. These organisms are light-sensitive and they need to stay within a moist place. Storage is also crucial to ensure that the nematodes will remain alive and active.
Are nematodes harmful to humans and pets?
Beneficial nematodes are proven to be safe for humans, kids, and pets. These organisms only feed on specific insects and therefore wouldn’t harm the beneficial insects if used outdoors.
In fact, beneficial insects were proven to be immune to the nematodes. With this, nematodes will only kill those that are considered as pests.
Aside from that, the Environmental Protection Agency (EPA) has exempted nematodes from federal registration. It’s a testament that this is safe to use, even on edible vegetation.
Also, you no longer have to keep the pets away when applying these organisms. Unlike chemical flea solutions, nematodes aren’t abrasive.
Using nematodes to kill fleas
For this part, we will teach you how to deploy the nematodes properly. This way, the organism will work at its full potential. Here are the simple steps:
What you need:
Step 1. Purchase the right nematodes
Make sure that you purchase the right nematodes that kill fleas. If you have no clue where to get yours, we’ve reviewed two options below that you can buy now.
Take note that nematodes are sensitive to heat and light. If possible, purchase it from a provider nearest to you and can guarantee that the shipping process won’t kill the organisms.
Step 2. Mix the nematodes with water
Once you have the nematodes, mix it into the water on a bucket. Mix the amount that you’re going to apply within 30 minutes. Nematodes that are mixed in water for more than that timeframe will die and lose its flea-killing abilities.
Also, let the nematodes sit on the water for a minute or two before transferring it to the spray bottle.
PRO TIP: Mix nematodes on a dark place. If possible, deploy the organisms at night and in tap water. In addition, extreme temperatures can quickly kill the nematodes.
You can also use a watering can or hosepipe for this.
Step 3. Spray or douche it on the affected areas
After transferring the nematode water to the spray bottle, apply it right away. It’s best to add two drops of food color on the mixture, so you’ll know if you’re already running out of supply.
Also, shake the bottle in between sprays so the nematodes will be applied in equal concentrations. For outdoor spaces, you’ll need to soak the ground with the nematode-infused water.
If you’re applying this indoors, spraying it directly on the affected areas will do. For those who are thinking of spraying the nematodes directly to their pets, it’s best to ask the opinion of a veterinarian first.
Overall, nematodes aren’t used on humans or pets, so it’s better to avoid it as well.
Step 4. Re-apply as necessary
Depending on the weather on your location, you’ll need to re-apply the nematodes. For outdoor locations with very dry weather, you should re-apply the nematodes every three days for up to two weeks.
You can also spray it once a day indoors depending on the extent of the infestation.
The re-application will ensure that the nematodes will be conditioned well on the application area. It also sustains the flea protection for you and your pets.
How long before the nematodes work?
Nematodes will usually kill fleas within 24 to 48 hours once they start feeding on it.
If you’re looking forward to massive results, you’d have to wait for two weeks with regular application. Even if the nematodes come in millions, they still need time to locate the fleas and make a dent on its population.
If the nematodes didn’t seem to show results after the said timeline, you should tap the help of a flea expert. You might be applying the nematodes wrong or that the organisms are already inactive or dead before the application.
Once the fleas are eradicated or if the nematodes can’t find a new host, it will die. This prevents the organisms from being the next pest. Also, the nematodes will decompose, leaving no trace behind after the infestation.
Take note that the efficiency of the nematodes relies on how you store it. Since these are live organisms, you should only shelf nematodes for a short period. Furthermore, keeping them stored for a long time will result in their death.
Also, you have to understand that nematodes need food in order to survive. If you want to stretch the nematodes’ lifespan, it’s best to store them in the fridge. Take note: the fridge, not the freezer.
It’s best to cover the nematode container with aluminum foil to protect them against the light. Again, nematodes hate the light and they will die if exposed to it for long.
Under this condition, the nematodes can live for up to 14 days. Nevertheless, you should factor in the length of storage and delivery of the nematodes even before you put it inside the fridge.
It’s best to use nematodes as soon as possible. If you need more supply, just re-purchase new nematodes.
To make sure that you’ll get the right nematodes and it will work against the fleas, make sure that you keep the following points in mind:
-Nematodes can’t function well in freezing temperatures. If you’re facing a flea infestation during winter, nematodes aren’t the best option. These organisms can’t work well if exposed to extreme temperatures. Aside from that, fleas become dormant during the winter season, making the nematode treatment less efficient.
-A fishy smell on the nematodes is a bad sign. If you opened the packet or container and you smell a fishy scent, the nematodes may be already dead. The fishy smell is the odor of their decomposition. There’s no point in using such nematodes.
-Always purchase from a reliable seller. If possible, purchase the nematodes from a seller that hasn’t stored them for too long. This way, you can still keep the nematodes for a few more days.
-Apply the nematodes right away. The moment that you open the container and mixed the nematode with water, you have to apply it fast. This way, the nematodes won’t die and starve.
Where to get beneficial nematodes?
You can purchase beneficial nematodes on most gardening and home supplies stores. Just make sure that the seller is keeping the nematode supply fresh. If the nematodes have been in the store for more than two weeks, it’s likely to be dead or inactive.
If any of these stores aren’t available in your locality, you can opt for our two options below. These are tried and tested by many gardeners, homeowners, and even pest control experts.
