BioLogic Ecomask Beneficial Nematodes, 5 Million Steinernema carpocapsae (Sc) Nematodes for Natural Flea Control Plus Easy to Use Hose End Sprayer (Value Pack)

I got this product with high hopes. Fleas have been increasing steadily over past few years. In past I have had professional exterminators with little success. I sprayed lawn with commercially available products, treating home, pet areas and pets at same time. I have used IGR in home and yard. All products seem to decrease flea population for limited time only. Irregardless of what label says, with or without IGR, I rarely get a few weeks of decreased fleas. It is becoming cost prohibitive. I'm worried about the environment as my and pets health with this increase in pesticides. I found out about nematodes doing a search for a better, safer and healthier way to get rid of fleas. I'm giving this 5 stars because the package arrived with cold packs still cold. This with temps near 100 here in South Central Texas. From my reading, I know that these may not work due to the excessive heat this time of year. I plan on giving it a try anyway. FYI; FOR THOSE LIKE ME WHO KNOW NOTHING ABOUT APPLYING NEMATODES. Apply evening. Aerate soil if possible. A pitchfork works fine. (1) Use amount of water needed for application method and substitute food coloring for nematode amount. Apply solution to area. This will show time needed for application, how much/little your technique is applying thus avoiding missed areas. (2) Nematode mixture must be cool. Depending upon outside temps and device, you may want a cold pack in or around it. (3) Moist ground is a must. Apply after a rain or water well before and as indicated after to help nematodes get established. Nematodes hunt their food. Moist soil will helps them. (4) SHAKE, AGITATE MIXTURE FREQUENTLY during application. Every site stated nematodes mix sinks. Without good shaking, depending upon application method, the question is when device will clog not if. I have high hopes for this method. EDITED 8/23/2017: I have a dramatic decrease in fleas. I'm impressed by the quick response that I had. I do want to say that last month I applied pesticide and IGR to yard twice about 2 weeks apart. I had only a brief decline in fleas. Home and pets were treated at same time of those applications. I applied these beneficial nematodes just over 2 weeks after that. I got them as a last resort for fleas. Due to no rain, I watered ground twice (12 hours apart) before application of nematodes. I watered ground again 3 days later. I also applied nematodes heavier in dog's outside area and all areas that stay shady. I also treated house and pets at same time. Wish I had found out about beneficial nematodes a long time ago! Edited 12Feb2018. It has been about 6 months since applying nematodes. I can't say when but I noted before cold weather set in that my dog was no longer bringing in fleas from outside. I noticed that we were going from weekly flea baths for dogs and indoor cats to every other week to monthly. The progress was slow but definite! I plan on repurchasing and applying this again.

We had two really horrible summers with fleas, and I HATED using all the chemicals/sprays plus the lotions, potions, and pills on the fur babies--seemingly to no avail as the problem did not go away. Dogs, cats, and humans were miserable. Not only that, but all the flea traps in the house served as an immediate advertisement that our home had a problem. This year, we ordered and applied these nematodes right before the summer heat and flea season kicked in. I can't begin to tell you how happy we all are. Our dogs, cats, and home are all flea free. It's amazing! The neighbors are still having problems, so I don't think this is a fluke. I wish these nematodes worked on ticks, but it's definitely worth purchasing for the flea protection alone!

I've long been a fan of nematodes, but last year was particularly cumbersome with fleas, chiggers, the works. I know this is not designed to kill everything I was throwing at it and yes, I got professional green pest control in home but this is what I used outside on my 1/3 ac area I frequent the most of the 2 ac of forest lands I own. HIGHLY recommend. CAVEAT: you cannot use together with poisons. If you choose to go toxin free, this is the most fabulous product. The company delivers great service and superior information for the new or confused buyer :)

The nematodes have saved me so much money and hassle regarding fleas with my dog; however, the sprayer is poorly made, and the black part that screws onto my hose broke before I could even use it. I got soaking wet while applying, but had already mixed the nematodes and needed to apply them to my lawn. I wouldn't waste your money purchasing this particular sprayer, but would recommend buying another one that hooks up to your hose. Using a gallon pressure pump sprayer put me in lots of pain (arms and back). I wish I could see how to contact the seller to get a replacement sprayer as I've already used up the nematodes and cannot return the whole product. I was hoping to use it several years in a row, and just buy the nematodes each year.

This is the third time I bought BioLogic Ecomask as I am extremely allergic to fleas. Whenever I am outside the fleas jump on me and bite me. Fleas can transmit many diseases including lyme disease. My indoor cat was infested with fleas in the past and I realized that I was the one bringing the fleas inside my house. After doing extensive research I kept reading about beneficial nematodes and found this product and decided I had nothing to lose by trying it. 1 year ago (May 2019) I bought it and followed the instructions completely. Yes, if you don't follow the "exact" instructions it will not work. You must refrigerate the product once it arrives, you must water your property beforehand, aerate the soil/lawn. Spray the nematodes after the sun goes down and be sure to water your property again after spraying. The Nematodes go into the earth and start spreading killing flea larvae. I re-applied this product in August of 2019 NOT because I was bit by any fleas but because I wanted to make sure that I would not. I did not get bitten once last summer nor do I bring any fleas inside my house. I just used this product last night because that's how well it works. If you're on a budget this product is still cheaper then using chemicals, going to your vet, and getting treated for any infections that fleas can transmit (such as lyme disease). It is a natural as well as effective way to stop the flea problem before they get inside and start an infestation. Highly recommend this product and will continue to keep using it!

The product came in a box with several freezer packs like it was suppose to, I put it out the next day and it rained for 3 days after I put it in my back yard, so I didn't have to wet my yard the first 3 days. I followed the direction on the package like I was suppose to but really couldn't tell a difference in the fleas in my yard or not because my dogs still had fleas. Around this same time frame I took my dogs to the vet and got a different flea medication and flea collar, so now I can't tell if they don't have fleas because of the vet trip or because I used this product. My back yard is all dirt under trees, when I walk in it I don't get fleas on me but they have got in my house before and we don't let our dogs come in side. Also I couldn't get ride of the fleas from my dogs no matter what we did, so maybe this product did work as my dogs are as flea-less as they can be to be outside dogs. I live in Florida where it's very hot with no humidity most of the year, ideal for fleas. https://www.amazon.com/dp/B00T80X348/ref=cm_cr_ryp_prd_ttl_sol_3 https://www.amazon.com/dp/B00T80X348/ref=cm_cr_ryp_prd_ttl_sol_3

Sigh. I received my package during a busy work day and put the package straight in the fridge so it would be ok. I set aside the small desiccant or whatever was in there. I've been struggling to figure out how to apply these; the pack was big and seemed full of some gel. This made so sense with the various instructions I have read. I've been loath to open it and try and get it into a sprayer as the little critters will start to die off I've read. I don't always clean up as well after myself as I ought. On my basement table where I'd left the 'desiccant' I suddenly realized this tiny package IS the nematodes. I've been hovering over a cold pack. LOL, yes I sound like an idiot. Still, be warned; this is a VERY small plastic baggie with a few grams of powder in it. Those are what you're after. Everything is so clear in hindsight.... My low rating is just to get by Amazon's requirements; these might work GREAT if you don't kill them... :)

First of all, the packaging was wonderful. I received my item quickly, on a hot day, and opening it immediately, I found the cooling packs packed with it still nice and cold. The directions were easy to understand, and I mixed and used the product that very evening. I had watered the yard before spraying, and watered slightly afterwards, then again for the next 3 days because it's warm and sunny right now, and I wanted my 50 million little guests to have a shot at surviving. This year's fleas are mutant super-survivors who have still managed to harass my dogs in spite of my using other flea control products conscientiously, including the monthly chewables plus the topical, from the vet, not the supermarket. I simply could not in good conscience add one more chemical to the mix, so this was my Hail Mary attempt, and I'm very happy. I believe it's working. I haven't actually trapped and counted fleas, but the big and most important proof that this product is working is that my dogs have stopped biting and scratching themselves silly! I plan to order more in a few weeks and give my yard another treatment, just to catch anything that might have escaped the first time. PS: I think the fly population has been decimated, as well.
