How FenvaStar EcoCap Works

FenvaStar EcoCap is a liquid insecticide concentrate with the active ingredient Esfenvalerate. Esfenvalerate is a synthetic pyrethroid, a man-made insecticide created to mimic the chemical properties of naturally occurring pyrethrins. FenvaStar EcoCap also has the advantage of microencapsulation, meaning the product is a concentrated suspension with millions of tiny capsules containing the active ingredient. When insects come into contact with the spray or residual left from applying FenvaStar EcoCap, they pick up the tiny capsules on the hairs on their legs and bodies, and the esfenvalerate attacks the central nervous system of the insects, causing paralysis and eventual death.

Target Uses of FenvaStar EcoCap

FenvaStar EcoCap is an excellent choice for general, broad-spectrum insect control as a perimeter barrier outdoors and crack and crevice or spot treatment indoors. FenvaStar EcoCap has low odor and no VOCs, making it ideal for more sensitive accounts and situations where multiple treatments may need to be made, such as for bedbugs. Microencapsulation makes FenvaStar EcoCap a great choice to treat flying pests such as mosquitoes or carpenter bees, or for use in areas exposed to direct sunlight. FenvaStar EcoCap is also labeled for use for many common livestock pests and plant pests. With its broad list of target pests and usage sites, FenvaStar EcoCap eliminates the need for multiple products for a variety of jobs.

ACTIVE INGREDIENT: Esfenvalerate 3.5%

FenvaStar EcoCap Application Instructions

Shake well before using. When mixing, add approximately half the required water to spray tank and then add appropriate amount of concentrate. Agitate and slowly add the remaining water. Agitate spray thoroughly before using and also occasionally during use to ensure dispersion. Use 1-2 ounces of concentrate per gallon of water and apply with a hand pump sprayer. Apply 2-second bursts of spray per square foot of area being treated. Avoid excessive application. Dampen surfaces but not to the point of saturation or run-off. Repeat applications as needed, but do not exceed more than one application every seven days (most applications; do not exceed more than one application every 14 days in food handling establishments).


* Always read the product label completely before use.

  • An 8 ounce bottle yields 4-8 gallons of finished solution.
  • One gallon (128 oz.) bottle yields 64-128 gallons of finished solution.

Standard Application Dilution rates / Mixing Ratios for FenvaStar EcoCap:

  • 1 fl. oz. (30mL)/gal. of water – 0.025% - general use, maintenance, prevention.
  • 2 fl. oz. (60mL)/gal. of water – 0.05% - heavy infestations, initial clean out; stinging insects.
  • 0.2-2.0 fl. oz./gal. of water or in sufficient water to cover 1,000 sq. ft. – broadcast or foliar spray of ornamental trees, landscapes, lawns, and turf.

1 gallon of finished solution typically covers 1,000 square feet. Higher volume applications may be used for outdoor treatments such as broadcast lawn treatments or foliar applications in mosquito breeding sites. See product label for complete instructions for outdoor applications.

To help prevent insect infestation of buildings, treat a 2-6 food band of soil or other substrate adjacent to buildings. Treat building foundation to a height of 2-3 feet. Treat exterior walls, eaves, cracks and crevices, and other areas where pests are active and may find entrance into the building. Alternate mixing directions are to use 4-8 fl. oz. of concentrate per 50 gallons of water.

Use lower rate range for turf pests that are commonly exposed and will be contacted by spray solution at the time of application. For pests that will not be contacted by spray solution at the time of application, use the upper rate range. Use 2 fl. oz. per 1,000 sq. ft. when treating mole crickets and chinch bugs.

    5 of 5 stars  Promising product!
    By Bughater in Fairfax, VA on 10/23/2012
    Verified Purchase

    I purchased this item to get rid of bed bugs, I can not report on long term use, because I just used it yesterday but I can tell you it works and it works fast. It has no odor, I used it with gallon sprayer as recommended and I added Gentrol IGR into the mix, since this was my first time application I used 2 fluid ounce instead of 1 fluid ounce to prevent re infestation of bedbugs. After a mix , fluid is milky color but it dries clear without leaving any stains. By the time I ordered this product I am confident I had already eliminated at least all adult ones using a steam cleaner (almost everyday) for past six weeks, DE, 90% alcohol, Clorox, Bedlam Plus, and combination of Essential Oils in steamer such as Clove oil, Pepermint, Orange oil, Rosemary and Cedar oil. I put 10 drops of each to 32 ounce water, I than add 1 fluid ounce of this mixture to the water that I put in the steamer. Not only vapor alone kills the baby ones readily, the steam comes out dryer with more pressure force than when used water alone. I live in a condominium where the whole complex has bed bug problems, there for I have no choice but keep using products such as this one to prevent re- infestation. The reason I say this about a week ago while I was steam cleaning my carpets I lifted the clear plastic mat that was under the front entrance door, I discovered 5 adult dead bedbugs that got stuck between the carpet and the mat! I than realized they are coming just like everyone else, from the front door. After I sprayed along the base boards and cracks even the kitchen with FenvaStar, I sprayed front of my door and the hall way and front of neighbors door while no one was looking. About 20 minutes later when I walked in to my kitchen I saw 2 adult dead roach on the floor that I didn't even know that I had. The next day (which is today) my neighbors knocked on the door to show me the dead adult bedbugs that they found right along where I sprayed. So I can tell you this product works and I hope it will keep on working. From an experience one more thing I have to add, when you treat the infested area such as your mattress or couch, if you do not treat the carpet underneath at the same time, you are guaranteed to get re infestation, you have to steam it the way you steam your mattress and steam wash your whole carpet as soon as possible. The young bedbugs hide inside the carpet, you can't see them, but you will see them in your dirty water when cleaning your carpets. When washing clothes use Clorox and add cup of distilled vinegar to rinse water to kill all eggs, also add vinegar while steam cleaning carpets. Bed bugs are very psychologically draining, and depressing, I agree with most reviews on this site you have to use combination of products, I doubt if one product alone will get rid of them. This one works and reasonably priced!

    5 of 5 stars  Updating: Promise delivered!
    By Nurten on 10/28/2012
    Verified Purchase

    Five days after the first application, I started wondering how come I can't even see just one bed bug, I know I have eliminated the adult ones but every evening I go around the infested part of the apartment with a magnifier glass and able to find the colorless little ones, before steaming them.(By the way not all colorless ones can be seen with a naked eye, they may appear as little as salt grain, but they move!) I had only used this product only along the base boards cracks and crevices and only very lightly wood part of the under the sofa and box mattress, being careful not saturating the fabric (while I was putting it I was not sure if it was going to stain or not at the time). This morning I turned over my sofa, (which is the most infested part in the apartment) I found over dozen bright red dead bed bugs along the wood casing, I would say they were the size of ranging from 2nd 3rd and 4th in star nymph,( I collected few and looked at them with a magnifier), very strangely, out of all the places, I also found few on the carpet that is front of the Bathroom, I had been seeing them while I was vacuuming but I had dismissed them as red lint from the towel. After finding the ones under the sofa, I again found some in that area and looked again , yes they were dead bed bugs. I did not use vinegar while steam washing that part of the carpet because I had ran out of vinegar, I will definitely go get another gallon and steam wash that part again. There you go, this product once again earned my FULL SEAL OF APPROVAL and I approve this massage!

    5 of 5 stars  A professional Review
    By M. in Arizona on 12/13/2013
    Verified Purchase

    I worked in Commercial Pest control for many years. There are many good products on the market but I have chosen FenvaStar EcoCap as the product to treat my home. It's very flexible. For general maintenance I use 1 ounce per gallon. For the busier "bug season" I bump it to 2 ounces per gallon. It's encapsulated which means it's easier for the insect to get a lethal dose on him. It's so easy to treat your own home! Get a sprayer, gloves and eye protection and DO IT YOURSELF! Working for people like ORKIN pest control left a bad taste in my mouth for the pest control industry in general. They view customers as cattle with purses. Everything they use you can buy here and save a ton of money. This product works! It's in a small container so you'll be able to use it up before it goes bad. Read the label and DO IT YOURSELF! :-)

    5 of 5 stars  Great Bed Bug Defense in Public Hallway
    By Jade in Chicago on 03/05/2013

    All right, I have written about the wonders and joy of BedLam on the inside of my apartment to rid me of bedbugs, but FenvaStar EcoCap mixed with Gentrol is my secret weapon against re-infestation from my bug bombing infested neighbors next door on both sides of my apartment. I am in Chicago, and we are having major bed bug issues. In my building, we didn't get infested until 2 months ago and all of the neighbors on our side of the floor were getting bites. Needless to say, the new people that moved in 3 months ago moved in infested. But instead of contacting the building, they bug bomb each weekend and boy can you tell. Every weekend, around sunday night, the bed bugs start showing up on the walls in the hallway and under my door, and there I am on Sunday night spraying....and vacumming the pile of carnage by Monday morning. So after talking to my manager, getting quotes, they said they can't do anything unless they call to have them spray and they haven't called. Now imagine one neighbor on one side bombing and the other neighbor on the other side doing nothing...bed bugs coming in through the pipes. In comes FenvaStar EcoCap and Gentrol and my beloved plant pump sprayer. Sprayed my perimeter, under the sink, my whole front door, around the front door and in the corners of the wall. Took it one step further, snuck out at 2am to the hallway and sprayed my neighbors door on both sides, the perimeter and the hallway walls. Now I still hear my neighbors stomping and vaccumming but no more bugs in the hallway or in my bathroom sink, and barely anything under my front door..I just re-spray every 2 weeks. I finally let my manager in on what I was doing, and he loved it and is now recommending gentrol to his pest control company that sprays. Whew! But to this day, the neighbors haven't been treated so I'll be a loyal customer till somthing knocks these bedbugs out! Thanks! :)

    It is very important to note that bedbug treatments typically take several applications over several weeks. It is recommended that you use more than one product to overcome the chance of the bedbugs developing resistance to the product you are using. Please take a few moments to read over our Bedbug Guide.

QCan I use FenvaStar to treat the carpet for bed bug nymphs?
I'm currently living in an apartment complex and both apartments next to mine to the right and left of me are infested. The tenants are bug bombing and they are now coming through the drain pipes and fenvastar is working great to kill them there. I did a perimeter spray with FenvaStar, but I want to know if I can also treat the carpet? Not saturating it of couse due to the water but a light misting?

AThere really is no need to treat the whole carpet with Fenvastar for bedbugs. If the bedbugs do move through the walls into your apartment they will pass through the product that you applied around the perimeter and be killed. If you feel you must spray the carpets Fenvastar is labeled to be used as a broadcast spray over carpeted areas.

QWill Fenvastar EcoCap kill the Bougainvillea Looper in Southern California?
Does anyone have experience with using this product to control loopers- especially bougainvillea loopers? Is there another product that would be better? If we apply FenvaStar, should it be mixed with an IGR for this application? We have had limited success with applying imidacloprid both as a leaf spray and as a soil application. BT and Spinosad have not worked either.


We typically recommend Spinosad for looper control as it is highly effective against the adults and young larvae Customers have had great success when plants are treated as needed with the adequate amount of coverage. However, Fenvastar EcoCap is labeled for looper control as well but unfortunately, we have not heard any feedback from customers using Fenvastar Eco Cap on Bougainvillea to control loopers and we are also not aware of any IGR on the market that is labeled for loopers. Be sure to read and follow the label instructions and if we can help further please let us know.

QWill Fenvastar EcoCap kill moths?
I've tried traps, and they have not eradicated the product


Yes, Fenvastar EcoCap is labeled for moths. This is a crack, crevice and baseboard spray. You will use 1 fl. oz. per gallon of water. This can be used every 90 days indoors.

Also, it is important to know when using traps for moths, you will need to make sure you are only using two total traps in your home at a time. If you are using more than two traps at a time, the moths become confused and do not enter the traps.

AYou do not need a license when applying Fenvastar EcoCap to your own home but any application of insecticides done to anothers property for profit does require you to have a license through your state.

QCould I use FenvaStar EcoCap instead of Onslaught for baiting Yellow Jackets ?
It uses the same active ingredient, although at a lower concentration. I'm thinking since FenvaStar doesn't use pretroleum carrier it may be less likely to cause rejection of the bait. And should mix well with water based baits.

AYes, per the product label the Fenvastar EcoCap can be used mixed with foods for baiting yellow jackets and other stinging insects.

QCan you spray plum trees with FenvaStar EcoCap

AFenvaStar EcoCap cannot be applie to edible vegetation. What exactly are you treating for? Depending on what you are treating for, you can use Malathion on Plum Trees.  You should apply at a rate of 2 tablespoons per gallon of water.  Typically Malathion will last for 30 days before it needs to be re-applied.  You should not apply this product within 2 weeks of harvesting.

QCan I spray FenvaStar on pantry shelves to help control Indian meal moths?

AFenvaStar EcoCap is labeled to be applied to cracks and crevices including cabinets. We do recommend that you clean out all the food that could potientially contain larvae, wipe down the cabinets with hot soapy water and apply a crack and crevice application for treatment. We also carry ProPest Traps that will impede the life cycle by trapping the adult males.
