LambdaStar UltraCap 9.7%

LambdaStar UltraCap 9.7% consist of a capsule suspension formulation of lambda-cyhalothrin which features extended residual protection. Microencapsulation is a process that helps the pesticide to stick to the applied surface, making it very effective at long term pest control. Keep the solution suspended by shaking it before spraying LamdaStar UltraCap. Do not allow the product to enter any drain during or after application. 

It is for outdoors including structural, turf and ornamental, and livestock housing as well as indoors in food areas. Mosquito treatment is ideal with this due to the powerful knockdown and extended residual activity. It will even work on hard-to-control species such as scorpions. Common uses for this includes: treating the area around a structure, spraying on lawns and other vegetation, creating a barrier on the side of a building, under doors, eaves and windows that are protected from rainfall, and any problem entry points that pests could go through. Can be used in food areas by only the crack and crevice and spot treatment methods. Other pesticides or Insect Growth Regulators may be used with LamdaStar Ultracap.

Registration in California is currently pending.

Premise Perimeter Barrier Treatments Apply a continual band of insecticide around building foundations and around windows, doors, service line entrances, eaves, vents, and other areas to reduce the potential for entry by crawling pests. Before application, remove debris and leaf litter from next to the foundation, cut back vegetation and branches that touch the foundation, and move or rake back rocks, deep mulch, or other potential pest harborage next to the foundation. Apply the band up to 10 ft. wide around the structure (or according to state regulations governing commercial pest control) and upwards along the foundation to 3 ft. and around windows, doors, and roof overhangs. Apply as a coarse spray to thoroughly and uniformly wet the foundation and/or band area so that the insecticide will reach the soil or thatch level where pests may be active. Amount of concentrate is dependent upon pest species (see pest table and comments), infestation levels, and service interval desired.

    4 of 5 stars  So far, so good.
    By David in Rifle CO on 09/09/2015

    I just applied the spray a week ago for spiders and sow bugs invading the house so I am not sure on it's long term effectiveness. So far, in the short term, it is working well, you can tell by the band of dead bugs that must be swept away each morning surrounding the house. I used a slightly higher mix the first time, .08 instead of the .04 recommended for the initial application, it was pretty bad. I think with this stuff I will finally gain the upper hand on the bug situation.

    By Jc in Charlotte, NC on 04/01/2016

    Sprayed this at the beginning of the carpenter bee season and will reapply today. I have not seen one bee since application. Last year I had 50 bees circling my house destroying the painted wood surfaces. Not this year!

    Purchased LamdaStar UltraCap 9.7% for minimal (or so I thought) roach problem. Sprayed this around bottom foundation of the house. By the time I came back around, there were roaches scurrying around. Surprise!!! This stuff is great. Good recommendation and instructions for this product supplied by DoMyOwnPestControl.

QIs LambaStar UltraCap 9.7% the best for scorpions?
We are in hot Arizona weather with a block fence. What product is best for scorpions, LambdaStar, Cy-Kick, or Onslaught FastCap?


All the products that you have listed are great choices for scorpion control in the heat because they are all micro-encapsulated and will, therefore, hold up better in the heat. LambdaStar UltraCap 9.7% is fairly economical since it is used at a rate of 0.8 ounces per gallon of water for scorpion control. CyKick CS is our most popular concentrate for scorpion control. Onslaught FastCap differs in that it contains an extra active ingredient for faster initial kill when applied. This insecticide also covers and extremely broad list of pests on the product label. Please see our Scorpion Control Page for more information and tips about treating for scorpions.

QIs LambdaStar UltraCap 9.7% a good choice for cockroaches, millipedes, centipedes, and assorted spiders?
Just moved to Big Island of Hawaii; hoping shipping is reasonable.


There are a variety of great options for general pest control for you. A great choice would be LambdaStar UltraCap 9.7, which is micro-encapsulated for long residual in the heat, sun, and rain. Use 0.2-0.8 fl. oz. per gallon of water as a perimeter treatment and as a spot or crack and crevice spray indoors. Most of our customers in Hawaii choose shipping via Priority Mail, which is typically very reasonable for small packages such as insecticides. You can check shipping rates by adding items to your shopping cart and then entering your zip code.

QScorpion control in Phoenix
For outside use, spraying around house foundation etc, how often do I have to re spray?

ALambdaStar UltraCap 9.7% is labeled for scorpions. You will use 0.8 fl. oz. per gallon of water. Make sure to spray in areas where you have seen them and around the perimeter of your home. Also spray in areas where they could possibly come indoors, such as around doors frames and windows. If you are spraying outdoors, you will need to spray every 21-30 days. If you are spraying indoors, you can spray every 90 days.

05/12/2016 Earwighater from Descanso

QIs LambdaStar UltraCap 9.7% the best spray to kill and keep earwigs out and away from our home?
Earwig infestation outside of our country house and they are coming in and all over the place. We kill them all day in the house and there a a gazillion outside of the house. We live in the country on natural land. We are on a well and don't like to use chemicals unless necessary. You pick anything up in the house and under it lies an earwig.


LambdaStar UltraCap 9.7% is labeled for earwigs. I would recommend that you use Onslaught FastCap Spider and Scorpion Insecticide  as well as Trapper LTD Mouse/Insect Glue Boards to help trap them indoors. The Onslaught would give you complete control both indoors and out as well as be odorless and non-staining. Be sure to use this product no less than 5 feet from your well as well. Earwigs prefer moist, dense soil where there is plenty of organic buildup to feed them, so looking for ways to help soil air out - such as turning the soil and removing excess covering like mulch or pine straw - will also make those areas less attractive to the earwigs.
