LambdaStar 9.7% CS Insecticide
  • Alternate Image 1

The LambdaStar 9.7% CS Insecticide provides optimal insect control that is ideal for indoor and outdoor applications. This insecticide is a microencapsulated lambda-cyhalothrin that features an easy to mix formula and makes use of the advanced EcoCap technology. Its EcoCap utilizes vegetable oil instead of petroleum products for an environmentally safe and long-lasting 90 day residual. LambdaStar effectively targets ants, bedbugs, bees, centipedes, cockroaches, flies, mosquitoes, spiders, brown marmorated stink bugs, kudzu bugs and more. The product is perfect to apply in, on and around buildings and structures, including on lawns, ornamental shrubs and trees around residential, commercial, agricultural, industrial institutional and public buildings. Also, the insecticide can be also utilized in parks, recreational areas and athletic fields.


LAMBDASTAR 9.7% CS is for use as a general surface (nonfood/nonfeed areas), crack and crevice, or spot treatment in, on, and around buildings and structures and their immediate surroundings, and on modes of transport. Areas of use include, industrial buildings, houses, apartment buildings, laboratories, buses, greenhouses (non-commercial), stores, warehouses, vessels, railcars, trucks, trailers, aircraft (cargo and other non-cabin areas only), schools, nursing homes, hospitals, restaurants, hotels, livestock/poultry housing, pet kennels, food granaries, food grain mills and food manufacturing, processing, and servicing establishments.

Nonfood/nonfeed areas of food/feed handling establishments include garbage rooms, lavatories, floor drains (to sewers), entries and vestibules, offices, locker rooms, machine rooms, boiler rooms, garages, mop closets, and storage (after canning or bottling).

For indoor applications, LAMBDASTAR 9.7% CS can be reapplied at 21-day intervals if necessary.

    5 of 5 stars  It just works!
    By Gordon in Menifee CA on 08/16/2015

    I have a 2100 sf single story home. We moved in almost a year ago and started having serious spider issue along with all the other bugs, earwigs etc. I used 3 gallons in a back pack sprayer and did a 3 foot up and 3 foot out aplication around the perimeter of my home and under all the eaves. The next day we had dead bugs everywhere inside and out. It's now been two weeks and have not seen one live bug in the house. This stuff is the real thing!

  • 5 of 5 stars  Long lasting and effective
    By David in Lakeland FL on 02/17/2017
    Verified Purchase

    Large population of Earwigs after about a year in a new construction home. No professional pest service ever done. Filled a 4 gallon backpack sprayer, did a 3 foot band up the walls and into the lawn, shrubs. Also around all windows and doors. Inside under fridge, stove, baseboards around toilets, under sinks where the drains go behind cabinets. Sprayed 1st time 15 months ago,which really knocked back the population, and again 12 months ago. No bugs. Just starting to see a couple on the patio, so its time to make the annual rounds. At this rate, the product will last another few years.

QIs lambdastar 9.7 safe around children and pets when on the grass?
I am looking for something to control the bugs this summer an have a pet who likes to eat grass, and kids who play in the grass. I just want to make sure it is safe before using it.

AOnce the Lambdastar 9.7 has dried completely after spraying then it is completely safe for children and pets.

QHow effective is LambdaStar 9.7 % on mosquitoes?
We live on 30 acres with swamp in front and behind where our house sits. Would this be the best choice for a perimeter spray to stop them from getting to our living space? How often should we treat?


LambdaStar 9.7 is a great insecticide for all sorts of pests including mosquitoes around the home. Our top product however for mosquito control is Talstar P which we recommend the most and is also a little more cost effective. You can look over our Mosquito Control Guide to see all the different steps and products to use to effectively get rid of mosquitoes around your home.†
