Product Overview

Avesta CS Insecticide is a professionally formulated broad-spectrum microencapsulated insecticide that controls listed pests indoors and outdoors. It provides excellent control of insect pests including mosquitoes, ants, cockroaches, spiders, ticks, and flies (see label for complete list).  Containing Lambda-cyhalothrin, the same active ingredient as Demand CS Insecticide and Cyzmic CS, this controlled release insecticide provides a quick kill with a long residual.  

Avesta CS can be used to treat indoor areas and in cracks and crevices with low odor.  The microencapsulated formulation provides a long-lasting residual effect even in direct sunlight or other harsh conditions.

It can be applied outdoors in lawns, ornamental gardens, parks, and fields. Avesta CS is compatible to be tank-mixed with other registered pesticides and IGRs (Insect Growth Regulators).

How do I mix Avesta CS Insecticide?

Avesta CS is diluted with water before application.

Mixing steps:

  1. Fill the sprayer with the desired amount of water.
  2. Add the appropriate amount of Avesta CS.
  3. Close and shake the tank thoroughly.
  4. Re-agitate if spraying is interrupted.
  5. Mix only the amount needed for the treatment.
 

How do I apply Avesta CS Insecticide around my home?

For perimeter pest control, apply a continuous treatment band around the exterior of the structure.

Focus on:

  • Foundations
  • Doors and windows
  • Utility penetrations
  • Eaves and overhangs
  • Other potential pest entry points

For best results:

  • Remove leaf litter and debris near the foundation.
  • Trim vegetation touching the structure.
  • Move mulch and other pest harborage away from the home.
 

Can Avesta CS be used on lawns and turfgrass?

Yes. Avesta CS is labeled for lawn and turf applications to control surface-feeding, thatch-dwelling, and subsurface insects.

Common lawn pests controlled include:

  • Chinch bugs
  • Billbugs
  • Armyworms
  • Cutworms
  • Mole crickets
  • White grubs

Application rates and watering instructions vary by target pest.

 

Can Avesta CS be used for mosquito control?

Yes. Avesta CS can be applied to areas where mosquitoes rest and harbor.

Treatment areas include:

  • Landscape plantings
  • Turf areas
  • Building foundations
  • Exterior resting sites around structures

Regular treatments can help reduce mosquito activity around the property.

 

How long should I wait before rain after applying Avesta CS?

For maximum performance:

  • Apply when no rain is expected for at least 24 hours.
  • Allow treated surfaces to dry completely before rainfall occurs.
  • Do not apply during active rain events.

Once the application has dried, rainfall is unlikely to significantly reduce effectiveness.

 

Can I mix an IGR with Avesta CS Insecticide?

Yes, an IGR, like NyGuard can be tank mixed with Avesta CS.

Benefits of combining an insecticide with an insect growth regulator:

  • Kills existing adult insects
  • Prevents immature insects from developing into breeding adults
  • Improves long-term pest control results
  • Helps break the pest life cycle

This combination is commonly used for flea, cockroach, and other recurring pest treatments.

 

Does Avesta CS Insecticide have a strong odor?

No. Avesta CS is formulated with microencapsulation technology that provides effective pest control while maintaining a low odor profile.

Advantages include:

  • More comfortable applications around homes
  • Reduced noticeable chemical smell
  • Long-lasting residual performance
 

How long does Avesta CS last after application?

Avesta CS is designed to provide extended residual control on treated surfaces.

Residual performance can vary based on:

  • Target pest
  • Surface type
  • Weather conditions
  • Rainfall exposure
  • Frequency of cleaning or irrigation

Its microencapsulated formulation helps maintain effectiveness longer than many conventional liquid insecticides.

 

Should treated lawn areas be watered after an Avesta CS application?

Watering depends on the pest being treated.

For surface-feeding insects:

  • Delay watering for 12–24 hours after application.

For grubs and mole crickets:

  • Water in immediately with ¼–½ inch of water.

Always follow the label directions for your specific target pest.

 

Can Avesta CS be applied to ornamental plants and shrubs?

Yes. Avesta CS can be applied to ornamental landscape plants around structures where labeled pests are active.

Important restrictions:

  • Do not apply to edible crops.
  • Do not use on food-producing plants.
  • Follow all label directions regarding ornamentals and landscape applications.

    Control for Carpenter Bees

    By Shawn on 04/21/2023

    I used Avesta CS Insecticide to help control carpenter bees. The product works great! The bees have stopped coming to their existing holes and have not created new ones. I did also use Tempo 1% Dust to inject into the existing nests. The combination is a great one-two punch to prevent carpenter bees from continuing to nest and cause damage. After soaking the wood with Avesta CS Insecticide, I dusted the nests with Tempo 1% 12 to 24 hours later. 24 hours following the dusting, I then filled the holes with premium exterior wood filler. You can purchase cork or rubber plugs to fill the holes as well. The key is to make sure the bees are gone before filling the holes; otherwise, they'll either drill their way out through the existing filled hole or just create a new one. The combination of Avesta and Tempo work great together.

    Affordable alternative to Demand CS

    By Ian on 05/02/2023

    Had my own pest control company for a few years and Demand CS was my favorite repellent, the only downside was it's cost was significant compared to other products. We tried a couple of generic variants and they both had a strong odor and would agitate your lungs even with a N95 respirator. I sold the company a while back and still treat my home and the homes of a couple family members, I was going to order some Demand but saw Avesta with the same active ingredient and decided to order an 8 oz bottle to try. The product works fantastic and while it does have more of an odor than some other pesticides, it's actually a fairly pleasant one and does not cause any irritation. Fantastic product for personal or commercial use.

    works as well as Demand CS

    By Kurt on 07/08/2023

    I used Demand CS for years and usually had good results. I've switched to Avesta CS and am ordering my second quart now. Works as well as Demand and is much more cost effective.

    Doesn't work as well as Demand CS or Cyzmic CS

    By Kurt on 09/06/2024

    I know it's supposed to be essentially the same as Demand CS or Cyzmic CS but the results have not been the same for us. I can spray Demand CS and mosquitos in our yard are gone for at least a month. When I spray Avesta CS, there will still be a swarm around each person in the yard, within minutes, within a few days.
