Permethrin Insecticide, Nylar IGR Flea Sprays

Flea Elimination Kit for Indoors

Fleas are considered a general household pests, just as ants, roaches, silverfish and other bugs.  However, eliminating pests such as fleas, ticks, carpet beetles, often requires different techniques.  Pests in or on carpets, furniture and other delicate areas call for water-safe products.
When getting rid of indoor fleas, a combination of  insecticide and Insect Growth Regulator (IGR) is needed.  This combination takes care of 3 of the 4 stages of the flea population.

Indoor Flea Kit

Each Indoor Flea Kit contains:

  • 1 quart Permethrin SFR

  • 1 ounce Nylar IGR

  • Petcor Pet Flea Spray pint

  • Chapin pump type sprayer

Indoor Flea Kit Information, Ordering

Due to 1 ounce and 4 ounce IGR not being registered in many states, you may need to pick and choose products that can be shipped to you.
Products for getting rid of fleas can also be purchased individually.  When spraying indoors, always use products labeled for indoor flea control and always combine an IGR.

Indoor Flea Control

The first absolute “must” for an indoor flea job is to use products that are labeled for indoor flea use.  In order for an insecticide concentrate to be given an indoor flea label, it is tested for specific safety measures.  Once this type of product has been properly applied and treated surfaces have been allowed to dry, the treated areas must be safe for people and pets.  Professionals in charge of formulating, testing and marketing indoor flea products have extensive knowledge of various situations or environments where these pesticides are to be used.  For instance, they know that cats and dogs lay on these surfaces and that they groom themselves,  licking their paws and feet.  Small children crawl and play on these surfaces; small children also pick up many items off the floor and place them in their mouths.  All of these situations (as well as many others) are taken into consideration before an insecticide or IGR concentrate is given the all important “indoor flea label.”
The next “must” is that the material be water safe for fabrics in your home.  Exterminating fleas, ticks, bed bugs, carpet beetles and others requires spraying floors, carpets, rugs, furniture and other indoor items.  A “water safe” product will not stain a fabric that water does not stain.  If you an odd object in your home, you can first test a portion of the object to see if it stains or fades before applying your product.

Indoor Flea Control Products

When dealing with an indoor infestation of fleas, a combination of products should be used.  You need an insecticide and an insect growth regulator (IGR) used in together.  The products we suggest for use indoors have the important indoor broadcast label needed to safely do the job.  The insecticide kills adult fleas as they hatch; the IGR prevents all eggs and larvae from growing up or maturing into biting, jumping, reproducing adult fleas.
If you spray baseboards and cabinets with a professional insecticide, you can expect to have a residual action of about 4 weeks.  However, do not expect to see more than 2 weeks residual inside your home for adult flea populations found in your rugs, carpets or furniture.  For this reason, a second or follow up treatment is required for most flea infestations in homes.
The IGR used in this type of job does not need a second application, unless carpets are steam cleaned.  Under normal indoor circumstances, an IGR will last from 3 to 6 months.

When choosing products for an indoor flea problem, you will want to use an odorless or super low odor combination.  We have had great results using Permethrin SFR (concentrated professional strength Permethrin) or Onslaught insecticides; use NyGuard IGR or Nylar IGR with initial indoor spray treatment.
NyGuard works against more pests than any other IGR on the market:
More than 20 pests are listed on the NyGuard label, and that number will be increasing as field studies continue to come in.
Onslaught is a micro-encapsulated concentrate which yields an odorless solution; 1 ounce of concentrate per gallon of water is suggested for initial treatment for fleas.  Onslaught is an alternative insecticide to Permethrin.
The micro-encapsulated formulation gives a longer residual than regular concentrates.
(Onslaught is manufactured by the same company that invented NyGuard IGR.)

Our indoor flea kit contains 1 quart Permethrin SFR, a 1 ounce bottle of Nylar IGR, 1 pint of Petcor Flea Spray and a Chapin pump type garden sprayer.

Each 1 ounce bottle of Nylar IGR will cover up to 1,500 square feet of flooring and furniture.  If your home is larger than 1,500 square feet, order extra IGR so that your home is covered sufficiently.  The Petcor Flea Spray is for spraying dogs, cats, puppies, kittens and pet beds or resting areas.  Petcor contains natural pyrethrins and Methoprene.  The pyrethrins will give you a quick knock down of existing fleas on your pet.  Methoprene is an IGR that will inhibit the growth of flea eggs and flea larvae on and around your pets.
