This means Bengal Gold provides longer-lasting control by preventing immature roaches from maturing into adults. Bengal Gold also has a more prolonged residual effect.

Active Ingredients

Bengal Roach Spray contains Permethrin as its sole active ingredient, which is a common synthetic pyrethroid insecticide. Permethrin quickly paralyzes the nervous systems of cockroaches and other insect pests, eventually leading to death.

Bengal Gold Roach Spray contains two active ingredients – Permethrin and Pyriproxyfen. The Permethrin provides fast knockdown, while the Pyriproxyfen is an insect growth regulator that prevents immature roaches from developing into adults so they cannot reproduce. This provides longer-term control.

Product Type

Both Bengal Roach Spray and Bengal Gold Roach Spray are insecticide sprays designed for indoor use to control roaches and other household pests like ants, spiders, silverfish etc.

They can be sprayed in cracks, crevices, along baseboards, under appliances, etc. Bengal Gold specifies it can also be used in attics.

Working Mechanism

Regular Bengal Roach Spray works through contact and ingestion. When roaches come in contact with or consume the Permethrin residue, it causes over-excitation of their nervous system, leading to convulsions, paralysis, and eventual death.

Bengal Gold’s dual active ingredients provide two methods of control. Permethrin paralyzes and kills roaches quickly when they come into contact with treated surfaces. The insect growth regulator Pyriproxyfen sterilizes adult roaches and interrupts the molting process, preventing immature cockroaches from developing into breeding, egg-laying adults.

Available Sizes

Bengal Roach Spray comes in 9 oz and 16 oz spray bottles for indoor application. The smaller 9 oz size is convenient for spot-treating smaller areas.

Bengal Gold Roach Spray only comes in one 11 oz spray bottle size for indoor use. The 11 oz size is suitable for treating medium to large rooms.

Pet Safe

The Bengal products are considered safe for pets once the treatment has dried completely on surfaces and any airborne spray has dissipated.

Bengal recommends keeping pets out of the treated area for 30 minutes after applying Roach Spray and 2 hours after applying carpet sprays.

Target Insects

Both products target roaches as well as other common household pests. Bengal Roach Spray claims to kill cockroaches, ants, beetles, centipedes, crickets, silverfish, spiders, and Asian lady beetles.

Bengal Gold Roach Spray has a slightly expanded list, targeting roaches, fleas, ticks, ants, mosquitoes, spiders, flies, gnats, and crickets. The Permethrin treats the wider variety of insects, while the Pyriproxyfen specifically targets roaches.

Insect Growth Regulation

A key difference is that Bengal Roach Spray does not contain any insect growth regulators. In contrast, Bengal Gold contains Pyriproxyfen, which sterilizes adult roaches and interrupts the life cycle of immature roaches.

Residual Action

Bengal Roach Spray works quickly but does not leave a lingering residue after initial application. Its residual effects decrease after a few days or weeks as the product degrades.

Bengal Gold Roach Spray contains an insect growth regulator that remains active on sprayed surfaces for up to 6 months, providing much longer residual control. The dual action keeps killing roaches initially and prevents new generations.

Odor & Staining

Both insecticide sprays claim to be odorless non-staining, and do not leave any visible residue after application. Users should not detect any chemical smell or see stains on treated surfaces.

Where to Apply

The products can both be applied in cracks and crevices, along edges, under sinks, stoves, refrigerators, baseboards, and other places where roaches hide. Bengal Gold can also be sprayed in attics for roof rat and bat control.


Both roach spray products come with a satisfaction guarantee or money-back promise if the customer is not happy with the results after following label directions. This provides confidence in effectiveness.

Our Observation
After reviewing the active ingredients and features of Bengal Roach Spray and Bengal Gold Roach Spray, we observe that Bengal Gold appears to be the superior product for long-lasting roach control.

Adding the insect growth regulator, Pyriproxyfen sets Bengal Gold apart by disrupting the roach life cycle and preventing immature roaches from reproducing. This provides up to 6 months of residual activity versus a few weeks for regular Bengal spray.

While both products deliver a quick knockdown, the dual-action of Bengal Gold offers more complete and extended protection against future infestations by inhibiting reproduction. The odorless formula is pet safe once dried, making Bengal Gold an excellent choice for whole-home roach treatment.
