⚠️ IMPORTANT SAFETY NOTICE: This product contains 2.5% imidacloprid. Read the label before use. Keep out of reach of children and pets. Wash hands after handling. Imidacloprid is toxic to bees. This product is formulated for structural cockroach control and is not intended for outdoor agricultural or foliar use.
GOLDEN-CAT 2.5% Imidacloprid Cockroach Gel Bait Gel is a ready-to-use gel bait supplied in a syringe with a narrow applicator tip. It is intended for placement of small gel deposits into cracks, crevices and confirmed harborages in structural cockroach management programs.
Gel bait performance is determined less by the product alone than by how it is placed. Imidacloprid must be consumed in sufficient quantity to deliver a lethal dose, and the deposit must remain palatable long enough for cockroaches to encounter it during normal foraging. Two variables fall under the applicator’s control: deposit size and location relative to active harborages. Both are governed by label application rates and by inspection findings rather than by product choice alone.

Published EPA-registered gel bait labels and EU authorization documents converge on a consistent principle: numerous smaller deposits provide faster control than fewer larger deposits. The reason is encounter probability. A cockroach foraging along a crack line is more likely to encounter several small deposits distributed along its path than a single large deposit placed at one point.
| Parameter | Reference point |
| Deposit weight per point | EPA bait quantity reference: a spot of approximately 1/4 inch diameter corresponds to roughly 0.1 g of gel. EU authorization documents for a comparable gel bait reference spots of 4 mm diameter at approximately 0.032 g, and 5 mm spots at approximately 0.05 g. |
| Maintenance and low infestation | EPA label for small cockroach species: 0.75 g per square yard for maintenance programs; up to 1.5 g per square yard for light to moderate infestations. EU reference: 1 to 2 spots of approximately 0.032 g per square meter at low infestation. |
| Moderate infestation | EU reference: 3 to 6 spots of approximately 0.032 g per square meter. |
| Heavy infestation | EPA label: up to 3.0 g per square yard for severe infestations. EU reference: 6 to 10 spots of approximately 0.032 g per square meter. |
| Large cockroach species | EPA label for American, smokybrown and Oriental cockroach: 1 to 2 g per square yard. |
| Interval between points | Place at or near harborages, corners and crack lines. Numerous small placements at close intervals are preferred over wide spacing of larger deposits. Exact spacing depends on harborage density and inspection findings, not on a fixed rule. |
These figures are starting references for professional judgment. The applicable label for the batch supplied remains the controlling document for application rate in the destination market.
Gel bait adheres poorly to greasy or dusty surfaces, runs on hot surfaces, and loses acceptance if applied adjacent to repellent insecticide residues. EPA label restrictions for gel baits in food handling establishments provide specific thresholds that are useful beyond that setting as general application criteria.
| Condition | Practical implication |
| Surface temperature above approximately 54°C (130°F) | Gel may run. Examples include portions of stoves, ovens, grills, fume hoods and heat lamps. Avoid these surfaces regardless of setting. |
| Routinely washed surfaces | Bait will be removed by washing before it can act. Do not place deposits on surfaces subject to routine cleaning. |
| Recently sprayed surfaces | Repellent residues reduce bait acceptance. Do not apply gel bait to areas sprayed with a repellent insecticide, and do not spray over existing gel deposits. |
| Greasy or dusty surfaces | Gel may not adhere. Clean or skip the surface; a deposit that falls away cannot be consumed. |
The four species covered by this product differ in size and preferred microhabitat. Placement decisions that suit German cockroach do not transfer directly to American or Oriental cockroach.
| Species | Adult body length, approx. | Placement note |
| Blattella germanica (German) | 10 to 16 mm | Harbors in tight cracks near warmth and moisture. Deposits should be small and placed inside the crack line, not on adjacent exposed surfaces. |
| Periplaneta americana (American) | 28 to 44 mm | Often associated with floor drains, basements and sewer-connected areas. Larger species require higher bait quantity per area, as reflected in the EPA rate table. |
| Blatta orientalis (Oriental) | 20 to 27 mm | Prefers cooler, damp locations. Gel may absorb moisture or lose adhesion in persistently damp voids; inspect more frequently. |
| Supella longipalpa (Brown-banded) | 10 to 15 mm | Often harbors higher in rooms than German cockroach, including picture rails and furniture undersides. Placement should include elevated locations. |

Imidacloprid is toxic to bees and other pollinating insects. This product is formulated for structural cockroach control. It is not intended for outdoor agricultural, ornamental or foliar use. In several jurisdictions, neonicotinoid restrictions apply specifically to outdoor ornamental or agricultural applications while structural pest control uses are addressed separately. Applicators and buyers must confirm the registration status of the specific product in the destination market before import or use. The label for the batch supplied governs the permitted use sites.

EPA bait quantity references give approximately 0.1 g for a spot of 1/4 inch diameter, and EU authorization documents for comparable gel baits reference 4 mm spots at approximately 0.032 g. At low infestation, 1 to 2 spots per square meter are referenced; at high infestation, 6 to 10 spots per square meter. The EPA label for small cockroach species gives 0.75 g per square yard for maintenance programs, up to 1.5 g per square yard for light to moderate infestations and up to 3.0 g per square yard for severe infestations. The principle behind these figures is that encounter probability increases with the number of small deposits, not with the size of individual deposits. Confirm the exact rate on the label of the batch supplied.
Imidacloprid bait relies on ingestion and secondary transfer. It does not deposit a residual film that kills on contact. This means efficacy depends on placement accuracy and continued palatability. A spray may kill cockroaches that contact treated surfaces, but it can also leave repellent residues that reduce bait acceptance if the two are used in the same area without an interval. If a spray has been applied, allow the surface to dry and, where label directions permit, wait before placing gel bait in or adjacent to that area.
The first explanations to investigate are placement and acceptance, not active ingredient failure. Check whether deposits are still present and palatable, whether they were placed inside confirmed harborages, whether the surface was greasy or hot, and whether a repellent spray was applied nearby. If those factors are excluded and the site has a history of repeated imidacloprid bait use, reduced susceptibility becomes a plausible factor. Published field data show that imidacloprid bait performance indices vary widely across populations, and a multi-formulation comparison found the imidacloprid formulation to have the lowest efficacy among the gel baits tested against certain pyrethroid-resistant field populations. Rotation to a bait with a different mode of action is a recognized resistance management practice, but the decision should be based on treatment history and monitoring data, not on a fixed schedule.
Use in food handling areas is governed by the label in the destination market and by applicable food safety regulations. The formulation is intended for crack-and-crevice placement, not for application to food contact surfaces or to areas where food is exposed. EPA label restrictions for gel baits in food handling establishments limit application to crack and crevice treatment and prohibit application to surfaces that are routinely washed, because the bait would be removed before it can act. The buyer or applicator is responsible for confirming that the intended placement is consistent with the local label and the facility food safety plan.
Each shipment is accompanied by a Safety Data Sheet and a Certificate of Analysis for the batch. The SDS covers hazard identification, first aid, handling and storage, and disposal. The COA documents active ingredient content and relevant quality parameters for the batch supplied. These documents support the buyer internal hazard communication and quality records. They do not replace the requirement to verify local registration or import eligibility for the active ingredient.
Deposits remain attractive and effective for a period that depends on temperature, humidity, surface condition and pest pressure. Inspect at 7 to 14 day intervals during active treatment. Replenish deposits that have been consumed. Remove and replace deposits that have dried, hardened or become coated with grease or dust. Replace bait before it is completely consumed, so that cockroaches continue to encounter it rather than finding only empty points. A visual inspection one month after initial treatment is a commonly referenced checkpoint.
Yes, and the restrictions vary by jurisdiction. Some jurisdictions regulate neonicotinoids specifically for outdoor ornamental or agricultural uses while treating structural pest control use separately; others have broader restrictions. The applicable label for the batch supplied is the controlling document for permitted use sites in the destination market. Buyers are responsible for verifying that the intended import and use of the product is permitted under the regulations that apply at the destination.
Yes. OEM and ODM are available for professional pest control distributors and brand owners. Custom syringe fill sizes, labeling and packaging formats can be discussed against minimum order quantities. Private label does not alter the buyer responsibility to ensure that the label and claims used in the destination market are compliant with local regulatory requirements.
