Round Bromadiolone Wax Block Rodenticide Bait

⚠️ IMPORTANT SAFETY NOTICE: This product contains bromadiolone, a second-generation anticoagulant rodenticide. It is for professional use only. Apply only in tamper-resistant bait stations or in locations inaccessible to children, pets and non-target animals. Bromadiolone is toxic to aquatic life with long-lasting effects. Dead and moribund rodents must be searched for and removed during the baiting campaign.

GOLDEN-CAT Round Bromadiolone Wax Block Rodenticide Bait is a ready-to-use paraffin wax block with a central hole. The block is anchored on the rod of a tamper-resistant bait station so that it cannot be dragged out and consumed elsewhere. It is used in and around buildings, food processing facilities, warehouses, sewer-adjacent areas and agricultural structures.

The active ingredient is a second-generation anticoagulant with a delayed effect. The round shape and center hole are not decorative. They determine how the block is secured, how consumption is counted and whether the bait stays inside the station between service visits.

Product Specifications

The Center Hole and Carry-Away Behavior

Rodents do not always eat bait where it is placed. A rat or mouse that finds a loose block will often drag it into a wall void, under a pallet or into a burrow and consume it out of sight. When that happens, three things are lost at once. The applicator can no longer count consumption accurately, the bait is now outside the station and outside the control zone, and non-target animals may find it.

A round block with a center hole addresses this directly. The block is threaded onto the station rod or secured on the internal pin, so it stays in place while the rodent gnaws. A block that cannot be moved also cannot be cached, and the amount removed from the block face becomes a readable record of feeding activity at that station.

The round outline matters for a second reason. A block with a continuous edge presents gnawing surfaces around the entire circumference, not only at two or four corners. Where a square or rectangular block is only partly consumed, the round block tends to be worked from the rim inward, which makes the remaining volume easier to estimate at the next visit.

Station Compatibility and Anchoring

Round blocks are not interchangeable with rectangular blocks in every station. The center hole diameter and block thickness must match the station rod or pin, and a block that sits loosely on an undersized rod will still be displaced.

Where the station design uses a horizontal rod, the block sits like a wheel on an axle and can rotate as the rodent gnaws. Where the station uses a vertical pin, the block lies flat. Both are acceptable if the block is secure. A block that wobbles or lifts off the pin should be replaced with a weight and hole size that fit the station.

Mode of Action and the Delay Before Death

Bromadiolone blocks the enzyme that recycles vitamin K in the liver. With that step blocked, the liver cannot produce functional clotting factors and the blood loses its ability to clot.

The effect is not immediate. A rodent that has consumed a lethal dose continues to feed and move for several days before symptoms appear. Death usually follows within a week to ten days of ingestion, and animals often die in their burrow or nest rather than in the open.

Two operational consequences follow. A single feeding can be sufficient for control, because the rodent keeps feeding while the anticoagulant effect accumulates. And a rodent that dies above ground, or is consumed by a predator before it decomposes, creates a route for secondary exposure.

Secondary Poisoning Risk and Exposure Management

Bromadiolone can poison predators and scavengers that consume rodents carrying residues. The risk is a property of the active ingredient and it shapes the conditions under which the product is registered in most markets.

Keep placements within the distance limit stated on the batch label and away from ventilation duct openings. These limits define the zone in which the product is intended to act and outside which non-target exposure becomes harder to control.

Resistance and Treatment Failure

Resistance to anticoagulants is target-site based. It arises from changes in the enzyme that bromadiolone blocks, which reduce the enzyme sensitivity to the active ingredient. The practical significance depends on species and on the local rodent population.

An applicator cannot confirm resistance by observation alone. If a correctly placed, anchored and serviced campaign produces no reduction in activity, the first checks should be bait quality, station placement, competing food and under-baiting. If those are excluded and the site has a history of repeated bromadiolone use, resistance becomes a plausible explanation, and rotation to a different active ingredient is appropriate.

Wax Matrix and Damp Environments

The paraffin wax binder resists moisture penetration better than loose grain or pellet baits. That makes the round block more suitable for sewer-adjacent areas, loading docks, perimeter baiting and humid food processing environments.

Moisture resistance is not the same as suitability for standing water or submerged placement. A block that has been gnawed or cracked can still support mold growth on exposed surfaces. Inspect blocks during each service visit and replace any that have become caked, discolored, soft or covered in debris.

Wax blocks hold their shape longer than softer bait matrices, but they are not indestructible. A block that has been exposed to repeated freeze and thaw cycles may develop surface cracks. These do not necessarily make the block unusable, but they do increase the exposed surface area and should be noted during inspection.

Block Weight Selection

Intended Users

Licensed pest control operators, professional pest management companies, certified facility management teams, institutional pest control departments and agricultural pest control specialists.

Application Scenarios

Commercial and industrial buildings, food processing facilities, restaurants and food service areas, warehouses and loading docks, institutional buildings, agricultural structures, sewer-adjacent areas, damp voids and perimeter areas within the distance limits stated on the label. Residential multi-unit buildings may be treated only by licensed professionals and only in accordance with the label for that market.

Placement and Service Requirements

· Use tamper-resistant bait stations. Stations are mandatory for outdoor above-ground use and wherever children, pets, non-target mammals or birds may access the bait.

· Anchor the block on the station rod or pin. Do not place loose blocks inside the station or on the ground.

· Do not broadcast bait. Do not place bait near or inside ventilation duct openings.

· Record the number of blocks placed, the station locations and the condition of each block at every service visit.

· Replace blocks that have been consumed to less than about one third of their original weight, or that have become cracked, soft or covered in debris.

· Search for and remove dead or moribund rodents during the campaign. Wear waterproof gloves when handling carcasses or unused bait.

· Maintain a continuous bait supply for the period stated on the label, or until signs of new feeding cease.

· Follow the label for the batch supplied. Distance limits, station requirements and permitted use sites vary between registrations.

Compliance and Handling

· Read the product label before use. The label is the controlling document for permitted use sites, distance restrictions, station requirements and PPE.

· Wear waterproof gloves, long sleeves, long pants and shoes during handling. Wash hands thoroughly after handling and before eating, drinking or smoking.

· Do not eat, drink or smoke while handling the product.

· Store locked, in the original container, in a cool dry place inaccessible to children and separated from food, feed and water.

· Do not contaminate water, food or feed by storage or disposal. Dispose of unused product and empty containers according to local regulations.

· Do not reuse empty containers.

First Aid

· If swallowed: Call a poison control center or doctor immediately. Have the product container or label available. Do not induce vomiting unless instructed to do so by a poison control center or doctor.

· If on skin or clothing: Remove contaminated clothing. Rinse skin immediately with plenty of water for 15 to 20 minutes. Call a poison control center or doctor for treatment advice.

· If in eyes: Hold the eye open and rinse slowly and gently with water for 15 to 20 minutes. Remove contact lenses after the first 5 minutes, then continue rinsing. Call a poison control center or doctor for treatment advice.

· If inhaled: Move the person to fresh air. If symptoms persist, call a poison control center or doctor.

· Anticoagulant poisoning may require prolonged vitamin K1 therapy. Medical personnel should be informed that the product contains bromadiolone and that the anticoagulant effect can persist.

· Full first aid information is provided in the Safety Data Sheet.

Frequently Asked Questions

Why does the block have a center hole instead of being solid?

The hole allows the block to be threaded onto the station rod or pin so that it cannot be dragged out. A loose block is often carried into a void or burrow and consumed out of sight. When that happens the applicator loses the consumption record, the bait leaves the control zone and non-target exposure increases. Anchoring the block keeps it in the station and makes the remaining weight a usable record of feeding at that point.

Will the round block fit my existing bait stations?

Not always. The center hole diameter and block thickness must match the station rod or pin. A block that sits loosely on an undersized rod will still be displaced. Check three things before ordering: the hole diameter against the rod diameter, the internal height of the station so the block does not touch both floor and roof, and the entrance size so the target species can enter. Stations vary between manufacturers, so confirm fit rather than assuming compatibility.

How do I read consumption on a round block?

Inspect at each service visit and estimate the proportion of the block that has been removed, from the rim inward. A block that has been consumed to less than about one third of its original weight should be replaced. A block that shows no gnawing marks after a period in which activity was confirmed nearby should be relocated rather than left in place indefinitely. Record the condition of each block, not only the number placed, because the pattern of consumption across stations is more useful than a single total.

Can the block be broken for mouse placements?

Only where the label for the batch supplied permits it. Breaking should be done while wearing waterproof gloves and over a contained surface so that fragments are not scattered. A broken round block can no longer be anchored on the rod, so fragments must be secured inside the station by other means or the advantage of the center hole is lost. For mouse work, a 15 g block may be a better fit than a broken larger block.

How would an applicator know whether resistance is the cause of a failed treatment?

Resistance cannot be confirmed by observation alone. If a correctly placed, anchored and serviced campaign produces no reduction in activity, check bait quality, station placement, competing food and under-baiting first. If those are excluded and the site has a history of repeated bromadiolone use, resistance becomes a plausible explanation. Rotation to a different active ingredient is then appropriate, based on treatment history and inspection findings rather than a fixed calendar.

What documentation is supplied with an order?

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, storage and disposal. The COA documents active ingredient content for the batch supplied. These documents support the buyer hazard communication and quality records. They do not replace the requirement to verify local registration or import eligibility.

Do you offer private label or custom block weights and hole sizes?

Yes. OEM and ODM are available for professional distributors and brand owners. Custom block weights, center hole diameters, colors and packaging formats can be discussed against minimum order quantities. Hole diameter is a functional specification, so confirm the intended station model before placing a custom order. Private label does not transfer the buyer responsibility to ensure that the label and claims used in the destination market are compliant with local regulatory requirements, including bait station and distance restrictions.
