Roach Control for Multi-Unit Buildings: A Landlord Treatment Plan
Treating one flat in a connected block fails predictably. How to survey across unit boundaries, quantify a build...

For pet owners, treating a home pest infestation requires balancing effectiveness with the safety of curious cats and dogs. Standard chemical liquid sprays and open, sticky gel baits pose a continuous poisoning risk, as pets can lick treated surfaces or chew on exposed plastic traps. If there are cats or dogs in the home, our pet-safe roach killer guide walks through which product formats are safe to use around them.
Dogs and cats navigate the home close to the floor, sniffing and licking along baseboards and cabinet bottoms where sprays are applied. This grooming behavior can lead to accidental ingestion of toxic chemical residues, resulting in veterinary emergencies. Furthermore, standard insect gels contain sweet active compounds that are highly attractive to domestic animals.
To protect your pets while ensuring complete, high-performance pest elimination, the RoachBuster dry paper sachet system provides an elite, safe alternative:
Most placement advice is written as if a home were a floor plan. For a pet owner it is more useful to think of the home as a set of animal routes. A cat has vertical access to almost everything, including worktops, the top of the fridge and the gap behind a wall-mounted cupboard, but very little interest in enclosed low cavities. A dog has the opposite profile: no vertical reach, but strong interest in floor-level cavities, food smells and anything that can be nosed out from under an appliance. A placement that is safe from a cat may be exactly the wrong choice for a labrador, and the reverse is also true.
So the first job is to walk the home twice, once at cat height and once at dog height, and mark which cavities each animal can actually get into. That takes ten minutes and it decides your whole plan.
| Position | Cat access | Dog access | Verdict |
|---|---|---|---|
| Inside under-sink cabinet with a working catch | No | No | Best position in the house |
| Behind the fridge in the compressor recess | Rarely | No, if the gap is under 60 mm | Excellent |
| Under the dishwasher plinth kick | No | No | Excellent |
| Inside the oven base cavity access | No | No | Excellent, when cool |
| Top of a wall cupboard | Yes for cats | No | Avoid in cat households |
| Open floor corner behind a bin | Yes | Yes | Avoid |
| Inside a closed pantry at floor level | Sometimes | Sometimes | Only with a latch fitted |
| Behind a fixed bath access panel | No | No | Excellent |
| Under a freestanding bookcase at floor level | Yes | Yes | Avoid |
For a typical two-bedroom home with a cat and a dog, ten to fourteen enclosed placements does the job: two to three in the under-sink cabinet, two behind and under the fridge, one to two at the dishwasher, one in the oven base cavity, two per bathroom vanity, two behind the washing machine, and one behind a bath panel if there is one. Every one of those is an enclosed cavity. Nothing sits in the open, and nothing sits above worktop height. If your home is larger, scale using the coverage arithmetic guide rather than spreading the same number more thinly.
Remove the remaining material, note roughly how much is missing, and call your vet or an animal poison line with the product label in front of you. Do not induce vomiting unless a professional instructs you to. Watch for drooling, vomiting, lethargy, unsteadiness or appetite loss and report anything you see. Then review why the position was reachable, because in almost every case the answer is a cabinet without a catch or a gap wider than it looked.
Young animals are more curious and less predictable, so restrict yourself to fully enclosed positions behind catches, and consider limiting treatment to rooms the animal cannot access unsupervised.
With enclosed sachet placements there is no treated open surface to walk on, which is the main reason this approach suits pet households better than sprays or open dusts. Our odourless control guide covers the alternatives.
If the visiting animal has access to the treated rooms and you cannot verify the catches hold, move the placements to inaccessible rooms for the visit and put them back afterwards.
Yes. Cockroaches forage into exactly those enclosed cavities, which is why enclosure protects pets without reducing effectiveness.
Walk the home at cat height and at dog height, use only enclosed cavities behind catches, keep bowls and beds a metre clear, write a placement card, check weekly, and store spares high. Ten to fourteen enclosed placements covers a typical pet household. One box provides that with plenty of spare sachets, and it is backed by a 30-day money-back guarantee.
Always use any bait product as directed on its label, and keep placements out of reach of children and pets. This is general guidance and not veterinary advice; if you think an animal has ingested any pest control product, contact your vet or an animal poison line immediately.
