What are cockroaches and why act as soon as possible?
Cockroaches are the pest that generates the most callouts in Spain: cockroaches, bed bugs and rodents account for 70% of the 2025 pest-control enquiries, according to the sector's annual pest report, based on more than 23,700 real requests. At ERRADICAT we eliminate them in Barcelona and Girona with a proven method: insecticide gel applied at the detected entry points and adhesive monitoring traps, within a protocol of 3 visits in one month and a 1 year guarantee.
Beyond the reputational damage to a business, there is a real health risk: infested homes show significantly higher levels of the cockroach allergen Bla g 2 in household dust than pest-free homes. The earlier we intervene, the easier and faster the control. At the slightest suspicion, the best move is a professional inspection to establish the real extent of the problem, with a no-obligation quote.
Cockroaches or bed bugs?
They are not the same. Cockroaches come out at night in kitchens and bathrooms and leave droppings like ground coffee; bed bugs live in the bed and leave bites in a line and small blood spots on the sheets. The treatment is different in each case, and we identify it reliably at the inspection.
See the bed bug treatment →Prevention after the treatment
Once the pest is under control, keeping it away is simple: seal cracks and joints, remove food scraps and standing water, check inspection chambers and drains and ventilate damp areas well. Basic maintenance cuts off the sources and stops cockroaches from coming back in.
Cockroach species and evidence of their presence
Three species coexist in Barcelona and Girona. Identifying which one it is proves key, above all with the German cockroach, because the treatment strategy and the rotation of active substances against resistance depend on it.
German cockroach (Blattella germanica)
The most common indoors and the hardest to eliminate. Small and light brown, it breeds very fast and shows growing resistance to biocides. It is the main problem in kitchens and hospitality (HORECA); it demands identifying the species and rotating active substances to keep the treatment effective.
Oriental cockroach (Blatta orientalis)
Large and almost black. It prefers damp, cool areas: inspection chambers, drains, basements, downpipes and bin rooms. It usually climbs into homes from the sewer network and the communal areas of buildings.
American cockroach (Periplaneta americana)
The largest, reddish brown and able to fly short distances. It appears in drains, basements, garages and warm, damp premises, and is common in sewer networks.
How to know if you have cockroaches: warning signs
If you notice any of these signs, an inspection is worth arranging as soon as possible: seeing them in daylight usually means the infestation is already high. The earlier we intervene, the easier the control.
How we eliminate cockroaches
Our protocol combines a precise inspection with gel bait and monitoring traps, the reference method against cockroaches: the gel acts in a chain by transfer between individuals and reaches the hidden ones too, and in studies on infested homes gel bait treatment cut populations by more than 96% in three months.
Advice and inspection
We visit the home or premises to inspect and locate the sources: kitchens, bathrooms, inspection chambers, drains and behind appliances. We identify the species (German, oriental or American), because the strategy and the rotation of active substances depend on it.
Tailored solution
We apply insecticide gel bait at the strategic entry and activity points (hinges, skirting boards, joints and the backs of appliances) and place adhesive traps to measure the infestation and verify the treatment's effectiveness at each visit.
Follow-up and guarantee
At the following visits we check the traps, reinforce the gel where needed and confirm the trend, within a protocol of 3 visits in one month. The treatment includes a 1 year guarantee: if activity reappears, we intervene again.
Why choose ERRADICAT?
What sets us apart on every job
Gel at the entry points
We apply insecticide gel bait at the detected entrances and sources; it acts in a chain by transfer between individuals and reaches the hidden ones.
Adhesive monitoring traps
We place traps to measure the level of infestation and verify at each visit that the treatment is working.
3 visits in one month
A three-visit protocol over one month to check the traps, reinforce the gel where needed and confirm elimination.
1 year guarantee
The treatment includes a one year guarantee. If activity reappears during that period, we intervene again.
Treatment by species and against resistance
We identify whether it is the German, oriental or American cockroach and rotate active substances to beat biocide resistance.
Authorised biocides and licensed technicians
We use only products authorised by the Spanish Ministry of Health (Regulation EU 528/2012) applied by technicians holding the biocide applicator licence.
Local experts in cockroach control
We work across the provinces of Barcelona and Girona: homes and flats, restaurants and bars, homeowner communities and the food industry. In hospitality we apply gel and monitoring without closing the premises, and in communities we coordinate the treatment of communal areas, inspection chambers, bin rooms and downpipes to cut off the sources. Every intervention uses biocides authorised by the Spanish Ministry of Health, applied by technicians holding the biocide applicator licence, with documentation compatible with HACCP plans in food environments.
Frequently asked questions
The questions we hear most before a visual inspection
How much does it cost to eliminate cockroaches?
The cost is adjusted to each case, because it depends on the species, the surface area and the level of infestation. That is why we always make a prior inspection and give you a tailored, no-obligation quote. The treatment includes 3 visits in one month and a 1 year guarantee.
How do I know if I have cockroaches at home?
The clearest signs are seeing cockroaches at night when you switch on the light, droppings that look like ground coffee in drawers and corners, brown oothecae (egg cases) in cracks and joints, moulted nymph skins and a rancid, sweetish smell. Seeing them in daylight usually means the infestation is already high.
How long does the treatment take to work?
Our protocol is 3 visits spread over one month. The gel bait acts in a chain between individuals and reduces the population progressively; in studies on infested homes, gel bait treatment cut populations by more than 96% in three months. The adhesive traps let us verify the trend at each visit.
What precautions are needed during a cockroach treatment?
We use only biocides authorised by the Spanish Ministry of Health and entered in the Official Biocide Register (Regulation EU 528/2012), applied by technicians holding the applicator licence. The gel goes in very localised, inaccessible spots (joints, gaps and the backs of furniture), never on work surfaces or next to food, and the treatment does not require you to leave the home. We hand you the written usage instructions for every product applied.
Does the treatment carry a guarantee?
Yes, the cockroach treatment includes a 1 year guarantee within a protocol of 3 visits in one month. If new activity is detected during that period, we intervene again to reinforce the control.
Why are German cockroaches so hard to eliminate?
The German cockroach (Blattella germanica) breeds very fast (each ootheca holds 30 to 40 eggs and a female can produce several over her lifetime) and shows growing resistance to biocides, making it the main problem in hospitality. That is why we identify the species and rotate active substances to keep the treatment effective.
Suspect you have cockroaches?
Ask for a no-obligation visual inspection. We locate the sources, identify the species and tell you honestly the real extent of the problem and the best solution.
