De bor i hulrummet mellem formur og bagmur, og om aftenen og natten kan du h\u00f8re dem kradse og pibe. S\u00e5dan bek\u00e6mper du dem: Anmeld rotterne til kommunen, find indgangen, og fang rotterne uden gift, f\u00f8r du lukker hullet. S\u00e5 d\u00f8r ingen af dem inde i v\u00e6ggen.<\/strong><\/p>\n<p>Hulmuren er et godt skjul for en rotte. Der er lunt, m\u00f8rkt og uforstyrret, og hulrummet g\u00e5r ofte helt fra soklen op til tagfoden. Derfor g\u00e5r problemet sj\u00e6ldent v\u00e6k af sig selv. S\u00e5 l\u00e6nge indgangen er \u00e5ben, kan der komme nye rotter til.<\/p>\n<h2>Det vigtigste kort fortalt<\/h2>\n<ul>\n<li>If\u00f8lge Milj\u00f8styrelsen skyldes st\u00f8rstedelen af rotteforekomsterne i byer fejl i kloaksystemerne. Unders\u00f8g derfor kloakken f\u00f8rst.<\/li>\n<li>En rotte kan klemme sig gennem et hul med en diameter p\u00e5 kun 2 cm (Bolius, 2022). Selv sm\u00e5 revner i fuger og ved r\u00f8rgennemf\u00f8ringer kan v\u00e6re nok.<\/li>\n<li>Gift er s\u00e6rligt problematisk i en hulmur, fordi rotten ofte d\u00f8r i sit skjul. En d\u00f8d rotte inde i v\u00e6ggen er sv\u00e6r at komme til.<\/li>\n<li>Du har pligt til at anmelde rotter til kommunen. Det g\u00f8r du typisk via borger.dk eller kommunens selvbetjening.<\/li>\n<\/ul>\n<h2>Hvordan ved du, om der er rotter i hulmuren?<\/h2>\n<p>Det sikreste tegn er lyde inde fra v\u00e6ggen: kradsen, gnaven, piben og trippen. Lydene h\u00f8res oftest om aftenen og natten. I sin guide om rotter i boligen (2022) skriver Bolius, at gnavelyde, hvin og skrig fra v\u00e6gge og hulrum tyder p\u00e5 rotter frem for andre dyr.<\/p>\n<p>Disse tegn peger ogs\u00e5 p\u00e5 hulmuren:<\/p>\n<ul>\n<li>En skarp lugt af urin eller ammoniak, der er kraftigst ved bestemte stykker v\u00e6g<\/li>\n<li>Ekskrementer eller gnavespor ved soklen, i krybek\u00e6lderen eller ved ventilationsriste<\/li>\n<li>Smuldrede fuger eller sm\u00e5 huller t\u00e6t ved jorden eller omkring r\u00f8r og kabler<\/li>\n<li>Isoleringsrester, der ligger uden for et hul i murv\u00e6rket<\/li>\n<\/ul>\n<p>Er du i tvivl om, hvad du h\u00f8rer, kan du sammenligne med beskrivelsen af <a href=\"https:\/\/www.rattech.com\/hvordan-lyder-en-rotte\/\">hvordan en rotte lyder<\/a> og l\u00e6se om <a href=\"https:\/\/www.rattech.com\/hvornaar-er-rotter-mest-aktive\/\">hvorn\u00e5r p\u00e5 d\u00f8gnet rotter er mest aktive<\/a>. Det er v\u00e6rd at v\u00e6re grundig, for mange tager fejl. If\u00f8lge Bolius (opdateret maj 2025) fik kommunerne 217.021 rotteanmeldelser i 2024, og 56.991 af dem handlede om et andet dyr end en rotte. Omkring hver fjerde anmeldelse (ca. 26 procent) var alts\u00e5 ikke en rotte.<\/p>\n<h2>Hvordan kommer rotterne ind i hulmuren?<\/h2>\n<p>Rotter kommer typisk ind i hulmuren nedefra via kloakken. If\u00f8lge Milj\u00f8styrelsen skyldes st\u00f8rstedelen af rotteforekomsterne i byer og bym\u00e6ssig bebyggelse fejl i kloaksystemerne. En kn\u00e6kket eller ut\u00e6t kloakledning t\u00e6t p\u00e5 soklen kan f\u00f8re rotten direkte op i hulrummet. Derfra kan den bev\u00e6ge sig b\u00e5de vandret og lodret i muren.<\/p>\n<p>Det er de mest almindelige indgange til en hulmur:<\/p>\n<ul>\n<li><strong>Defekte kloakr\u00f8r under eller langs huset.<\/strong> Rotten graver sig fra bruddet op til fundamentet og ind i hulmuren.<\/li>\n<li><strong>D\u00f8de afl\u00f8bsr\u00f8r<\/strong> fra fjernede toiletter eller k\u00f8kkener.

Giften virker langsomt. N\u00e5r skjulet er en hulmur, ender kadaveret et sted, du kun kan n\u00e5 ved at fjerne mursten eller bore ind i v\u00e6ggen. Resultatet kan v\u00e6re stank og fluer i lang tid.<\/p>\n<p>Hvor l\u00e6nge lugten varer, afh\u00e6nger blandt andet af temperaturen og rottens st\u00f8rrelse. Det kan du l\u00e6se mere om i artiklen om <a href=\"https:\/\/www.rattech.com\/hvor-laenge-lugter-en-doed-rotte\/\">hvor l\u00e6nge en d\u00f8d rotte lugter<\/a>. Gift har ogs\u00e5 andre ulemper. Rovfugle, katte og hunde, der \u00e6der en forgiftet rotte, kan selv blive forgiftet (sekund\u00e6r forgiftning). Derudover er der resistens: Milj\u00f8styrelsens vejledning om bek\u00e6mpelse af rotter med kemiske midler (2020) beskriver en s\u00e6rlig resistensstrategi for antikoagulanter.<\/p>\n<p>Gift fjerner heller ikke \u00e5rsagen. Er kloakken stadig ut\u00e6t, kommer der nye rotter ind i hulmuren, n\u00e5r de f\u00f8rste er d\u00f8de.<\/p>\n<h2>Bek\u00e6mpelse af rotter i hulmur: s\u00e5dan g\u00f8r du<\/h2>\n<p>Du bek\u00e6mper rotter i en hulmur ved at fange rotterne og lukke den vej, de er kommet ind ad.
