Some pet owners may worry that a pet who has contact with cockroaches may become unwell. Other pet owners may never have thought of this possibility. Yet other have been known to think that cats can keep cockroach at bay. Are pets and cockroaches a perilous combo? And if so, can cockroaches endanger them?
Pets can get ill from eating cockroaches or coming into contact with contaminated surfaces. While the occasional cockroach may not cause immediate harm, several risks are involved:
Cockroaches often carry bacteria like Salmonella, E. coli and Listeria. These bacteria can live on the cockroach’s body or in its faeces. If an animal eats an infected cockroach or licks a contaminated surface, it could develop an upset stomach or a more serious gastrointestinal infection.

Cockroaches can act as intermediate hosts for parasites such as worms. If a domestic cat eats an infected cockroach, it may end up with parasites like tapeworms, which can affect weight, appetite and overall health.
If a cockroach has come into contact with pesticide or bait, it may carry trace amounts of poison. A pet that eats the cockroach could ingest these toxins. This may lead to symptoms like drooling, vomiting, tremors or worse. For example, some over-the-counter cockroach baits contain substances that are harmful to pets. If they touch or ingest bait or poisoned insects, they may become ill. We always recommend using professional pest control to ensure safety for both pets and people.

Cockroach shells contain chitin, which is hard to digest. Sharp shell fragments can irritate the stomach or throat. In smaller cats or kittens, there’s also a minor risk of choking. Cats and dogs may chase insects out of curiosity. Occasionally, they catch one. Bear in mind that cockroaches breed quickly and hide well. They can thrive behind walls, under floors and in kitchen cupboards. Cockroach populations can grow unnoticed. In fact, many insect species are nocturnal and avoid light and noise.
Pets with sensitive immune systems may have allergic reactions after contact with cockroach body parts or faeces. This might show up as sneezing, skin irritation or respiratory symptoms. While one cockroach probably won’t harm a healthy animal, regular exposure or ingestion increases health risks. If you suspect your pet is ill after eating or touching a cockroach, it’s best to contact a vet promptly.
We also recommend professional intervention to remove cockroaches safely and completely. It also keeps your cats safe. Pets deserve a clean, healthy environment too.
