Bed bugs are difficult to get rid of! With infestations on the rise, insecticide treatments are now the norm, with varying degrees of success. However, does this pest have any natural predators? Are there other insects that feed on bed bugs? Find out in this article.<\/p>\n\n\n\n\n\n

In brief<\/h2>\n\n\n\n
\n
\n

\u27a1\ufe0f Natural predators such as the fast-moving centipede exist, but they are not enough to eliminate an infestation of bed bugs.<\/p>\n\n\n\n

\u27a1\ufe0f Introducing these predators into your home is not recommended.<\/p>\n\n\n\n

\u27a1\ufe0f Heat and chemical treatments remain the only truly effective methods, as they destroy both adults and eggs.<\/p>\n\n\n\n

\u27a1\ufe0f Prevention is essential.<\/p>\n<\/div>\n<\/div>\n\n\n\n

1) Spiders<\/h2>\n\n\n\n

Spiders are formidable natural predators. These hunters wait patiently in their webs or move silently at night to capture various insects. Are bed bugs among their prey? Yes, for some species large enough to eat them. <\/strong>This is the case, for example, with the Thanatus flavidus<\/a> found in Eastern Europe.<\/p>\n\n\n\n

However, it would take many individuals to overcome an infestation of bedbugs<\/strong>, not to mention the fact that you would have to live with them in your home…<\/p>\n\n\n\n

A spider cannot eliminate a swarm of bedbugs hidden in bedding or under a bed base. <\/strong>Furthermore, they cannot reach the eggs, which are stuck and well protected in corners.<\/p>\n<\/div><\/div>\n\n\n\n

\n

2) The rapid scutiger<\/h2>\n\n\n\n

The rapid scutiger<\/a> (Scutigera coleoptrata<\/em>) is a thin, fast centipede, recognisable by its long legs and lightning speed. A predator par excellence<\/strong>, it feeds on a multitude of insects, including pests such as cockroaches, flies… and sometimes bed bugs.<\/p>\n\n\n\n

\n
\n

Thanks to its mobility and long antennae, it can squeeze under skirting boards, behind furniture or into cracks, which are popular hiding places for bed bugs.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Its bite injects a mild venom that is harmless to humans but sufficient to immobilise an adult bed bug.<\/p>\n\n\n\n

However, as with spiders, its action is very limited. Its presence in a house or flat is not enough to eliminate all parasites. It should be noted that an infestation of bed bugs can spread very quickly, with each adult female laying 5 to 10 eggs per day.<\/p>\n<\/div>

3) Cockroaches<\/h2>\n\n\n\n

Cockroaches, particularly German cockroaches (Blattella germanica<\/em>) and Oriental cockroaches (Blatta orientalis<\/em>), are opportunistic omnivores<\/strong>. They feed on anything they can find: food scraps, organic waste, dead insects… and sometimes live or dead bed bugs.<\/p>\n\n\n\n

In an infested environment, a cockroach may nibble on weakened adult bedbugs or newly hatched<\/strong> ones. However, in practice, no one wants cockroaches in their home.<\/p>\n<\/div><\/div>\n\n\n\n

\n

4) Lizards<\/h2>\n\n\n\n

In some hot regions, lizards, such as geckos, are opportunistic hunters that feed on many insects, including flies, mosquitoes and cockroaches. Their keen eyesight and rapid movements enable them to spot and catch moving prey.<\/p>\n\n\n\n

In theory, a lizard could therefore attack a bed bug that moves out of its hiding place, for example on a wall or a sheet<\/strong>.<\/p>\n\n\n\n

\n
\n

However, lizards are outdoor animals and, unlike bed bugs, are not active at night.<\/p>\n<\/div>\n<\/div>\n<\/div>

5) The masked assassin bug<\/h2>\n\n\n\n

The masked assassin bug (Reduvius personatus<\/em>) is a predatory insect belonging to the heteroptera family. It is sometimes nicknamed the \u201cmasked bug\u201d because it can hide by covering itself in dust using sticky hairs.<\/p>\n\n\n\n

This small insect feeds on many biting and sucking insects such as fleas, termites and bed bugs! With its powerful rostrum, it pierces the cuticle of its prey and sucks out its contents.<\/p>\n\n\n\n

\n
\n

Unlike other predators, the masked reduviid can hunt in more confined areas, including near mattresses or in gaps in furniture.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Unfortunately, its bite, although rare, can cause a painful <\/strong>reaction in humans similar to a wasp sting.<\/p>\n<\/div><\/div>\n\n\n\n

\n

Bonus: mushrooms?<\/h2>\n\n\n\n

Mushrooms still have many secrets to reveal to us! Some specimens could help fight bed bugs. This is the case with Beauveria Bassiana<\/a>, a pathogenic fungus that penetrates the bed bug’s body and feeds on its host until it dies<\/strong>.<\/p>\n\n\n\n

It is also used in agriculture to control certain harmful insects.<\/p>\n\n\n\n

Are natural predators sufficient to get rid of bed bugs?<\/h2>\n\n\n\n
\n
\n

The answer is clear: no<\/strong>. Their presence in a home infested with bed bugs is far from sufficient to eradicate the problem.<\/p>\n<\/div>\n<\/div>\n\n\n\n
