Bed bugs are very resilient pests: they can survive for several months without feeding, hide in the smallest of spaces, and their eggs are protected by an extremely strong waxy coating. But the good news is that, like all insects, they also have their weaknesses. Temperatures, smells, substances, predators, etc. Here’s what you need to know to repel them.<\/p>\n\n\n\n\n\n

Key takeaways<\/h2>\n\n\n\n

\u27a1\ufe0f Heat above 56\u00b0C is their greatest weakness.
\u27a1\ufe0f Cold is only effective at -20\u00b0C for 72 hours.
\u27a1\ufe0f Certain smells bother them (essential oils, vinegar, aromatic plants) but are never enough to eradicate an infestation.
\u27a1\ufe0f They flee from light and dry, tidy environments.
\u27a1\ufe0f Diatomaceous earth is a very effective natural product.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Heat: their greatest weakness<\/h2>\n\n\n\n

If there is one thing bed bugs deeply dislike, it is high temperatures. Unlike cold, which slows down their activity but does not kill them completely, high temperatures cause rapid and irreversible death in both adult bed bugs and their eggs. In practice, their bodies become dehydrated.<\/p>\n\n\n\n

At what temperature do bed bugs die?<\/h3>\n\n\n\n

The recommended temperatures are based on mortality thresholds used in professional treatments (Certibiocide, INELP) and the work of entomologists such as JM B\u00e9renger (Marseille University Hospital).<\/p>\n\n\n\n

At temperatures above 56\u00b0C, adult bedbugs die within minutes<\/strong>; the very hot steam used in pest control instantly eliminates insects and their eggs when applied at a distance of 5-10 cm.<\/p>\n\n\n\n

Good to know: <\/strong>Bed bug eggs<\/strong><\/a> are covered with a highly resistant protective wax that makes them impervious to conventional insecticides. Heat therefore remains the most reliable method of eliminating them.<\/strong><\/strong><\/strong><\/strong><\/strong><\/strong><\/p>\n<\/div>\n<\/div>\n<\/div><\/div>\n\n\n\n

How can you use heat effectively at home?<\/h3>\n\n\n\n

Washing machine and tumble dryer<\/h4>\n\n\n\n

You can wash infested laundry at 60\u00b0C and then tumble dry it for 30 minutes at a high temperature to complete the treatment.<\/p>\n\n\n\n

Steam cleaning<\/h3>\n\n\n\n

You can hire a steam cleaner from specialist DIY stores. To be effective, the nozzle should be held 5-10 cm from the surface and moved slowly<\/strong> (\u2248 2 cm\/second). You can use your cleaner on your mattress, bed base, sofa, skirting boards, curtains, etc.<\/p>\n\n\n\n

In the event of an advanced infestation, do not hesitate to call in a certified professional<\/a>. This type of service provider uses tailor-made heat treatments. Some companies, such as Nocibilis, have developed heat chambers.<\/p>\n\n\n\n

In practical terms, this is a large 2.5 m x 3 m box called a Bugbuster, which is equipped with a heating and ventilation system. Contaminated items such as furniture, suitcases, mattresses, etc. can be placed inside, and a heat shock is then triggered to eradicate the bed bugs at all stages of their life cycle.<\/p>\n\n\n\n

2. Extreme cold<\/h2>\n\n\n\n

Bed bugs hate the cold… but only when it is really extreme<\/strong>. It must be applied for a long time and at a low enough temperature to be truly effective.<\/p>\n\n\n\n

In nature, these insects survive very well when temperatures drop slightly. This is why, in winter, in an unheated dwelling or in a bag left outside for a few hours, bedbugs do not die: they simply slow down their metabolism and can survive for several months without feeding.<\/p>\n\n\n\n
