Silverfish and Co.: No more creepy-crawlies in your home!

Ants, moths, cockroaches or bedbugs – anyone who has such animal roommates is often accused of poor hygiene. Insects and other crawling animals such as spiders usually come into the house to protect them from the cold. Or looking for food. They are magically attracted to a fruit bowl on the table or the bin with organic waste. If they find good conditions, they like to nest for a long time.

Many people feel uneasy when the little four-, six- or eight-legged friends are in the house. The urge to get rid of them very quickly is great and it is not uncommon for it to be quite violent. They are tackled with fly swatters, adhesive tape, insect spray, traps and baits. The result: Individual specimens are dead, but the next will surely come if they are not denied access.

“It can also happen that not only pests are caught, but also harmless specimens or even beneficial ones that are actually desired,” says Kerstin Effers from the consumer center in North Rhine-Westphalia. Like ladybugs, for example, which eat annoying aphids on plants.

In the following table we show you effective ways to get rid of annoying creepy crawlies:

Unwanted souvenir: bed bugs from the hotel

A big topic are bed bugs – blood-sucking insects that bite people. Markus Puschmann: “They are often dragged into apartments from outside or travel in from vacation as stowaways in their luggage.” Anyone who has a bed bug problem should not be afraid to quickly hire a professional pest controller. Successful control is difficult and requires good knowledge of the biology of the animals.

However, the search for a suitable pest controller harbors pitfalls. Kerstin Effers knows from experience in the day-to-day advice of the consumer advice center that there are many providers on the Internet who work unprofessionally and write overpriced invoices.

It is important that the commissioned company has the certificate of competence “Certified pest controller”. Kerstin Effers advises that customers should also insist that the pest professionals use the most harmless means possible: “For example, bait cans, gels and traps instead of sprays and nebulisers.

Beware: Many remedies also harm you

She advises first determining what type of crawling animal it is. A list from the Federal Environment Agency is helpful here, in which many typical pests, pests and beneficials that occur in our country are listed. It contains instructions on how to combat them if necessary.

The trade offers many means to combat pests in the house. The palette ranges from sprays, sprays, baits to electric vaporizers, strips, scattering agents and light traps.

“Caution is required when using them, because some of these agents pose significant health risks,” says Kerstin Effers. “Most bug sprays contain pyrethroids as active ingredients. These substances can lead to severe symptoms of poisoning in cats, including death. In humans, they can act as a neurotoxin.”

Instead of chemicals: sustainable pest control

But there are gentler methods than the chemical club to drive away the pests. “For example, pheromone traps are well suited as a supportive measure for containing pest infestation,” says Effers. Pheromones are synthetic attractants that attract males, who then stick to the trap. This interrupts the reproductive cycle and the pests can no longer multiply.

Ecology is also becoming more and more important to professional pest controllers. “Many environmentally friendly agents have been known for a long time and are now becoming more and more important to companies,” says Markus Puschmann from the Association for the Promotion of Ecological Pest Control in Essen: “Almost any pest infestation can be combated without a great deal of chemicals.”

For example silverfish. “They love the damp climate in the bathroom and kitchen,” says the expert. It is practically impossible to prevent them from coming into the apartment. Many people hardly notice them because they live very hidden and seek darkness. Or they don’t perceive them as pests at all because they are supposedly harmless. But they can cause considerable damage to books and wallpaper.

“In the event of a massive infestation, you should do something about it,” advises Puschmann. Instead of insect spray, which often contains toxic chemicals that can also harm people in the air, he recommends bait cans. “From these, the insects take in the deadly active ingredient with the food without it getting into the room.

“Spiders like to seek warmth in apartments during the cold season, much to the dismay of many people. Instead of killing them, it is better to catch them and transport them outside alive. Or you can get along with them. Because they are useful animals that insects like Eat flies and mosquitoes and even clean the house from vermin.

Locked out: This is how the creepy crawlies stay outside

It is often impossible to prevent insects and other crawling creatures from coming into the house. But you can make it difficult for them, for example with fly screens on doors and windows. Ants are blocked by closing their entrance and providing an alternative source of sugar.

“Food pests like moths are often brought along with purchases,” says Kerstin Effers. She advises checking newly purchased food for a possible infestation and then transferring flawless goods to sealable containers.

Sometimes pests come into the house in more unusual ways. “You have to be careful with used items. A flea market bargain or something found in bulky waste can definitely be infested with bed bugs and other insects,” says Markus Puschmann: “You should take a good look at what you’re bringing into your home.”
