Moreover, it might become challenging for them to find sources of water outside (yet another reason for them to move inside an inhabited building).


How to Get a Cockroach to Come Out of Hiding?

There are a few simple ways that can help you get a cockroach to come out of its hiding place.


Cockroach Baits

Cockroach baits are something that attracts cockroaches, but you would have to wait a bit for it to happen. Take some sticky paper, a bowl, and leftover food. Place the paper and leftovers inside the bowl. The smell will attract the roaches, they will get inside the bowl, but the sticky trap won’t let them get out.

You can also mix borax with sugar and spread the mixture around the hiding places. The cockroaches will be attracted to the sugar and the borax is the poison that will kill them. Of course, you can always use special cockroach baits as well.

Lamp/Light

If you know exactly where the cockroach is, get a lamp and shine it into the hole where the creature is hiding. Cockroaches hate bright light, so the chances are high that it will run towards a shadow. You can switch off the lights in the room and leave only the lamp on for a more powerful effect.


Repel Them Out of Hiding

Last but not least, you can create a homemade mixture that will scare/repel these insects away instead of attracting them. For example, a finely chopped onion mixed with boric dust spread next to the hiding places will make the creatures leave their shelters in a few hours.


What Causes Cockroaches to Come Inside?


Why Do Cockroaches Come in the House?

Why Do Cockroaches Come in the House

There are three main things that can make roaches come into your house and those are food, water, and shelter. The insects are always in search of the first two. When it comes to shelter, some species that live outdoors tend to move indoors when it gets too cold or too hot.


Why Do Cockroaches Come Out During the Day?

Food is the main thing that motivates cockroaches. If they feel hungry, they might come out of their shelter even during the day. Seeing cockroaches running around in the middle of the day is not a good sign.

Probably, the infestation is so severe that these insects have to come out of their hiding places in order to get to the food sources faster than their other “colleagues”. They might also come out during the day if you have scared them.


Why Do Cockroaches Come Out Only at Night?

The fact that cockroaches come out when it’s dark protects them from being seen and eaten by other creatures (or killed by people). Basically, these insects have evolved into nocturnal species.


Why Do Cockroaches Come Out in the Summer?

Roaches love warm and humid weather. It is easier to find food and water sources during summer. For that same reason, cockroaches reproduce much quicker during summer. However, if it gets too hot outside, these insects will start looking for shelter.


Why Do Cockroaches Come Out in the Heat?

The truth is that cockroaches don’t like when it gets too hot outside. But moderate heat is a different story. When temperatures rise, cockroaches are encouraged to forage for food and reproduce faster. That might be because during the hotter months it is usually easier to find food sources.

Moreover, we should not forget that cockroaches are nocturnal creatures. So, the chances are high that they will be hiding during the extreme heat in a colder shelter.
