What German Cockroaches Dislike
To keep these sneaky critters at bay, you gotta know what ticks them off. Let’s break down what makes German cockroaches cringe, focusing on their least favorite temperatures and living conditions.
Temperature Preferences
Now, German cockroaches are quite particular about their comfort zone. They enjoy chilling in places where the thermometer reads over 70 degrees Fahrenheit. According to those brainiacs at the University of Florida, if it gets too cold, like under 70, they’re outta there – it’s like cockroach kryptonite. They can’t handle icy spots, preferring warm and sticky locales to keep their creepy-crawly groove going. That’s why our homes and cities are like five-star resorts for them.
To find out just how chilly it has to be to send these guys packing, check out our take on what’s the coldest German cockroaches can survive.
| Temperature (°F) | Cockroach Party Level |
|---|---|
| < 70 | Snooze Fest |
| 70-90 | Party Zone |
| > 90 | Not Bad, Not Great |
Environmental Preferences
These pests have a knack for finding cozy, moist hangouts. Favoring steamy spots with some warmth and humidity, they dig into almost anything edible – starches, sweets, and greasy stuff are their jam, according to Penn State Extension. But get this, they don’t do well with places that are just drenched. Like, too much water is as off-putting as a desert.
They dodge ultra-dry or frosty settings, and they love hiding in shadows or among paper and cardboard, which help lock in their much-loved dampness (Pro Shield).
Peep our guide on German cockroach hidey-holes to unearth their favorite hangouts.
| Environmental Factor | Cockroach Liking Score |

|---|---|
| Cabinets Under Sinks | High |

A dry atmosphere and fewer cardboard heaps can make these spots less appealing to cockroaches. For solid tips on roach prevention, dive into how to get rid of german cockroaches.
