What Temperature Kills Roach Eggs?

Cockroaches and their eggs are pretty resilient creatures.

To effectively eliminate cockroach eggs, you’d need to expose them to temperatures above 66℃ or below 18℃.

But here’s the catch: these temperatures need to be sustained for a good amount of time to ensure they’re gone for good.

Considering that these sneaky pests tend to lay their eggs in protected spots like inside walls or tucked away in crawlspaces, using temperature as your sole weapon might not always be practical.

How to Use Temperature to Kill A Cockroach?

When we think about pest control, we often imagine chemical solutions.

However, temperatures can be an effective ally against these resilient pests, without the harmful side effects!

Why Use Heat or Cold to Kill Cockroaches?

Many traditional methods to eradicate cockroaches can be pricey and may leave toxic traces. Popular chemical solutions are increasingly proving ineffective.

Studies show that some roaches are becoming resistant to pesticides, and in some scenarios, their numbers even increase post-exposure! Therefore, using extreme temperatures can be a more effective and safer strategy to eliminate these pests.

How to Use Heat to Kill Cockroaches?

So, how hot does it need to be to send these pests packing?

A temperature of 120°F (49°C) and above will exterminate cockroaches within a few hours. Notably, the German Cockroach, known for its impressive survival tactics, can endure up to four days in these sweltering conditions.

However, given a week or two, they will meet their end. A hotter environment will expedite this process.

Though roaches thrive in warm conditions—after all, they are tropical by nature—they do have their limits. Even at a balmy 110°F (43°C), these pests prosper, thanks to their protective exoskeleton.

This exterior not only shields them from temperature changes but also plays a vital role in their breathing process, absorbing moisture from the air.

Yet, when faced with temperatures surpassing 120°F (49°C), their protective mechanisms break down, leading to dehydration and, ultimately, demise.

How to Use Cold to Kills Roaches?

Can cockroach eggs survive cold? Not at all! Cockroaches will succumb when the thermometer reads 15°F (-9°C) or colder.

You might think the onset of winter spells doom for these creatures, but that’s not always the case.

When temperatures descend below 40°F (4°C), roaches slow down their activities, including breeding.

They either adjust to the cooler temperatures or scout for warmer refuges.

Homes become their winter havens, with nooks, crannies, boxes, kitchen storage, basements, and plumbing systems offering both warmth and food.

This means that, come spring, you might discover an unexpected roach boom in your home.

Prolonged exposure to temperatures ranging between 0°F and 15°F can be deadly for roaches.

In these icy conditions, they’re unable to maintain essential body temperatures, causing their respiratory systems to freeze and halt, leading to their demise.

What Is The Ideal Temperature For Cockroach Development?

Cockroaches, despite being universally disliked, are intriguing creatures with preferences tailored to their species.

Different species favor distinct temperature bands where they flourish the most.

Here’s a quick glance at four common household cockroach species and the temperatures they love:

  • German Cockroach: Between 59 and 95 °F
  • American Cockroach: A cozy 68 to 84 °F
  • Oriental Cockroach: Prefers 68 to 86 °F
  • Brown-banded Cockroach: Likes it between 77 and 91 °F

Although these little invaders can adapt to temperatures outside their favored ranges, there are definite limits to their resilience.

Extremely chilly or scorching conditions can challenge their survival instincts.

It’s noteworthy that when roaches are within their ideal temperature range, they tend to reproduce and grow at a much faster rate.

This explains why many households often witness a roach population boom during the warmer spring and summer months.

Speaking of roaches, did you know you don’t always have to resort to temperature changes to deter them?

Essential oils, particularly peppermint oil, have been found to be effective roach repellents.

And just a fun tidbit before we wrap up: not every critter that looks like a cockroach is actually one!

There are several bugs out there that might just fool you with their roach-like appearances. Keep an eye out!

Does Temperature Affect Cockroach Behavior?

As the mercury drops, cockroaches instinctively switch to energy-saving mode.

When the chill sets in, particularly under 7°C, these critters essentially put their reproductive and growth processes on hold.

Instead of being active, their main priority becomes seeking warmth to outlast the cold season.

Their hideouts of choice?

Typically dark and toasty nooks and crannies, such as beneath pipes, within wood stacks, or in the cozy corners of a basement.

This reduction in activity also means they’re less likely to venture out, which is why during the winter months, you might notice a decrease in your cockroach sightings.

Quite the strategy for such small creatures, wouldn’t you say?


Understanding “What temperature kills cockroach eggs” is vital in our battle against these persistent pests.

As we’ve explored in this blog, specific temperature ranges can be an effective deterrent in eliminating the next generation of cockroaches.
