High heat kills the bed bug instantly, heat especially above 49 degrees Celsius. Focus on mattresses, sofa seams, and crevices.
Always vacuum your mattress, carpets, and furniture thoroughly, and don’t forget the corners and cracks. Then, immediately, through the vacuum bag outside.
The Diatomaceous powder dehydrates the bed bugs, so sprinkle it under the beds, baseboards, and behind furniture as well.
You can use bed bug proof covers as they lock in already existing bugs and stop the new ones from entering in, so keep your mattress and box spring zipped up in these covers for at least a year.
Strip your bed and wash all linens, curtains, and clothes in hot water, as they hate heat, and then dry them in the high heat areas.
They love clutter, so always keep your space clean. Clear all the piles of clothes, papers and unused items as it can be their hiding place.
And still, if there are bed bugs and getting out, call a pest control expert as professional heat or chemical treatments are the safest bet many times.
