Question

Will laundry detergent kill roaches?

I have some roaches in my bathroom and have been trying to get rid of them. They keep coming back after I spray them with roach killer?

Will putting laundry detergent on the roaches kill the roaches?

Answer 1

Laundry detergent will kill roaches and here's how you make some roach bait with laundry detergent.

Combine one part laundry detergent with one part sugar in a bait station or lid.

Add a pinch of borax if desired to make the bait even more effective; borax is commonly used to control roach infestations. The sugar is used to attract the roaches to the bait.

Answer 2

Yes laundry detergent does kill roaches.

I've had great success using laundry detergent for killing roaches.

I also recommend using some roach fogger to fog the home to get rid of roaches even faster or even hire an exterminator if you can afford to do so.

Another option is to spray some RAID roach spray which is very effective at killing roaches.

Set out some roach motels and sticky glue traps as well to trap roaches as they crawl across them.

Add a bit of breadcrumbs to the glue traps to attract the roaches.
