We have that prob with ants. Get bug sprays and go through all the cracks in the wall and the windows
I dont think the vinegar lasts very long make sure ur house is sealed up well around doors n windows n if u dont wanna try chemicals right away peppermint oil or anything with citrus is supposed to repel them as well as keep clutter to an absolute minimum. Ive been on a rampage since we bought our house last summer n theyre bad coming in from a field behind our house. Just be sure if u use any kind of oils u check to make sure theyre safe I dont think peppermint oil is good for cats but ok around dogs n kids
Look up home remedies I have heard mixing vinegar and water into a spray will get rid of them.
They I will just spray all over. Doorways. Windows. Outside of the door and windows . Corners on the ground. The whole ground lining. But have someone else do it don't inhale those chemicals. And if u have carpet vacuum everyday. And look around and see if there are any holes then patch them . I use to have a Roach problem. when I moved in I didn't know but they were coming from all over once I got settled in. So I even put mouse traps the glue kind on the floor behind the stove, refrigerator etc. anywhere u usually won't clean daily. and it worked.
This is so crazy I just saw a spider on my baby organizer ! I'm so mad.
The only problem is i have no clue where they are coming from.. i live on the ground level of a 4 plex and ive found them in both our bedroom and the bathroom.
If its bad i know they have a spray that u put around the perimiter of your house or where ever they are comming from. They sell them at a menards or home depot. Idk if u have one around you. But i heard it works pretty good.
