Getting rid of unwanted roommates
My spouse and I just moved into an apartment a few days ago and we have somewhat of a roach problem. I think they're German roaches but I'm not entirely sure. The largest ones I've seen are only as long as a dime. We see about 5-10 crawling across the floor/walls a day and I would really like to get a handle on it.
The last tenant in this apartment was somewhat of a disaster, from what we've gathered. He made a badly done DIY fire pit in the small yard and cooked food out there which caused an ant infestation that I'm also trying to take care of- any tips are welcome. I used a pet safe ant killer this morning and am waiting to see what it does for the problem- He got evicted about a month ago and was here for quite a while before that. Based on all the little problems we've found (leaky faucets, bugs, dented walls/doors, loose hinges) it's pretty clear that he didn't take super great care of the place. It seems like he was a bit of a mess and we're trying to straighten everything out as we move in. Twice monthly pest control is included in our rent already and they bug bombed the place the day before we moved in.
I put sticky traps all over the house. We have two dogs so we don't want to do anything with poison in case one of them eats a roach that has eaten poison and gets sick. We have diatomaceous earth on the way and when I finally get all these boxes unpacked, I'm going to mop the place with peppermint oil and sprinkle cinnamon along the baseboards and corners. We're fairly clean and don't keep any open food out. We have a trashcan with a lid and I put all the dog food in air tight containers so the roaches don't get into it.
I know it's only been a few days and the problem will likely get better as we clean and truly move in, but I want to get a head start on it as I HATE bugs.
