I have a roach infestation in my apartment I believe they come crawling somewhere down near the garbage 3 levels down, they pretty much come through my main door and stay in the kitchen.
Recently I purchased some Mortein roach bait to kill these tiny critters, they're small not the large ones. The product doesn't seem to have any effect? Do they really work? I have checked out some reviews and most say they aren't reliable.
We have used the small plastic square ones with holes in the side… and they did have an effect.
The pest self treatment spray at Bunnings… about $15 for 3 litres with a sprayer… work well if you spray around where they are getting in. Lasts about a month or two but you will get plenty of sprays from the sprayer.
Make sure any food source outside is removed, especially pets food dishes. Also remove any debris or junk laying around and keep the lawns mowed.
