put one can off in each room and leave for 2-3 hours. roaches tend to get in houses in paper bags, cardboard boxes, peoples suitcases. there are directions on the cans for you to follow.
Sprays do not kill spiders. They can tip toe right over sprays, but it can kill the bugs that they eat. Bugs, spiders and roaches can crawl from outside and the neighbors under the walls and up the pipes that enter the house.
Roach bait like Combat is good to put out for the roaches and the roaches will go into the bait stations and eat it and get it on them and go to were the roaches hang out in dark places and they will die to. This is a way to kill roaches that are inside the walls too. It comes in gel too.
Buy a box of plain corn meal (at the grocery) and put about a teaspoon of corn meal in each corner of every drawer and cabinet.
I killed a few spiders and a few roaches since February to now. It's kind of become a problem. I killed 2 roaches and a spder yesterday and 2 spders today. How can I get rid of the problem?
ps. I'm afraid of spders and we're moving next month, so I'm really worried we will find tons dead and alive. There has to be some kind of hole in our house but I don't know. I can't tell because I've seen them everywhere. In my room, living room, kitchen, dining room, bathroom, guest room....It's literally just become a problem. Any advice?
