1. Seal any sources of food.
It is good for your health and hygienic, for any food you have, make sure you store the food appropriately in airtight containers so that the mice and roaches are out of reach. When they find no food in your home, they will see your home as the less attractive place, which is a good thing, since they are not your guests.
The same goes to the pet food. Make sure you also discard as well as keeping the pet food properly.
2. Food Crumbs
Food Crumbs are the next thing the mice and roaches will look for in your home after you seal all the food safely. To minimize food crumbs in your home, eat in a polite manner. Ideally, you should also clean the kitchen and dining room every day.
3. When you have done the two things mentioned above and those roaches and mice are still coming back(very unlikely) then you might want to use some poison baits on them. A roach or mice eats the poison bait and brings back to the main nests, after that the poison spreads and kills every single one of them. Fast and effective. Well, if that still could not finish the job, then you might need to call in the exterminator. Since the chemicals they use to kill roaches are as harmful to us humans as to roaches and mice, ask the exterminator to focus on the infested areas. Those chemicals are very significant irritants. After the job is done, ventilate your home by opening up windows and doors and let the wind carry the chemicals and odors away.
Other tips for the kitchen:
- Stop using any cleansing fluids/detergents if they cause any irritation to you or your family
- Ventilate your home properly
- Cleanliness is key. Make sure the kitchen, tools, food ware, utensils, everything is clean.
