The most important part of pest management in your home is pest exclusion. The purpose of pest-proofing your home is to help keep cockroaches, ants, scorpions, centipedes, spiders, rodents and other pests out. It will also allow you to not have to hire a pest control company to spray pesticides all around your home or in it. Along with pest proofing your house, you need to remember to keep all of your sink, tub and floor drains closed at night. This will prevent cockroaches from coming up the drains from the sewer system or septic tank. If you don’t have a drain cover, you can fill a Ziploc bag with water and place it over the drain. That will keep the roaches out.
The first step is installing door sweeps on all outside doors that need them. If you can slide a piece of paper under a door, it needs a door sweep. Also add a door sweep to a door going into the garage.
Don’t leave any debris laying around the house. This is a good hiding place for cockroaches, scorpions and centipedes. If you have firewood, stack it away from the house as it will attract black widows and put some black plastic over it in the hot summer. That will discourage any pests from living in the firewood.
When you have branches touching the house or roof, it will allow acrobat ants and carpenter ants access. You should trim them back and keep them from touching the roof during the warm months. Also, you should sweep down any spider webs anywhere around the outside of the house. If you have drain pipes coming down from the roof, place a screen over the end on the ground. Mice can actually climb up the inside of a drain pipe, get on the roof and find a way into the house.
When you get to the garage, you will probably find that the door doesn’t close tightly and never will. There are almost always small areas at either side of the door when any insect or rodent can get in. As mentioned earlier, make sure there are door sweeps on the door entering the house. Put Niban Bait in any areas behind storage or shelves where roaches can hide. Niban will last three or four months, so you only need to apply it a couple of times a year. Niban is made from boric acid.
This procedure will keep most crawling insects and other arthropods out of your house. Keep anything that pests can hide in or under away from your house and don’t leave outside lights on any longer than necessary as they attract insects. Check your home every few months to make sure all of the work you did is still in place and effective.
