I am getting a lot of calls about cockroaches. That is because of very hot weather. Cockroaches and other insects are often attracted to homes because they are cooler. What should you do? First, never use pesticides. Spraying pesticides may kill a couple of roaches, but it will also kill a lot of beneficial insects. I had a person call me one time about how her exterminator sprayed around her home and killed a lot of praying mantids, but she never saw a dead roach. Generically spraying pesticides is totally unnecessary and certainly environmentally dangerous.
You can help prevent cockroaches from coming into your home by inspecting all incoming food products, all boxes, and any used furniture or appliances for the presence of cockroaches or their egg capsules. Do not store paper bags anywhere in the kitchen. Seal any holes or crevices around plumbing under sinks and behind toilets. Regularly vacuum and clean floors under the kitchen appliances. Keep all of your drains closed at night to prevent them from coming up from the sewer system.
There are a number of good baits available for controlling cockroaches. You can put equal amounts of baking soda and sugar out in flat containers and they will take it. There is a very good roach bait available commercially. It is Niban Bait and it is made from boric acid. It would probably be easier to get this product and use it if you are in an area where roaches are very common. You can’t buy Niban in stores, but it is available online. When using Niban, put it under and behind appliances, around hot water heaters, inside lower cabinets, in the garage and other places roaches will hide. Finally you can put pie pans full of beer outside around your home in various places and it will attract a lot of roaches. I have seen over 20 roaches in one pie pan full of beer and they don’t check IDs. They also like real beer, not lite beer. If you don’t want to kill the roaches, but put about a half inch of beer in a pie pan. They will go in the pan and stay. Just pick up the pan and dump the roaches into some kind of container so you can haul them off and relocate them. If you use beer, make sure you put it where pets can’t find it. Personally if I find roaches in my house, I pick them up and put them outside.
You don’t need an exterminator to spray toxic pesticides in your home.
