How to Keep Cockroaches Out of Your Home

There are usually only two types of cockroaches we see in the West Palm Beach area.

American cockroaches, often called Palmetto Bugs, are the big scary ones. When you run from the room to get away from a roach, it’s usually one of these. They are about two inches long, reddish-brown in color and have wings.

American cockroaches come from outside of your home through cracks and crevices or by occasionally slipping inside an open garage door or other entry point. If you are seeing them frequently, more than a few each week, they are most likely coming from the sewer system. This is usually the case if you see nymph/smaller American cockroaches.

Sometimes an entry point from the plumbing opens up which allows American roaches to enter from the sewer system. This could be a cast iron pipe under your home, a broken wax seal at the base of one of your toilets, a kitchen remodel that leaves a pipe uncapped, etc.

The other type of roach we see is the German cockroach. While these are smaller than American cockroaches, they reproduce much more quickly. We’ve been in homes with so many German cockroaches they when a picture is lifted off the wall, at least ten live roaches that were eating the glue behind the frame fall to the ground.

If untreated, German roaches can multiply into the thousands fairly quickly if they have access to enough food and water. German cockroaches do not live on the outside of homes, so they must be physically brought in. They can travel in clothing, furniture, food packages, etc.

Do NOT Use Contact Kill Products

Yes, there are sprays for cockroaches that are sold in lots of local stores. And they are great at killing cockroaches on contact. If you see a big American Cockroach, this can be the best temporary solution.

Keep in mind it is only temporary though – as in it will kill the roach you spray and that’s it. These types of cockroach sprays do nothing to stop them from getting into your home.

These roach sprays are a really bad idea if you use them on German cockroaches. Yes, it will also kill them on contact. But it will also cause the many others that are behind your appliances and in cracks and crevices to retreat further into these hiding places.

This makes long term control more difficult since there is no way this spray will be able to kill the ones in the walls and behind appliances. It will make any cockroach bait and non-repellent sprays ineffective as long as it is being used.

Whenever we treat a home professionally for roaches, we rely on a combination of products to achieve long-term cockroach control. We will use gel baits, granular baits, insect monitors, and non-repellent sprays applied to cracks and crevices. We also will focus on reducing the exterior population of roaches around the home to minimize the likelihood of entry.

Seal Exterior Cracks and Holes

Pest Entry Points

While physically blocking cockroaches from gaining entry to your home seems like the most common sense answer, it is the least often method used by homeowners. We prefer to use silicone caulk that dries clear to seal small cracks and holes that appear in all homes over time. By reducing the access points roaches have, less will physically be able to get inside.

We also recommend sealing any potential interior plumbing entry points that are accessible. Make sure the base of all of your toilets are properly caulked to prevent roaches from entering from the sewer system.
