Stop Poison - Choose Exclusion

By the guy who’s been sealing rodents out since 2001 — and refuses to kill them for a living

Hi, I’m the owner of Seal Em Out LLC.
I’ve been doing rodent exclusion (a fancy way of saying “mouse-proofing houses so they can’t get in”) for more than two decades. I hold specialized rodent-proofing licenses in Connecticut and Florida — separate from regular pest-control licenses because most pest companies don’t actually do this work.

Here’s the uncomfortable truth nobody in a company truck will tell you:
1. Poison is the perfect business model — for the pest company
- It’s cheap
- It takes almost zero labor
- It pays the highest commissions
- Dead mice disappear in your walls
- More mice arrive as soon as the poisoned ones die
Chemical suppliers like Bell Labs train the industry to sell poison. Not a conspiracy. Just profit.

2. The Vacuum Effect is real
Kill 20 mice in your house with poison and 20 new ones rush in. Nature fills empty territory instantly.
The new rodents walk through blood, sebum oil, and decomposing bodies left by the last batch.
I can walk into a basement and instantly tell if poison was used. It looks — and smells — like a horror movie.
3. Poison fuels asthma, especially in low-income housing
Dying and decomposing rodents release massive allergens. Studies show rodent allergen levels are highest in low-income apartments — and so are childhood asthma rates.
Landlords hire the cheapest pest guy. He throws poison. Checks the legal box. Leaves.
Rodents still enter the apartment… they just die inside now.
4. Those black bait boxes? Wildlife killers
Technicians send me photos all the time: full-grown opossums dead inside “tamper-proof” bait stations.
Rain spreads the poison. Insects spread it. Owls eat dying rodents. The entire food chain suffers.
When customers switch pest companies, the old stations stay — and the new company adds more. Layers of plastic. Layers of poison.
5. The better way is not complicated
It’s called exclusion: sealing every gap a quarter-inch and larger with materials rodents can’t chew through.
I’ve seen whole neighborhoods drop to near-zero rodent activity once enough homes were properly sealed.
Add a non-toxic feeding station outside (like the new GoodBites contraceptive bait) and natural predators do the rest. Reproduction control is the icing. Exclusion is the cake.
6. I’m not fighting the industry anymore — I’m giving them an off-ramp
Most pest-control techs are good people stuck in a bad system. Poison is the path of least resistance because real exclusion used to be expensive and time-consuming.
So I built a per-foot pricing model that makes exclusion easier — and cheaper — for them to offer than another year of bait stations.
Jane Goodall said:
“Change happens by listening and starting a dialogue with the people doing something you don’t believe is right.”
I will never compromise on poison — but I will compromise on the path to a poison-free future.
The bottom line
Any building can be rodent-proof. Full stop.
Killing them is theater.
Sealing them out is the only permanent solution.
If you’re tired of the endless cycle of poison, traps, and dead-mouse smell, here’s the truth the industry hopes you never figure out:
Seal them out — for real.
Share this with anyone who’s ever found a black bait box in their yard, had a mouse in their pantry, or wondered why their kid’s asthma flares up out of nowhere.
Let’s make poison obsolete — one sealed house at a time.
