Spiders at Home and in the Garden in Warsaw — Are They Dangerous and How to Get Rid of Them
A house spider in the bathtub or a garden cross spider on the terrace can be frightening, but Poland has no species dangerous to people — we look at when it's worth reducing their numbers and what that treatment looks like in Warsaw.
Are spiders at home dangerous?
Spiders trigger strong fear, but in Poland's climate none of the species found here threaten an adult's health.
Not venomous to people
Their venom is used to subdue insects, not to defend against humans.
Rarely bite
They only bite in self-defence, when they feel directly threatened.
Help control other insects
They feed on flies, mosquitoes and moths, naturally reducing their numbers.
Enter homes by accident
They look for warmth, moisture and hiding spots, especially in autumn.
How to recognise an increased spider presence
Watch out for the following signs:
- Numerous cobwebs in room corners, the basement or the garage
- Large circular webs on the terrace, in the garden or between plants
- Fast-moving spiders visible in the evening on walls and in the bathtub
- Increased activity in autumn, when males search for mates
- Presence of other insects (flies, mosquitoes) attracting spiders as a food source
How do we reduce the number of spiders? Methods that work
We match the method to the location and scale of the problem:
Barrier sprays
Limit spiders entering the building from outside.
Web removal
Physically removing existing webs from the facade and interior.
Sealing entry points
We block cracks in windows, doors and foundations.
Reducing the food source
Eliminating other insects makes a spot less attractive to spiders.

Did you know...?
When are spiders most visible?
September–October
is the peak of the season, when adult male house spiders wander in search of females and more often end up indoors.
How to prepare the house and garden before the treatment?
For the treatment to be fully effective, follow these tips:
Remove visible webs
Makes it easier for the product to reach the spiders' hiding spots.
Check windows and doors are sealed
Makes it easier to install protection against them entering.
Reduce moisture sources
Dry out the basement and utility rooms.
Reduce outdoor lighting
Fewer insects attracted by light means fewer spiders hunting near the house.
