Frequently Asked Questions

What are the most common pests in Spanish homes?
Cockroaches (both German and American species via drains), ants (particularly Argentine ants along the coast), and mosquitoes (including tiger mosquitoes) are the three most reported household pests. In rural and hillside properties, add scorpions, processionary caterpillars, and rodents.
Are pests in Spain dangerous?
Most household pests are nuisances rather than dangers. The exceptions are tiger mosquitoes (potential dengue vector), processionary caterpillars (toxic to dogs, cause dermatitis), and termites (can cause serious structural damage). Scorpion stings are painful but not life-threatening in Spain.
What is the best time of year to treat for pests in Spain?
Prevention is most effective in early spring (March–April) before populations explode. However, cockroaches require year-round management as they enter through drains regardless of season. Processionary caterpillar treatment should begin in autumn when nests first appear.
How much does pest control cost in Spain?
Professional treatment ranges from €80–450 depending on property size and pest type. A standard cockroach treatment for a 2-bedroom apartment costs €120–220. For detailed pricing, see our cockroach treatment cost guide.
Do I need professional pest control or can I handle it myself?
For mild infestations (seeing 1–3 pests per week), DIY methods like gel bait for cockroaches or Bti dunks for mosquitoes are effective. Professional treatment is recommended for severe infestations, termites, wasp nest removal, and any situation where DIY methods have failed after 4 weeks.
Are pest problems worse on the coast or inland in Spain?
Coastal areas face higher pressure from cockroaches (via sewer systems), mosquitoes (humidity), and ants. Inland and mountainous areas have more scorpion and rodent issues. Processionary caterpillars are worst in pine-forested hillside areas. Climate change is expanding pest ranges across all regions.
