Prepare your Spanish home before cockroach season starts. Step-by-step checklist for April, May, and June – drain covers, gel bait, sealing, and more.

Cockroach season in southern Spain runs from May to October, with peak activity in June, July, and August. Preparing your home in late April or early May is the single most effective thing you can do.
Here’s your pre-summer preparation checklist.
Don't Wait Until June
By the time you see cockroaches in June, the breeding season is already underway. The best time to prepare is late April or early May – before cockroach populations peak.
Two Weeks Before Summer (Late April / Early May)
- Install or check drain covers on all bathroom and kitchen drains. Replace any damaged or ill-fitting covers. See our drain protection guide →
- Apply gel bait in key locations: behind the fridge, under the kitchen sink, around bathroom drain pipes, and inside any utility cupboards. Maxforce Gel is our top recommendation.
- Seal entry points – check around pipe entries, air conditioning units, and window frames for gaps. Use silicone sealant.
- Deep clean behind appliances – pull out the fridge, oven, and washing machine. Remove grease and food debris.
One Week Before Summer
- Place monitoring traps – sticky traps near drains and under the kitchen sink help you detect early activity.
- Check exterior perimeter – for villas, inspect around pool equipment, garden storage, and exterior walls for cracks.
- Stock up on products – order gel bait and spray from Amazon.es before summer demand drives up delivery times.
- Run all drains – ensure water traps are full, especially in guest bathrooms or rooms used less frequently.
During Summer (June–September)
- Weekly drain flush – run every tap for 30 seconds weekly. This keeps water traps full.
- Monthly bleach treatment – pour a capful of bleach down each drain in the evening.
- Reapply gel bait – check bait points monthly and reapply if dried out.
- Empty bins daily – food waste attracts cockroaches, especially in warm weather.
- Don’t leave pet food out overnight.
After Summer (October)
- Final gel bait application – catch any remaining cockroaches before they settle for winter.
- Deep clean again – behind appliances and under sinks.
- Assess and plan – note which areas had the most activity for targeted prevention next year.
Frequently Asked Questions
When should I start preparing for cockroach season in Spain?
Start in late April or early May — before cockroach populations peak. By the time you see cockroaches in June, the breeding season is already underway and infestations are harder to control. Early preparation means fewer cockroaches throughout summer.
What is the absolute minimum I should do before summer?
At minimum: install drain covers on all bathroom and kitchen drains, apply gel bait behind the fridge and under sinks, and run all taps weekly. These three steps address the primary entry point (drains), the primary treatment (gel bait), and the primary maintenance task (water traps).
How often should I reapply gel bait during summer?
Check bait points monthly and reapply if the gel has dried out. In very hot conditions (July–August in southern Spain), gel can dry faster. A full reapplication every 3 months is the standard recommendation. One syringe of Maxforce Gel is enough for multiple applications.
What products should I stock up on before summer?
Order before June to avoid summer delivery delays: Maxforce Gel bait (1–2 syringes per apartment), fine-mesh drain covers for every drain, silicone sealant for gap sealing, and sticky monitoring traps. All are available on Amazon.es.
Should I get professional pest control before or during summer?
Ideally, schedule a professional treatment in May (before peak season). If you need treatment during summer, most companies in Spain can visit within 48 hours. Twice-yearly professional treatment (May and September) is the gold standard for ongoing protection.
